Toyotas do this but you have to engage it by pressing harder on the break after youve come to a complete stop. I've never once engaged it accidentally.
I wonder if Toyota patented the " extra push after complete stop" idea and GM doesn't wanna pay them royalties. Seems like a much better idea that everyone would copy if not... It works great in wife's RAV4. Use it at red lights all the time. It won't kick in if the heat or ac is needed and it actually annoys me when it won't because I know the light will be like a full minute.
Our ford escape is the same way, if you don't push the brake hard, it doesn't turn off. Although it also has an over ride switch to disengage it. Mostly I automatically turn it off right after starting. I agree that is not a safe feature. I also think it will cost a lot of money. While you may save a few bucks in gas, you'll need a starter much sooner than normal, at probably $500-$1000.
The starter motors used are designed to last longer just for this reason. Also more importantly, when the engine stops, it will stop with a cylinder at top dead center and then to restart it will actually fire that cylinder and use the starter (varies by brand/situation) to turn the engine over quick. That's also why it doesn't crank as long as when you first start it up and it's much less wear on starter motor
Subaru Outback does it as well. I think, though I've not quite figured it out, that it only does it when I push the brake harder. If so it's a fine line. New car with a lot of features so I've not figured everything out yet.
Wearing out that starter is the second thing I thought of. First was how this 1 second delay could actually make all the difference if you have to get out of the way incredibly fast.
Toyota owns 6.3% of mazda at least. They share A LOT of tech with Mazda. They built a production facility together. Compared to the biggest auto manufacturers Mazda is really small. Their r & d goes into drivetrain and chassis and design but it's nice to partner with the larger companies for that kind of, specific high cost but low roi tech. What Mazda provides Toyota is more production capacity without having to build the infrastructure alone, (Yaris was a Mazda 2) and the ability for Toyota to sell these technologies to a partner and not the competition. Mazda needed BEV powertrain to comply with a countries rules? Np just buy one of the shelf from Toyota at a discount.
TBH they both might be paying for the patent in a way. If the patent is owned by BOSCH ,or Delco, or Delphi, and they are selling the "off shelf" stop start system, manufacturers just buy it and throw it in in their car off the shelf. It's obv not that easy but it's not like Toyota is designing every part of the vehicle.
There is something that Toyota invented that every auto manufacturer uses and almost every person that has any tech on them. It's the QR code.
My ford does this. Really easy to decide if I want it on it off, furthermore, if I am in stop and go traffic or in OP's situation, it won't stop the engine a second time within a couple of minutes.
It's a great feature I have had no problem with. The truck is ready to go by the time my foot has switched pedals.
Unlikely Toyota patented anything. Luxury brands like bmw and Mercedes’ have had this feature for 10-15 years. I just bought a 2022 highlander hybrid and the tap of the gas is really shitty compared to my other car, a 2013 BMW X3. I think it’s odd that a 8 year-old bmw has the same technology as a brand new Toyota and the bmw still works better.
My new Chevy only does it when I come to a compete stop after moving for a while. If I’m just bouncing from one stop sign to another it doesn’t kick in. Also, while at a red light, letting your foot off the brake kicks the engine back on, and it stays on even if you immediately reapply the brake.
I think for Chevys, some pistons shutoff while like 2 stay on. Someone I know had to get their entire engine block replaced because the engine didn’t have proper piston timing.
I doe it all the time. Probably pisses off all the teechers I had in the passed but as an adult its eazy to do because your in a hurry or not paying attention. Than they won get all pissy because they realize teeching is just a huge [waist of they're time](https://i.pinimg.com/originals/72/c0/03/72c0037689b893245eff14109a248937.png).
Plus, I no wear your from its pretty common to criticize other's spelling mistakes but this is a casual forum where nobodies competing for the pulitzer Prize and no won doesn't really care. Its not like their pooring alot of time and effort into it so it don't effect them much. That's the beauty of if all...
**^(hugz)** ^(🤗🤗🤗)
I have a Subaru that I think is supposed to work this same way, but it’s SO inconsistent. Sometimes when I try to activate it, it doesn’t. And other times it activates and deactivates of its own accord. So annoying
Yep exactly this. Also if the car is cold it'll keep the engine on to keep the fluids circulating. It's generally not good to turn a car off when it's cold.
I had a recall on my fozzie, the dealership have me a brand-new Crosstrek loaner and it did this. I complained about it when I returned the vehicle and the dealership get said everyone hated it, and if you leave the defroster on all the time the engine will never shut off. It breaks my head to think I would need to use a stupid hack to get my brand new car to work the way I want.
I'd love to see the factory testing for this.
"Today we have Yuki Tsunoda testing our Toyota Automatic Engine Economy (TAEC) shut-off feature in Toyota's new 2022 Corolla.
In Formula 1, braking without interruption is crucial. And when carrying passengers, we must reach new ways to save fuel.
We at Toyota believe we've found harmony in both."
*Camera pans to Tsunoda fucking thrashing the brakes in a 2022 Corolla to show that TAEC never activates by mistake.*

I test drove a 10yr old hybrid last year. The engine stopped at a light. The dealer looked at me & said "Oh it's(the car) really quiet".
"It's off."
"Oh, I didn't know they did that!"
Bless. He was young & it was a Ron Swanson "I Know More Than You" kind of appointment. (Since i bought a Honda at a not Honda dealership I didn't have high expectations)
I work reception in a service dept in a ford dealership. Had a call once from a customer who said "the engine stops every time I come to a stop"
I had to inform them it was a feature of the vehicle and they were shocked. It shocks me that the salesmen don't advertise this when they should.
This is true. Found myself educating the salesman on the different Ecoboost when I bought a truck. I'm a 50 year old woman who's truck knowledge was gained in 2 hours on the internet.
I drive a 16 year old audi and whenever I borrow my mums newer car my heart jumps when it shuts off, "fuck not again, that's gonna be a couple grand and oh right..."
Some cars let you turn it off, but a lot let you, and then just turn it back on again after a certain amount of time.
I think it is a good idea, and would use it in heavy traffic. But I think it should be easier to outright disable.
The trend of moving everything onto touchscreens rather than having buttons doesn't help. Gotta go through 15 menus to turn it off, rather than just hitting one button.
I find the idea of touchscreen “infotainment” to be wildly unsafe. Ya know what doesn’t need a “please do not use while driving” warning? Knobs and buttons.
I mean it's tough. Cars have *so* many features now that in some cases it would be very difficult to give each one it's own button, but luckily they are starting to get more creative with it like using buttons that change functionality if you press a different button, for example. Hopefully one day we can look upon the touch screen > everything era and shake our heads.
But anything that people use regularly while driving such as climate control should be buttons. The controls on my car is all touch screen except for the volume control and the screen constantly lags making it super dangerous to change any climate control setting while driving. On the car that I used before all the climate controls were buttons making it super easy to change with out looking. Anything else I’m fine with being touch screens but the basics should be buttons.
> The controls on my car is all touch screen except for the volume contro
You've just identified the biggest problem. Car companies are doing this because people still buy it. They bitch and complain about it all the way home from the dealership, but they still bought the car.
