Auto makers can continue to use start/stop it simply won't be mandatory. I loath this feature myself and don't know a single person that likes it.

 

Its not mandatory now

 

Essentially it is so auto makers can receive emissions credits and meet CAFE regulations.

 

Thats different than saying its mandated. CAFE regulations in the long term aren't going anywhere and manufacturers know this.

 

CAFE standards will become irrelevant and replaced with something else when all cars are battery electric.

 

In the many many decades from now when that happens sure

 

I had no idea the M3 had this. I figured BMW would have dropped it for M models.

Off topic here geko, but I saw that dark blue M3 with those awesome wheels driving home from work. He was pulling out of the same shopping center as last time. It looked so freaking sweet!!

 

IDC how seamless it is, I don't want it.

Other "tricks" are ok by me, like cylinder deactivation as long as reliability isn't affected. I know that helped me get 25MPG in the Yukon that day. You can't tell when it's working and they've had it for like 15+ years to try to get it right. It seems like it works and is completely transparent.

 

They get a credit of 1.5g/mile, or 2.5g/mile if this is paired with an electric coolant pump (or equivalent functionality). Most recent new car average emissions I've seen is 347g/mile from 2022. So it matters mathematically, but only a tiny bit. After next year the standard drops to 161g/mile fleet-wide, so it will become more impactful (to about 0.9%). But the total amount of off-cycle credits that can be earned (there are close to a dozen ways to get them) also drops from 15 to 10g/mile. So already less likely to be "necessary" to achieve the maximum reduction.

 

I have yet to feel one that is truely invisible, especially if you have a tuned engine/trans that doesn't artificially delay inputs.

Same on reliability, I stupidly tried to leave it enabled on my 4.0 and it just kills plugs.

 

I agree that this feature is annoying, can put extra stress on the battery and starter (and, sometimes, motor-mounts if it is jerky), and I'm with those who generally dislike it. But, IMO, I also think the best compromise is to, instead of doing away with the system altogether, simply change the Deactivate button to a permanent one, that you push it and it STAYS deactivated. The current button only shuts the system off until you formally shut the ignition off...and then you have to push it again every time you get in the car and start the engine again....which, of course, eventually wears out the button itself. Automakers allow you to permanently shut off a lot other of things.....traction-control, VSC, lane-keep feature, automatic trunk-release, etc... and some of the infotainment functions, but oddly, not the start/stop system. But some people (not a whole lot) do want the engine start/stop for fuel-economy, and that's why, IMO, they should modify the disable-button instead of the system itself.

 

Despite the grandiose plans of some auto makers (which are already being scaled back), I don't think the auto industry will ever convert 100% to battery electric..... at least in any of our lifetimes. Too many potential customers simply don't have access to either home-charging outlets or other charging outlets close by. They have no choice but to have either ICE or hybrid vehicles. Also long trips in sparsely-settled areas can be a problem with full-electric vehicles...... particularly in harsh weather or other conditions that rapidly drain the battery.

 

EV adoption is happening rapidly you don't see it so much because the United States is badly lagging.

 

Look at what has happened to Tesla in just the last six months or so.

 

Extremely myopic thinking.
