I just got a car that shuts off when stopped. I hate it. Especially when you stop at a stop sign for a second too long and it shuts off then you hit the gas and it hesitates because it has to literally start the engine before moving.
There’s a button in mine that’s like an @ with a capital A. Have to push it every time I start the car, but it stays running until I manually shut off the car.
I have been renting a lot of cars lately. The hybrids do the best job because hybrid. The gas cars can be hit or miss. A jeep renegade I rented did ok except that sometimes it would auto stop, sometimes it wouldn’t. You had to be stopped and the. Push the brake a little harder to engage.
I have a Volvo and if you stop at a pace other than very gentle, it will shut off the engine before you’ve stopped moving. That one is annoying.
Got a newer Volvo as a loaner and the baby hybrid system in them is FAR better. You can’t even really hear it start up. I believe it doesn’t have a traditional starter, you hear almost nothing when you start it for the first time. It just kind of goes from being off to running without any sound or vibration. Very weird but kinda cool.
Each system is a little different, some are not very good, others you don’t even notice.
Two things: firstly, 48v integrated starter generator vs 12v starter. Secondly, newer cars I believe memorize where in the cam rotation they shut off so they can ignite almost immediately if the conditions are right.
My Toyota hybrid stop start is so seamless, I would not know I was on gas or electric power. It doesn’t even use a starter. Also, the entire car doesn’t have a single belt.
The starter in the mHEVs is about as powerful as the entire engine of the original Fiat 500. It entirely skips the *r-r-r-*revup of a normal engine start.
I have that hybrid volvo and it’s amazing, I never even think about it. It just works. If someone wants to test drive, it’s an automatic xc40 with b4 engine.
I bought a car in December that does this. Literally all you have to do is let off the brake wait half a second to 1 second and it starts right back up not a big deal. Just maybe you know have a slight bit of patience in your driving.
That feature never affected my driving at all and never bothered me at all. In fact I don’t think I ever remembered that it was a thing after the first week or two.
Depends very much on the car. My car has auto off and starts up the engine as soon as the car in front of me starts moving (it detects that with the parking and radar sensors).
Or if I just move the foot off the braking pedal the engine will be fully running as soon as my foot reaches the gas pedal.
It’s at 2017 Mercedes, at the time they already spent some effort into that tech, for example I have an electrical water pump that keeps up the circulation even during auto off and the starter is different so it can start the car even while starting to move.
The only moment I turn it off (ok switch to sport mode which turns autostop off) is when I want to race someone at the light in order to change lanes in front of them later.
I normal operation you don’t notice.
Ah and last year autostop did not work for a few months as my battery was old, the car noticed and refrained from stopping the engine until I got a new battery (It will also do if I need aircon or the motor is too cold or a number of other conditions)
I think its just a bad car. I have a volvo xc40 and it starts right away and takes off in less than a second. No hesitation. It’s a fuel car, not electric.
I’m guessing they have a bunch of oil squirters engineered into the design but seems to me that constantly letting oil drain into the crank case while sitting then firing up again is going to cause a short life for these engines.
I’ve only riden in two vehicles that have this idiotic feature but they could both be disabled after the initial startup.
Modern oils and modern cylinder lining makes this a non-issue.
You’re more likely to have a modern car with bad rings as they chase fuel economy numbers. Honestly, a hybrid is a very solid choice anymore. Lifts the burden of the gas engine having to be hyper-efficient and eases the extreme tolerances required to get there.
Shame that there are very few fun hybrids, crazy expensive things don’t count.
Infiniti made an m35h that actually had more power than the gas version and it got better mileage. Granted, it is a porky sedan, but that thing would still haul its fat ass.
Oil isn’t the problem, my car will turn on again before too much oil drains out of the engine and oil pressure sinks too low. Cooling is, interstingly, so they switched to an electric water pump for cooling - it will stay running during auto off so you don’t get too hot temperatures in the turbo for example. (4cyl 2l engine has a turbo)
There’s quite a bit of tech going into auto off since it first appeared. (Heh, my first car in 1989 had an aftermarket start stop switch to stop the engine at the traffic light - i never used it except once or twice for fun - still one cylinder exploded one day on the Autobahn)
I rented a Rogue in Vegas for a week. Every damned stoplight, ac slowly gets warmer, actually starts putting out warm moist air. Some of those longer lights out there were miserable.
I finally found the button and made it stay on and spent that extra $0.97 on not being miserable.

I haven’t seen one where this can’t be disabled as a setting. Assume you’ve checked? If not imagine someone has found a hack for this.

Lower right, under the radio tuning knob.

You must’ve gotten a good one.

Same, Honda CRZ (it’s like a Prius but it doesnt make you hate yourself) and I dont have any delay on quick-starting the engine.
It’s a hybrid but the electric part is just KERS, so I only fuel it up, I don’t charge it.

Stop-start is not about fuel economy, it’s about emissions. Idling is very dirty.
We’re defining fun very differently. My prius has ridiculous low end torque thanks to those electric motors.
Idling motors waste fuel and because the catalytic converter is not hot enough, pollute at huge levels.
What is idiotic is people who idle for hours.