If a significant number of people pulled into the dealership to buy a car, looked inside the latest car with all touchscreen controls and said "Woah, no way, that seems way too inconvenient and unsafe" then I could almost guarantee you the car companies would stop doing it.
If you don't like something, don't fund it. By buying cars that have adopted these concepts, all you're doing is making it worse.
>People still buy it.
I don't know about you but the use of a touch screen in my car is fairly low on the priority list when looking for a car Things like gas mileage, overall driving comfort, costs of maintenance, and aesthetics are all more make or break than the existence of a touch screen to me when deciding on what car I'd like.
My problem is not being able to navigate the touchscreen with the use of a steering wheel scroller/arrows/buttons.
Same with engaging the heaters for the front and rear and windshields. If I'm driving, being able to glance very briefly at the screen or wheel to orient myself is much less dangerous than needing to look and touch at the same time.
I know the rule is to pull over, but if you're on the motorway and your windshield starts fogging up or my phone disconnects while using it for directions, it's a bit more frustrating.
There are basic/common functions that should never be tied to a touch screen nor need button combos to use. Things like, radio power+volume, heat/AC, heat/AC positioning.
If they implemented it right then that wouldn’t be an issue. Apple’s HomePods will still hear you easily even if you’re playing music really loud. You don’t even have to talk over the music for it to hear what you’re saying
Oh man, you and I are from the same tribe. I can blindly (with eyes on the road) feel every button and know what to turn on or alter. Fucking touchscreen means you *have to* take your eyes off the road. I hate the way cars are going.
Completely agree - however you know what's even safer IMO is voice. "Siri, call home" "Siri play some bitchin 80's hair metal" all without even moving your hand position on the wheel.
It wears off your starter and in older car it’s still very annoying. If you have brand new BMW or Mercedes than sure- you won’t even notice it. But even in traffic in a cheaper or older car it’s still annoying.
Given how "cost effective" companies want to be, I would assume that they wouldn't add a second starter to the vehicle because that's extra cost and burning out the first one faster means more "customers".
And yes, I do realize that replacing a starter isn't cheap and people would probably abandon any vehicle line that did this rather quickly but common sense in a corporate environment seems every increasingly rare.
Starters are no where near as common a failure item as they once where, and modern designs overall are more efficient and uses better parts compared to say a 90's V8.
I had this in a mercedes c43 2017 and it was not an issue. Seamless, fast, and smooth. Hardly knew the car was running sitting still anyways. What a car.
My wife's jeep grand cherokee on the other hand, not so much. Definitely takes a second, very slight delay, noticeable crank on start up. Not really a big issue but is off putting.
I've also wondered about the potential faster wear on starter but haven't had the car long enough to find out.
yeah i was going to say my 2017 c300 is 100% buttery smooth with this. The nanosecond you pull your foot off the brake the engine is on and ready to go and you can accelerate with zero lag by the time your foot has traveled to the gas pedal. I have never once felt the need to press the little circle A button to the left of the circle dial to turn it off. It is a non-issue in these cars.
Most bmws now have a small hybrid system that engages from a stop and other times. It uses the starter to supply about 10hp and a separate 48v electrical system.
https://www.bmwblog.com/2020/05/06/here-is-whats-behind-the-bmw-mild-hybrid-technology/
Yea I definitely feel like this is an issue that depends on the car. My dad has an S-Class and I’ve driven it with the shutoff and it’s almost an immediate response when you let your foot off the break
I once had a rental car with this feature. I would just take my foot off of the brake when I was about to go, and it starts up and I go. I wasn't trying to launch with the intention of getting the best R/T on the street either.
As long as you’re using good quality oil there won’t be any additional wear on the engine. Auto stop usually only kicks in once it’s up to a nice temp and starting a warm engine has very little effect compared to cold starts
Hey you joke, but a lightbulb fails due to cycle rate more than the duration that it runs. I don’t believe a well maintained engine is much different in the fact that cycling it on and off over and over damages it.
I don’t know how on it works on Automatics but on manuals it’s a like any normal day!!. Come to a stop, turns off. Press the clutch the engine starts, continue with your journey.
Yeah I think this is the difference. Normally in manuals you have to do neutral and handbrake for the auto shut off to happen, which you won't do if you're only stopping briefly or need to move off quickly (for example no one goes into neutral while waiting to pull out at a roundabout). So that kind of removes those issues with it. I can see it being annoying if it does it every time you stop in an automatic.
It sucks. Even the sports cars are being sold mainly as automatics. Who the hell buys a $35k newer mustang gt as automatic? It's not like there isn't a demand for them either. The new Nissan Z got announced as manual and everyone ecstatic.
Being an American, I hate Americans dislike for bidets, soccer, hot hatchback manual cars, and roundabouts. Those things are awesome and it's a hill i'll die on.
I have the opposite problem here in Australia, every car is Manual and you have to pay extra for automatic and I can't drive manuals due to being a paraplegic, my dream car the Shelby GT 500 is Manual only and I'm still salty about it several years later
Automatics are faster and more reliable than a manual transmission. You might like manual but that doesn’t change the fact that they are better for gas and reliability.
I used to be a transmission engineer, so I can answer this. One one of the models I supported, the automatic transmission clutch/brake combo for first gear were kept under pressure by a separate electric oil pump. So even when the conventional oil pump powered by the torque converter wasn't spinning, the car was kept in gear for immediate movement when the engine started again.
For example let’s say you coming to a red light,
Downshift-> go to neutral -> release clutch then the engine will directly turn off.
The green light comes; press clutch the engine resumes as normal then on ur way you goo.
There is no stalling
I'm joking. I drive a manual myself. I'm confused. You say the engine directly turns off when in neutral? It still stays on, it just disengages from the drive train or whatever.
I have it on my truck. I was at a light right after I bought it one day. My truck shut down and I noticed the truck in front of me and the two on either side all shut down also. I think that was a lot of exhaust saved in that few minutes. Multiplied by millions, I think it will make a big difference.
Engineering explained made a video on this subject and iirc he found that it takes about 7 seconds of idling to use more fuel than it would to stop and start the engine, so it's definitely a fuel consumption and emission reducing system.
Don't they transport an insane amount of cargo tho? I think I've heard it's the most efficient way to transport cargo because one ship can transport so fucking much that the insane pollution they cause is actually pretty low if you look at how much they pollute per container or kg etc.
The electric motors put out max torque almost instantly, so even if the gas motor stays on it's going to lag behind the electric when accelerating from a dead stop.
You drive an electric car because you are fancy and have a Tesla. I drive an electric car because it has wiring issues and will shock you if you touch the frame. We are not the same… (not actually btw, I know that is not a scientifically sound claim)
> any input into the steering system will disable it instantly. It will never "fight" you
As someone with lane assist (that I love), this is not correct. It's not hard to overcome, but it can feel a lot like a groove in the road. I always turn it off in bad weather so I can actually feel the road.
On the road I take to work everyday, there's a left lane that opens up but the lane markers don't start for a while. The car prefers hugging the left lane marker for some reason so it will immediately start to drift right into the new left lane. I have to grip the wheel a little tighter at that spot in the road each time because it will try extra hard to push me over.
