Drivers will get used to it, and it would be for the greater good of all makes of cars across the board. Consumers would only be glad and appreciative to be able to do their part by swallowing another kill-joy feature built into new cars.

Why would they deal with designing something like that when they can make the car hybrid and use electric motors for acceleration from a dead stop?

OK, you guys have somewhat eased my concerns about the long term effects (maintenance $$$) of stop-start. But what about AFM? Cylinder deactivation has caused a ton of problems, for example, just look at all the 5.3L guys on the GMT900 forums. Ask them how they feel about AFM.

It already has been. At least at GM. There are still some AFM applications available, but that’s more because it takes a while to turn over (4) engine plants that build variants of the 5.3L and 6.2L V8 that uses DFM (Dynamic Fuel Management). As the plants get upgraded, the engines are switching from AFM to DFM.

GM’s period of exclusivity will be running out soon, so other automakers will likely start using it too.

Lets just hope, that the will (or tantrums) from uhhhh, some other dark forces don't get THEIR way

My wife's 2015 Benz has start/stop and has had no issues. My son's 2019 Cruze has same with no issues. Both have about 90k miles. I picked up a 2024 XT5 last year and first thing I did was order a $20 cable that plugs inline with the hood latch switch that permanently disables my stop/start. Problem solved.

Depending on your driving habits, I believe stop/start is great way to shorten battery life.
I inherited a 3-yr old honda cr-v from an elderly aunt, which was the proverbial grocery-getter. The battery held a charge for about 10 days when i got it. Honda specifies an EFB (enhanced flooded battery), which is more tolerant of the stop/start cycling. You can replace EFB with AGM (which is what I did) and get normal life by always disabling the stop/start. For same size, the AGM was $100 cheaper than EFB. Doubt start/stop is saving me that $100 in fuel cost over 3 years.

If my Camaro had start stop function I would not have bought it!

Our Subaru has stop start in it and when My wife and/or I get in to drive it we shut that off. I Hate that feature glad I don't have to deal with it in the Camaro.

When the EPA guy refers to the technology as a way to claim "a climate participation trophy" I think it's days are numbered. However, it was originally implemented to achieve numbers under the EPAs instrumented testing so he's also saying our testing procedure is bunk.

I have it on my ZL1 M6. It's called Hill Assist