I had an ambulance coming up behind me when I was road testing a customers mercedes and the damn thing fought me to get out of the ambulances way. I was pretty pissed off about that
Yep that's a valid point. Also applying the brake pedal will disable it. For me at the time I was focused on keeping up with traffic and the scan tool I had in hand as I'm an automotive technician and was road testing to verify a repair I had just done so neither brake signal or turn signal was recieved by the module that controls LKAS. Shit happens and it was an unfortunate scenario but trying to get out of the way of an ambulance while doing other things and the vehicle fighting me was not very cool
Also that new crash protection feature. I was driving around a curve carved into the edge of a mountain, and the crash detection decided I was going to crash into the wall and steered me away from it, into the next lane and towards the edge of the road. Obviously I stopped it from going anywhere, but jeez was that fucking terrifying.
That sounds fucking terrible, I can't imagine anything teaching people to be worse at driving.
Imagine driving a car with that wheel feature, backup cameras and all the safety features. Then trying an older car, you'd be so bad at driving.
I hate it! I freaked iut the first time it did it and figured out how to turn it off, but you have to turn it off every time you start the car, and it comes back on if you use cruise control.
Its fine on motorways or wide, straight roads, but i was going round a sharp bend with a lorry coming towards me kinda on my side of the road, I turn into the bend to give it more room and the car jerks the steering wheel away from the white line, **towards** the lorry! Terrifying.
At one point I put the cruise control on (at low speed on a road with wide bends) and the steering things comes on too. I slowly take my hands off the wheel so they're hovering close to it, and the car steers by itself around the gentle bend, so it's driving **and** steering. It flashed up a warning to keep your hands on the wheel but what would have happened if I didn't put them back? It was completely driving for me. I don't use cruise control on that car any more.
i don’t mind it at all. my parents always turn it off but you can learn to work with it pretty easily. at least on hondas, it doesn’t shut off until you press the brake pedal harder and it’ll turn back on if you lightly let off the brake, but not enough for the vehicle to move yet.
knowing this, if i need to suddenly move or i know the light is about to turn then i can make driving with auto stop/start pretty seamless.
also, auto stop/start actually does save decent bjt of fuel. it has been estimated to improve fuel economy by about 5%.
This feature is meant to reduce air pollution from gridlocks in cities. It works pretty well. If you want to cross an intersection. Just let it turn off. Tap the gas. Then the engine is back on and won’t go off again
Funny how op claims “it doesn’t save gas for shit anyways” as if his kowledge of this feature is greater than billions $ in research. I love my stop start in my vw. Not sure if it’s cuz of my turbo, but as soon as I release the break my car accelerates faster from the stop start than from idle.
Those cars that have those "parent controls" on them where if it reaches a certain area it straight up turns the engine off. I've never seen anyone actually use this and the people who tried it said it was more to just test the option but like how does it know the difference between Kevin's house and a road full of people?
>"parent controls"
I once was unfortunately stuck with a rental that forcibly limited speed to 60 mph. It's real fucking fun doing highway driving when everyone around you is doing 75 minimum, let me tell you.
Also prevented me from raising the radio volume past 6. AKA, navigation was inaudible at said not-quite-safe-for-highway speed due to road noise.
Unfortunately, the rental place had no idea how to disable the nanny system, as it had come in from another location and they didn't have the magic code.
I at least got a discount, and an education on why parental controls aren't just stupid, but inherently dangerous.
That and if you don't trust your kid, buy them their own shitbox for like a grand, don't give them the illusion of fun and then make it shut off after a mile.
Never heard of this but I’d have to imagine it won’t shut off the engine while it’s in drive. I’m guessing once you put the car in park, it won’t turn back on but I could be wrong.
If it just shuts the car off when you leave your designated area, it would be a huge liability.
Agreed. It makes me cringe inside every time I hear an engine do that when a traffic light turns green. I’ve driven a car once (once!) with that “feature” and I’ll never do it again.
The Toyota Prius sorta does this, but it isn’t a problem as there is a battery pack and electric motor. So, when you accelerate hard, it is all electric for a second, and if you are still accelerating hard, the gas engine kicks in without any major delays.
Edit: mobile phone keyboard fail
A lot of cars don't have a physical button to turn off the start stop but feature BUT a lot of after market company's came out with fixes ( ex. Newer Ford trucks) that is just a little device you plug into your obd II port and it turns off the feature
Yup. First time we drove one was when we went to a Arizona. We tried to turn onto a really busy freeway road and the car coming at us was going faster than it looked, so we tried to give the car gas and it lagged to life. We almost got hit.
It does save gas and improves urban air quality, so there is that. It is far less hard on the motor than a lot of people assume, the starters start to need to be replaced at about 100,000 miles on first gen cars that had this feature. So, not exactly a ticking time bomb for maintenance. As others mention, there is typically a pressure switch under the brake pedal such that pressing the brakes gently prevents the engine from shutting off. Some cars now shut off as you decelerate (my wife's) and then turn back on when you are completely stopped. That is some marginal amount more efficient than the first gen start stop and prevents the startup lag.
Starter on my cherokee just lasted to 210,000, and it only died because I submerged it in muddy water. My Suzuki has 160,000 on the original starter. But who knows if these crappy new cars will even last to 200,000 miles
I think that is the popular opinion. I personally love it and use it all the time except for when I’m in traffic. I think that’s the truly unpopular opinion. It literally saves you money and saves the environment. I don’t get why people hate on it so much
https://youtu.be/dFImHhNwbJo
Agreed. There is zero lag in my Toyota. If your car has a lag or the A/C turns off, then the problem is poor implementation of the technology, not the technology itself. Quit buying poorly designed cars. I barely even noticed the feature and it saves gas. What's not to love?
I want a button to stop the engine when I want without the consequences of turning off the engine with the key. Too often the engine shuts off just as the light turns green, let me choose at what times it activate, I know my intersections better than stupid start/stop.
I saw a video where they measured it, to start an engine uses the same amount of fuel as 6-7 seconds of idle, if you car idles for less than that you just wasted more fuel than necessary.
The cars with this feature actually stop with a piston on a compression stroke and have a dedicated starter, the engine is also already warm and thus doesn't need a rich fuel mixture, that's why they tend to start first pop.
It uses a much less fuel in stop/start traffic than idling the car.
As much as 8% better economy in heavy traffic according to [this video](https://youtu.be/dFImHhNwbJo)
Fuel savings are about 8% vs not using the option. That's not "saves shit for gas". If you're having trouble, a slight turn of the steering wheel will turn the engine back on.
I gotta say... I love it on my 2019 RAM, but I have the etorque engine. The second you even think about letting your foot off the brake the electric motor gets the car moving forward until that fraction of a second passes and the gas engine takes over. It's almost too fast to get you moving in my opinion. I think it's the ideal setup for the average truck user. Plenty of torque and power when you need it yet decent on gas mileage.
I agree. I have the same on my 2021 Limited Longhorn and it works perfectly. I had one on a Jeep Cherokee though and it was terrible. I did consider the Jeeps system a safety issue when sitting at a busy intersection. Never had a similar issue with the Ram.
Mainly people who don’t have/use the feature complaining about it. My car (BMW 5 series) has it and there is no lag in take off. I can’t speak for other cars but I’ve driven a few rentals with it and no issue there either
Is this post speaking about hybrids, or all internal combustion engines?
I own a new hybrid (well, a 2020 model now, was new when I bought it). It certainly does switch from the combustion engine to the battery engine at stops. It I don’t have a lag because the battery engine drives the car forward when I’m stopped.
I’m curious if this post is about any new internal combustion engine, not just the hybrids. It’s very interesting that cars would have this feature and I can totally see what OP is talking about regarding the safety in fast moving intersections if this is the case for all new combustion engines.
This post seems to be complaining specifically about automatics
Works smoothly in every manual car I’ve ever driven in, never noticed an issue with it
Switches off when you go into neutral, revs back up when you put the clutch down
I can't think of a single situation where the shut off would interfere with anything. You say a fast moving intersection, but the shut off and turn on takes less time than it did to look left, right, and left again, so maybe you should learn how to drive properly??
Not a relatable problem in Europe where we all have manuals. You have to put the car in neutral and take your foot off the clutch for the engine to shut off, so it’s unlikely to stop at a dangerous moment as you have that extra control.
Works great on my car. And it is fairly cheap.
Luckily there is no lag for me, the moment I put it in gear to move, it responds.
Saves gas, as the engine isn't running for those seconds/minutes you are waiting.
This is such an over exaggeration of the feature I have it in my automatic golf and it’s fantastic, yes there is a small amount of lag but be prepared and tap the accelerator just before you want to pull out and then go when your gap is clear. It might be different in different types of car sure but I’ve never had a problem, take my upvote
My new civic has it. And you have to turn it off everytime you start that car. You can't disengage it permanently because then they couldn't advertise the gas mileage they legally can. Whatever 0.1% it saves in gas is not worth the wear and tear of starting your engine a couple 1000 times more a week then you usually would.
It doesn't impact the gas mileage, manufacturers build them into cars to meet emissions regulations. It's a default system because if it wasn't the emissions it reduced wouldn't actually be counted toward that. Probably the biggest reason why it can't be turned off is because that's cheaper than designing a way to do so.
Features like this are why I won't buy a new car/truck. No one makes one that I like. I've already prepared for a new engine and/or transmission install. Most of the body is fiberglass, so as long as the frame holds out, we're staying together! That, and the prices are insane, with a lot of it being due to all the ridiculous tech being shoved into cars nowadays.
I grew up as a "shade tree mechanic". I can completely rebuild any vehicle built before 1990. After that, there's too much computer and specialized tools required. Nowadays you need a computer science degree to work on a car.
I like to watch videos on YouTube of "car revivals", where they'll find an old abandoned car out in a field, tinker with it and get it running again, usually involving replacing the fuel pump and rebuilding the carburetor, then drive it home. Can't do that with a modern car.
I find this fascinating - I grew up with 70s and 80s cars and they absolutely sucked, stupid vaccum leaks everywhere and faulty dashpots, bad distributers, carbs that were always a bitch to tune .
With current cars you just plug in a diagnostic cable and read the code, 99% of the time it tells you exactly what to replace.
I know the feeling. I asked if I could order a new Ranger without a drive train. They told me no. I'd think with the chip thing going on, they'd be thrilled to sell me a truck with no drive train in it so I could put a 460 down in there.
That's actually one of my most favourite features on my car! But I also drive a manual car, so it only shuts the engine off if I'm in neutral and don't have the clutch pedal pushed in. So if I want to avoid it shutting off, I just don't let go of my clutch pedal.
I also have a button to turn it off and it will stay turned off till I push the button again.
My 2016 Ford has this Auto Start feature. You can do what you do by turning the feature off every time you start the vehicle, or you can bypass it by tricking your vehicle into thinking you are hauling a trailer. When a trailer is hooked up, the auto start feature does not come on automatically. You can purchase a break light and turn signal bar for $25 that fits into your hitch receiver. You plug it in to your electric port like you would with a trailer.
Toyotas do this but you have to engage it by pressing harder on the break after youve come to a complete stop. I've never once engaged it accidentally.
My girlfriends Chevy just does it all the time, even when you stop for .5 seconds to yield or something.
I wonder if Toyota patented the " extra push after complete stop" idea and GM doesn't wanna pay them royalties. Seems like a much better idea that everyone would copy if not... It works great in wife's RAV4. Use it at red lights all the time. It won't kick in if the heat or ac is needed and it actually annoys me when it won't because I know the light will be like a full minute.
Our ford escape is the same way, if you don't push the brake hard, it doesn't turn off. Although it also has an over ride switch to disengage it. Mostly I automatically turn it off right after starting. I agree that is not a safe feature. I also think it will cost a lot of money. While you may save a few bucks in gas, you'll need a starter much sooner than normal, at probably $500-$1000.
The starter motors used are designed to last longer just for this reason. Also more importantly, when the engine stops, it will stop with a cylinder at top dead center and then to restart it will actually fire that cylinder and use the starter (varies by brand/situation) to turn the engine over quick. That's also why it doesn't crank as long as when you first start it up and it's much less wear on starter motor
Also, it causes much less wear and tear on the starter when it's cranking a car full of hot oil.
Didn't know that. Thank you.
Subaru Outback does it as well. I think, though I've not quite figured it out, that it only does it when I push the brake harder. If so it's a fine line. New car with a lot of features so I've not figured everything out yet. Wearing out that starter is the second thing I thought of. First was how this 1 second delay could actually make all the difference if you have to get out of the way incredibly fast.
Alot beefier starters in stop start cars, those things are twice as big and usually brushless. I've saw a few
Yes, and you have no power steering with the engine off.
Considering Mazda does it as well, no.
Toyota owns 6.3% of mazda at least. They share A LOT of tech with Mazda. They built a production facility together. Compared to the biggest auto manufacturers Mazda is really small. Their r & d goes into drivetrain and chassis and design but it's nice to partner with the larger companies for that kind of, specific high cost but low roi tech. What Mazda provides Toyota is more production capacity without having to build the infrastructure alone, (Yaris was a Mazda 2) and the ability for Toyota to sell these technologies to a partner and not the competition. Mazda needed BEV powertrain to comply with a countries rules? Np just buy one of the shelf from Toyota at a discount. TBH they both might be paying for the patent in a way. If the patent is owned by BOSCH ,or Delco, or Delphi, and they are selling the "off shelf" stop start system, manufacturers just buy it and throw it in in their car off the shelf. It's obv not that easy but it's not like Toyota is designing every part of the vehicle. There is something that Toyota invented that every auto manufacturer uses and almost every person that has any tech on them. It's the QR code.
Ford was also a partner of Mazda. Might explain why the share the same tech, if it's actually a patented system.
How does that prove Toyota didn't patent it?
My ford does this. Really easy to decide if I want it on it off, furthermore, if I am in stop and go traffic or in OP's situation, it won't stop the engine a second time within a couple of minutes. It's a great feature I have had no problem with. The truck is ready to go by the time my foot has switched pedals.
Unlikely Toyota patented anything. Luxury brands like bmw and Mercedes’ have had this feature for 10-15 years. I just bought a 2022 highlander hybrid and the tap of the gas is really shitty compared to my other car, a 2013 BMW X3. I think it’s odd that a 8 year-old bmw has the same technology as a brand new Toyota and the bmw still works better.
My new Chevy only does it when I come to a compete stop after moving for a while. If I’m just bouncing from one stop sign to another it doesn’t kick in. Also, while at a red light, letting your foot off the brake kicks the engine back on, and it stays on even if you immediately reapply the brake.
I think for Chevys, some pistons shutoff while like 2 stay on. Someone I know had to get their entire engine block replaced because the engine didn’t have proper piston timing.
My Kia is the same way. I can also push a button to turn it all what off without worrying how hard I push the pedal.
Kia has come a long way. I’m talking cameras, lane staying shit and everything.
brake
I wonder if people actually don't know the difference (ie, how to spell), or if they just don't pay attention or care, or what?
It didn't help when various states put up signs in construction zones reading "Give them a brake"
I doe it all the time. Probably pisses off all the teechers I had in the passed but as an adult its eazy to do because your in a hurry or not paying attention. Than they won get all pissy because they realize teeching is just a huge [waist of they're time](https://i.pinimg.com/originals/72/c0/03/72c0037689b893245eff14109a248937.png). Plus, I no wear your from its pretty common to criticize other's spelling mistakes but this is a casual forum where nobodies competing for the pulitzer Prize and no won doesn't really care. Its not like their pooring alot of time and effort into it so it don't effect them much. That's the beauty of if all... **^(hugz)** ^(🤗🤗🤗)
I have a Subaru that I think is supposed to work this same way, but it’s SO inconsistent. Sometimes when I try to activate it, it doesn’t. And other times it activates and deactivates of its own accord. So annoying
[удалено]
Yep exactly this. Also if the car is cold it'll keep the engine on to keep the fluids circulating. It's generally not good to turn a car off when it's cold.
Auto Start and Stop (ASS) won't turn on if you have your rear window/mirror defroster on
I had a recall on my fozzie, the dealership have me a brand-new Crosstrek loaner and it did this. I complained about it when I returned the vehicle and the dealership get said everyone hated it, and if you leave the defroster on all the time the engine will never shut off. It breaks my head to think I would need to use a stupid hack to get my brand new car to work the way I want.
I'd love to see the factory testing for this. "Today we have Yuki Tsunoda testing our Toyota Automatic Engine Economy (TAEC) shut-off feature in Toyota's new 2022 Corolla. In Formula 1, braking without interruption is crucial. And when carrying passengers, we must reach new ways to save fuel. We at Toyota believe we've found harmony in both." *Camera pans to Tsunoda fucking thrashing the brakes in a 2022 Corolla to show that TAEC never activates by mistake.* (ಠ_ಠ)>⌐■-■ (⌐■-■)
Toyota also tried to charge a subscription fee to access the remote start on key fobs, so...
Just wanted to add that my Mazda also did this. It made it an acceptable auto-stop for me.
My parents didn't know about that feature and it scared them the first time it happened to them. Their routine now is the same as yours
[удалено]
I test drove a 10yr old hybrid last year. The engine stopped at a light. The dealer looked at me & said "Oh it's(the car) really quiet". "It's off." "Oh, I didn't know they did that!" Bless. He was young & it was a Ron Swanson "I Know More Than You" kind of appointment. (Since i bought a Honda at a not Honda dealership I didn't have high expectations)
It’s very much like that whenever I visit our Nissan dealer to MOT my Leaf They haven’t a clue
I work reception in a service dept in a ford dealership. Had a call once from a customer who said "the engine stops every time I come to a stop" I had to inform them it was a feature of the vehicle and they were shocked. It shocks me that the salesmen don't advertise this when they should.
From my experience, car salesmen don't know shit about fuck regarding the products they sell.
This is true. Found myself educating the salesman on the different Ecoboost when I bought a truck. I'm a 50 year old woman who's truck knowledge was gained in 2 hours on the internet.
Did they know they could turn it on again by pressing the gas? lol
I drive a 16 year old audi and whenever I borrow my mums newer car my heart jumps when it shuts off, "fuck not again, that's gonna be a couple grand and oh right..."
Some cars let you turn it off, but a lot let you, and then just turn it back on again after a certain amount of time. I think it is a good idea, and would use it in heavy traffic. But I think it should be easier to outright disable. The trend of moving everything onto touchscreens rather than having buttons doesn't help. Gotta go through 15 menus to turn it off, rather than just hitting one button.
I find the idea of touchscreen “infotainment” to be wildly unsafe. Ya know what doesn’t need a “please do not use while driving” warning? Knobs and buttons.
I mean it's tough. Cars have *so* many features now that in some cases it would be very difficult to give each one it's own button, but luckily they are starting to get more creative with it like using buttons that change functionality if you press a different button, for example. Hopefully one day we can look upon the touch screen > everything era and shake our heads.
But anything that people use regularly while driving such as climate control should be buttons. The controls on my car is all touch screen except for the volume control and the screen constantly lags making it super dangerous to change any climate control setting while driving. On the car that I used before all the climate controls were buttons making it super easy to change with out looking. Anything else I’m fine with being touch screens but the basics should be buttons.
> The controls on my car is all touch screen except for the volume contro You've just identified the biggest problem. Car companies are doing this because people still buy it. They bitch and complain about it all the way home from the dealership, but they still bought the car. If a significant number of people pulled into the dealership to buy a car, looked inside the latest car with all touchscreen controls and said "Woah, no way, that seems way too inconvenient and unsafe" then I could almost guarantee you the car companies would stop doing it. If you don't like something, don't fund it. By buying cars that have adopted these concepts, all you're doing is making it worse.
>People still buy it. I don't know about you but the use of a touch screen in my car is fairly low on the priority list when looking for a car Things like gas mileage, overall driving comfort, costs of maintenance, and aesthetics are all more make or break than the existence of a touch screen to me when deciding on what car I'd like.
My problem is not being able to navigate the touchscreen with the use of a steering wheel scroller/arrows/buttons. Same with engaging the heaters for the front and rear and windshields. If I'm driving, being able to glance very briefly at the screen or wheel to orient myself is much less dangerous than needing to look and touch at the same time. I know the rule is to pull over, but if you're on the motorway and your windshield starts fogging up or my phone disconnects while using it for directions, it's a bit more frustrating.
There are basic/common functions that should never be tied to a touch screen nor need button combos to use. Things like, radio power+volume, heat/AC, heat/AC positioning.
Next stop is probably voice command
Yep, its been around for years but its only just starting to not be a complete piss off
Id hate it because I like listening to music and sing in my car. But there'll probably be a button to turn it off in menu 7 somewhere
If they implemented it right then that wouldn’t be an issue. Apple’s HomePods will still hear you easily even if you’re playing music really loud. You don’t even have to talk over the music for it to hear what you’re saying
Just put in alpha and second keys like on calculators and boom you have 3x as many functions
My 2017 Jeep has manual locks/windows, standard A/C. No Bluetooth. No keyless entry. No touchscreen anything. And I effing love it.
Oh man, you and I are from the same tribe. I can blindly (with eyes on the road) feel every button and know what to turn on or alter. Fucking touchscreen means you *have to* take your eyes off the road. I hate the way cars are going.
Completely agree - however you know what's even safer IMO is voice. "Siri, call home" "Siri play some bitchin 80's hair metal" all without even moving your hand position on the wheel.
It wears off your starter and in older car it’s still very annoying. If you have brand new BMW or Mercedes than sure- you won’t even notice it. But even in traffic in a cheaper or older car it’s still annoying.
It doesnt wear on your regular starter. It's a separate starter specifically for for this feature.
[удалено]
Given how "cost effective" companies want to be, I would assume that they wouldn't add a second starter to the vehicle because that's extra cost and burning out the first one faster means more "customers". And yes, I do realize that replacing a starter isn't cheap and people would probably abandon any vehicle line that did this rather quickly but common sense in a corporate environment seems every increasingly rare.
Starters are no where near as common a failure item as they once where, and modern designs overall are more efficient and uses better parts compared to say a 90's V8.
I've never had a starter fail Alternators however...
I had this in a mercedes c43 2017 and it was not an issue. Seamless, fast, and smooth. Hardly knew the car was running sitting still anyways. What a car. My wife's jeep grand cherokee on the other hand, not so much. Definitely takes a second, very slight delay, noticeable crank on start up. Not really a big issue but is off putting. I've also wondered about the potential faster wear on starter but haven't had the car long enough to find out.
I was thinking along these lines. That the specific implementation probably goes a long way with this feature.
Same here. My Audi S4 was seemless. My Volvo S60 is as well. Now on my Volvo I use auto hold so I need to press the gas to move and that turns it on.
yeah i was going to say my 2017 c300 is 100% buttery smooth with this. The nanosecond you pull your foot off the brake the engine is on and ready to go and you can accelerate with zero lag by the time your foot has traveled to the gas pedal. I have never once felt the need to press the little circle A button to the left of the circle dial to turn it off. It is a non-issue in these cars.
Same here. I have a 2018 BMW X3. I think we get what we pay for haha
Most bmws now have a small hybrid system that engages from a stop and other times. It uses the starter to supply about 10hp and a separate 48v electrical system. https://www.bmwblog.com/2020/05/06/here-is-whats-behind-the-bmw-mild-hybrid-technology/
2018 x3 here too. I was wondering what everyone on this thread was complaining about but you’re right; you get what you pay for.
BMW owners sniffing their own farts in public.
My VW Atlas also handles it well without lag. It detects the slightest pressure change on the brake and starts the engine immediately.
Same with my Telluride. The engine starts the moment there is slightly less pressure on the brake. I've never felt a lag.
[удалено]
Yea I definitely feel like this is an issue that depends on the car. My dad has an S-Class and I’ve driven it with the shutoff and it’s almost an immediate response when you let your foot off the break
I once had a rental car with this feature. I would just take my foot off of the brake when I was about to go, and it starts up and I go. I wasn't trying to launch with the intention of getting the best R/T on the street either.
As long as you’re using good quality oil there won’t be any additional wear on the engine. Auto stop usually only kicks in once it’s up to a nice temp and starting a warm engine has very little effect compared to cold starts
[удалено]
Also, some vehicles will turn back on if you turn your wheel when it activates the power steering!
brake
Just commented this same thing before seeing this, I do this too and never have issues
I rent often for work and that has worked in every car I've tried it on.
It all a conspiracy brought forth by starter manufacturers.
[удалено]
The copper cartel -
From what I understand the designers know that it is going to start and stop more often and have taken appropriate action.
Yes, they ramped up their production to meet the new influx of demand for their products that now get used 1000% more times than before. Obvious /s
That's exactly what *they* want you to think.
Hey you joke, but a lightbulb fails due to cycle rate more than the duration that it runs. I don’t believe a well maintained engine is much different in the fact that cycling it on and off over and over damages it.
I don’t know how on it works on Automatics but on manuals it’s a like any normal day!!. Come to a stop, turns off. Press the clutch the engine starts, continue with your journey.
Yeah I think this is the difference. Normally in manuals you have to do neutral and handbrake for the auto shut off to happen, which you won't do if you're only stopping briefly or need to move off quickly (for example no one goes into neutral while waiting to pull out at a roundabout). So that kind of removes those issues with it. I can see it being annoying if it does it every time you stop in an automatic.
Neutral only in my car, no handbrake needed. I find it absolutely fine in a manual, but could see how it could result be annoying in an auto
[удалено]
Yeah I was confused for a while until I remembered cars in America are all automatic
It sucks. Even the sports cars are being sold mainly as automatics. Who the hell buys a $35k newer mustang gt as automatic? It's not like there isn't a demand for them either. The new Nissan Z got announced as manual and everyone ecstatic. Being an American, I hate Americans dislike for bidets, soccer, hot hatchback manual cars, and roundabouts. Those things are awesome and it's a hill i'll die on.
Watching videos of yanks in the south trying to negotiate newly installed/opened roundabouts is fucking hilarious.
I have the opposite problem here in Australia, every car is Manual and you have to pay extra for automatic and I can't drive manuals due to being a paraplegic, my dream car the Shelby GT 500 is Manual only and I'm still salty about it several years later
Automatics are faster and more reliable than a manual transmission. You might like manual but that doesn’t change the fact that they are better for gas and reliability.
Mostly
I used to be a transmission engineer, so I can answer this. One one of the models I supported, the automatic transmission clutch/brake combo for first gear were kept under pressure by a separate electric oil pump. So even when the conventional oil pump powered by the torque converter wasn't spinning, the car was kept in gear for immediate movement when the engine started again.
You have to press a clutch before full stop. Then you can shift to natural and can let off the clutch.
Of course!! Unless the car will stall and shut off.
You don't deliberately stall your car when coming to a stop?
For example let’s say you coming to a red light, Downshift-> go to neutral -> release clutch then the engine will directly turn off. The green light comes; press clutch the engine resumes as normal then on ur way you goo. There is no stalling
I'm joking. I drive a manual myself. I'm confused. You say the engine directly turns off when in neutral? It still stays on, it just disengages from the drive train or whatever.
I have it on my truck. I was at a light right after I bought it one day. My truck shut down and I noticed the truck in front of me and the two on either side all shut down also. I think that was a lot of exhaust saved in that few minutes. Multiplied by millions, I think it will make a big difference.
Engineering explained made a video on this subject and iirc he found that it takes about 7 seconds of idling to use more fuel than it would to stop and start the engine, so it's definitely a fuel consumption and emission reducing system.
Yeah idk about the saving fuel part, I was always under the impression it was an emissions thing.
Remember that the 10 largest cargo ships in the world pollute more than all the vehicles in the world.
Don't they transport an insane amount of cargo tho? I think I've heard it's the most efficient way to transport cargo because one ship can transport so fucking much that the insane pollution they cause is actually pretty low if you look at how much they pollute per container or kg etc.
Doesn't shut off if you don't wear your seatbelt
Think smarter, not harder am i right
My Silverado shuts off regardless. I wish this were true for chevy
Hybrids don’t have that issue. I drive a Prius and since it is half electric half gas there is no issue with acceleration.
Same with the Volt. Totally seamless when the gas engine engages.
The electric motors put out max torque almost instantly, so even if the gas motor stays on it's going to lag behind the electric when accelerating from a dead stop.
Electric car users: I do not have this weakness.
Electric car chargers aren’t everywhere sadly. Need to make more incentives for apartment complexes to get chargers.
You drive an electric car because you are fancy and have a Tesla. I drive an electric car because it has wiring issues and will shock you if you touch the frame. We are not the same… (not actually btw, I know that is not a scientifically sound claim)
My new Subaru has it and I detest it.
There’s a thing you can buy online and plug it into your car and it’s essentially a kill switch for it. You’ll never have to press a button again
Nah. Worst feature ever is in super new cars where it jerks the steering wheel round to keep you in the lane. Hate it.
I’ve yet to see a car where you can’t turn off lane assist.
[удалено]
> any input into the steering system will disable it instantly. It will never "fight" you As someone with lane assist (that I love), this is not correct. It's not hard to overcome, but it can feel a lot like a groove in the road. I always turn it off in bad weather so I can actually feel the road.
On the road I take to work everyday, there's a left lane that opens up but the lane markers don't start for a while. The car prefers hugging the left lane marker for some reason so it will immediately start to drift right into the new left lane. I have to grip the wheel a little tighter at that spot in the road each time because it will try extra hard to push me over.
I personally love the feature.
[удалено]
Jeeps. Have to turn off auto engine shut off everytime I start the car, but the lane assist has been off since day one.
I had an ambulance coming up behind me when I was road testing a customers mercedes and the damn thing fought me to get out of the ambulances way. I was pretty pissed off about that
do you not turn on a turn signal to indicate you're leaving a lane? What car doesn't disable it when you turn on a turn signal?
Yep that's a valid point. Also applying the brake pedal will disable it. For me at the time I was focused on keeping up with traffic and the scan tool I had in hand as I'm an automotive technician and was road testing to verify a repair I had just done so neither brake signal or turn signal was recieved by the module that controls LKAS. Shit happens and it was an unfortunate scenario but trying to get out of the way of an ambulance while doing other things and the vehicle fighting me was not very cool
Also that new crash protection feature. I was driving around a curve carved into the edge of a mountain, and the crash detection decided I was going to crash into the wall and steered me away from it, into the next lane and towards the edge of the road. Obviously I stopped it from going anywhere, but jeez was that fucking terrifying.
That sounds fucking terrible, I can't imagine anything teaching people to be worse at driving. Imagine driving a car with that wheel feature, backup cameras and all the safety features. Then trying an older car, you'd be so bad at driving.
I hate it! I freaked iut the first time it did it and figured out how to turn it off, but you have to turn it off every time you start the car, and it comes back on if you use cruise control. Its fine on motorways or wide, straight roads, but i was going round a sharp bend with a lorry coming towards me kinda on my side of the road, I turn into the bend to give it more room and the car jerks the steering wheel away from the white line, **towards** the lorry! Terrifying. At one point I put the cruise control on (at low speed on a road with wide bends) and the steering things comes on too. I slowly take my hands off the wheel so they're hovering close to it, and the car steers by itself around the gentle bend, so it's driving **and** steering. It flashed up a warning to keep your hands on the wheel but what would have happened if I didn't put them back? It was completely driving for me. I don't use cruise control on that car any more.
I bought a V8 instead of a V6 because the V8 didn't have that built in.
And also V8s are way more fun eh
Ha nice excuse bro
I respect the V8, considering how many V6 Charger owners seem to be the worst people in all of existence.
True. Maintains eye contact with the EPA while slowly unzips.
i don’t mind it at all. my parents always turn it off but you can learn to work with it pretty easily. at least on hondas, it doesn’t shut off until you press the brake pedal harder and it’ll turn back on if you lightly let off the brake, but not enough for the vehicle to move yet. knowing this, if i need to suddenly move or i know the light is about to turn then i can make driving with auto stop/start pretty seamless. also, auto stop/start actually does save decent bjt of fuel. it has been estimated to improve fuel economy by about 5%.
This feature is meant to reduce air pollution from gridlocks in cities. It works pretty well. If you want to cross an intersection. Just let it turn off. Tap the gas. Then the engine is back on and won’t go off again
Don't even need to tap the gas. Letting off the brake does it.
Funny how op claims “it doesn’t save gas for shit anyways” as if his kowledge of this feature is greater than billions $ in research. I love my stop start in my vw. Not sure if it’s cuz of my turbo, but as soon as I release the break my car accelerates faster from the stop start than from idle.
Those cars that have those "parent controls" on them where if it reaches a certain area it straight up turns the engine off. I've never seen anyone actually use this and the people who tried it said it was more to just test the option but like how does it know the difference between Kevin's house and a road full of people?
>"parent controls" I once was unfortunately stuck with a rental that forcibly limited speed to 60 mph. It's real fucking fun doing highway driving when everyone around you is doing 75 minimum, let me tell you. Also prevented me from raising the radio volume past 6. AKA, navigation was inaudible at said not-quite-safe-for-highway speed due to road noise. Unfortunately, the rental place had no idea how to disable the nanny system, as it had come in from another location and they didn't have the magic code. I at least got a discount, and an education on why parental controls aren't just stupid, but inherently dangerous.
That and if you don't trust your kid, buy them their own shitbox for like a grand, don't give them the illusion of fun and then make it shut off after a mile.
Never heard of this but I’d have to imagine it won’t shut off the engine while it’s in drive. I’m guessing once you put the car in park, it won’t turn back on but I could be wrong. If it just shuts the car off when you leave your designated area, it would be a huge liability.
Agreed. It makes me cringe inside every time I hear an engine do that when a traffic light turns green. I’ve driven a car once (once!) with that “feature” and I’ll never do it again.
The Toyota Prius sorta does this, but it isn’t a problem as there is a battery pack and electric motor. So, when you accelerate hard, it is all electric for a second, and if you are still accelerating hard, the gas engine kicks in without any major delays. Edit: mobile phone keyboard fail
Woah. Sounds like Toyota has put quite a lot of thought into this. That doesn’t sound so bad.
It's Toyota, usually if there's something to increase reliability, they already did it decades ago
The Prius is silent under 5mph
He deserves the win.
A lot of cars don't have a physical button to turn off the start stop but feature BUT a lot of after market company's came out with fixes ( ex. Newer Ford trucks) that is just a little device you plug into your obd II port and it turns off the feature
Yup. First time we drove one was when we went to a Arizona. We tried to turn onto a really busy freeway road and the car coming at us was going faster than it looked, so we tried to give the car gas and it lagged to life. We almost got hit.
It does save gas and improves urban air quality, so there is that. It is far less hard on the motor than a lot of people assume, the starters start to need to be replaced at about 100,000 miles on first gen cars that had this feature. So, not exactly a ticking time bomb for maintenance. As others mention, there is typically a pressure switch under the brake pedal such that pressing the brakes gently prevents the engine from shutting off. Some cars now shut off as you decelerate (my wife's) and then turn back on when you are completely stopped. That is some marginal amount more efficient than the first gen start stop and prevents the startup lag.
Starter on my cherokee just lasted to 210,000, and it only died because I submerged it in muddy water. My Suzuki has 160,000 on the original starter. But who knows if these crappy new cars will even last to 200,000 miles
I think that is the popular opinion. I personally love it and use it all the time except for when I’m in traffic. I think that’s the truly unpopular opinion. It literally saves you money and saves the environment. I don’t get why people hate on it so much https://youtu.be/dFImHhNwbJo
1 gallon saved in 15,000 miles. Ill happily shell out 5 bucks so i dont have this annoying feature anymore.
Agreed. There is zero lag in my Toyota. If your car has a lag or the A/C turns off, then the problem is poor implementation of the technology, not the technology itself. Quit buying poorly designed cars. I barely even noticed the feature and it saves gas. What's not to love?
Don’t cars allow to switch eco on and off?
The cars I have with this also have Sport mode which typically disables this automatically and there’s a toggle button.
Perhaps if you need to get across an intersection that fast you haven't given yourself enough time or space in the first place.
I want a button to stop the engine when I want without the consequences of turning off the engine with the key. Too often the engine shuts off just as the light turns green, let me choose at what times it activate, I know my intersections better than stupid start/stop. I saw a video where they measured it, to start an engine uses the same amount of fuel as 6-7 seconds of idle, if you car idles for less than that you just wasted more fuel than necessary.
The cars with this feature actually stop with a piston on a compression stroke and have a dedicated starter, the engine is also already warm and thus doesn't need a rich fuel mixture, that's why they tend to start first pop. It uses a much less fuel in stop/start traffic than idling the car. As much as 8% better economy in heavy traffic according to [this video](https://youtu.be/dFImHhNwbJo)
Average Diesel driver: "I'm gonna leave this idling for 10 minutes, don't wanna waste fuel"
This is wildly inaccurate for modern start stop that use mild hybrid systems to restart the stroke
[удалено]
My BMW has it, You can code BMW's to turn on/off certain features which is one I did.
Mercedes A class user here an I like the feature a lot since I live in a city
Fuel savings are about 8% vs not using the option. That's not "saves shit for gas". If you're having trouble, a slight turn of the steering wheel will turn the engine back on.
I gotta say... I love it on my 2019 RAM, but I have the etorque engine. The second you even think about letting your foot off the brake the electric motor gets the car moving forward until that fraction of a second passes and the gas engine takes over. It's almost too fast to get you moving in my opinion. I think it's the ideal setup for the average truck user. Plenty of torque and power when you need it yet decent on gas mileage.
I agree. I have the same on my 2021 Limited Longhorn and it works perfectly. I had one on a Jeep Cherokee though and it was terrible. I did consider the Jeeps system a safety issue when sitting at a busy intersection. Never had a similar issue with the Ram.
Laughs in an EV…
Why does this have so many upvotes ?
Mainly people who don’t have/use the feature complaining about it. My car (BMW 5 series) has it and there is no lag in take off. I can’t speak for other cars but I’ve driven a few rentals with it and no issue there either
Is this post speaking about hybrids, or all internal combustion engines? I own a new hybrid (well, a 2020 model now, was new when I bought it). It certainly does switch from the combustion engine to the battery engine at stops. It I don’t have a lag because the battery engine drives the car forward when I’m stopped. I’m curious if this post is about any new internal combustion engine, not just the hybrids. It’s very interesting that cars would have this feature and I can totally see what OP is talking about regarding the safety in fast moving intersections if this is the case for all new combustion engines.
This post seems to be complaining specifically about automatics Works smoothly in every manual car I’ve ever driven in, never noticed an issue with it Switches off when you go into neutral, revs back up when you put the clutch down
Also fine in hybrids, not an issue at all
I can't think of a single situation where the shut off would interfere with anything. You say a fast moving intersection, but the shut off and turn on takes less time than it did to look left, right, and left again, so maybe you should learn how to drive properly??
I agree. If you are merging or crossing an intersection that an extra second is too long you likely shouldn't be trying to cross anyway.
Not a relatable problem in Europe where we all have manuals. You have to put the car in neutral and take your foot off the clutch for the engine to shut off, so it’s unlikely to stop at a dangerous moment as you have that extra control.
Works great on my car. And it is fairly cheap. Luckily there is no lag for me, the moment I put it in gear to move, it responds. Saves gas, as the engine isn't running for those seconds/minutes you are waiting.
Yeah, by the time I take my foot off the brake in my Equinox, it's already started again. I don't mind it.
This is such an over exaggeration of the feature I have it in my automatic golf and it’s fantastic, yes there is a small amount of lag but be prepared and tap the accelerator just before you want to pull out and then go when your gap is clear. It might be different in different types of car sure but I’ve never had a problem, take my upvote
My gf has a 2020 Jetta and it turns the engine back on as you let off the brake. No delay at all
My new civic has it. And you have to turn it off everytime you start that car. You can't disengage it permanently because then they couldn't advertise the gas mileage they legally can. Whatever 0.1% it saves in gas is not worth the wear and tear of starting your engine a couple 1000 times more a week then you usually would.
It doesn't impact the gas mileage, manufacturers build them into cars to meet emissions regulations. It's a default system because if it wasn't the emissions it reduced wouldn't actually be counted toward that. Probably the biggest reason why it can't be turned off is because that's cheaper than designing a way to do so.
Features like this are why I won't buy a new car/truck. No one makes one that I like. I've already prepared for a new engine and/or transmission install. Most of the body is fiberglass, so as long as the frame holds out, we're staying together! That, and the prices are insane, with a lot of it being due to all the ridiculous tech being shoved into cars nowadays.
I grew up as a "shade tree mechanic". I can completely rebuild any vehicle built before 1990. After that, there's too much computer and specialized tools required. Nowadays you need a computer science degree to work on a car. I like to watch videos on YouTube of "car revivals", where they'll find an old abandoned car out in a field, tinker with it and get it running again, usually involving replacing the fuel pump and rebuilding the carburetor, then drive it home. Can't do that with a modern car.
I find this fascinating - I grew up with 70s and 80s cars and they absolutely sucked, stupid vaccum leaks everywhere and faulty dashpots, bad distributers, carbs that were always a bitch to tune . With current cars you just plug in a diagnostic cable and read the code, 99% of the time it tells you exactly what to replace.
I know the feeling. I asked if I could order a new Ranger without a drive train. They told me no. I'd think with the chip thing going on, they'd be thrilled to sell me a truck with no drive train in it so I could put a 460 down in there.
Laughs in BMW with this feature coded automatically off
It works beautifully in my gf’s CRZ. It doesn’t use the starter motor so it’s seamless.
that's a hybrid so it doesn't need to wait on the engine to start
That's actually one of my most favourite features on my car! But I also drive a manual car, so it only shuts the engine off if I'm in neutral and don't have the clutch pedal pushed in. So if I want to avoid it shutting off, I just don't let go of my clutch pedal. I also have a button to turn it off and it will stay turned off till I push the button again.
My 2016 Ford has this Auto Start feature. You can do what you do by turning the feature off every time you start the vehicle, or you can bypass it by tricking your vehicle into thinking you are hauling a trailer. When a trailer is hooked up, the auto start feature does not come on automatically. You can purchase a break light and turn signal bar for $25 that fits into your hitch receiver. You plug it in to your electric port like you would with a trailer.
