EPA possibly goes after the Start/Stop System!

OK, this will turn heads:

I get an argument that, considering the number of vehicles, there are savings in CO2 emissions. An estimate is 10 billion tones annually.
But here is where the problem is: until China and India seriously tackle pollution, all that is irrelevant. On other hand, it add cost to new vehicles, we see issues with oil rings and engine mounts. It adds cost to maintenance!
It is a populism, not sure what will be an end result and whether manufacturers would act on it considering possiblilty for another administration just to bring it back.

IMO start/stop fits right in with more junk auto technology eg self retracting seat belts, starter interlock, etc.

Thank god

Mine gets turned off every time I start the car. Developed the habit right away after getting the car.

I am wondering if we ditch all this stuff, heavier starters, batteries, etc. and bring back weight from let's say 2000, what would be the average mpg? I don't think safety standards are increasing weight as much, considering materials used in crumpling zones etc.

Take into consideration there is a cottage industry of aftermarket solutions.
I had on VW Atlas reverse cable. Basically, you connect to the button. and then harness that was initially connected to button. Basically, it tells the ECU that you pressed the button to turn it off. If you press the button, it turns it on.
I mean, on long lights or train crossings, I would press it if we are talking several minutes.

To require ESS and allow remote start is one of the dumbest automotive contradictions ever.

100%!

It's never truly been about emissions, money is what they are essentially after. Pay penalties and pollute away.

Good! All that garbage to save a shot glass of fuel a day. The last one I had as a rental didn’t work (thank goodness) cause the battery was low. Great invention!

2025 Rams have what I would call poor hotel load management. And, I feel, AGM batteries don't handle cold weather, and sitting on a car lot for extended time very well. Quite a problem with no starts. You can boost the AGM main battery, but it won't start. You have to boost the stop start AGM battery, get it to go. Mechanics told me the batteries are setup in series. Weakest link dies first, which is the 200 CCA stop start battery.
The good thing is the 2 batteries are easy to service.

+1 more garbage that adds to the cost of a car.

Good times!
Hope the next target is CAFE.

10 billion is still 10 billion. It's not like starters are failing any sooner than starters of the early 2000's. I would argue that hybrid powertrains are harder on engines with regards to oil burning and people aren't complaining about that.

Manufacturers who haven't already will just add a button to turn it off.

I remember when I did tree work and the epa went after 2 cycles, 25 yrs ago. Meanwhile a diesel bus in a big city could fog an entire block. Some think tank the epa is.

The answer is all around us. It's today's compact and sub-compact.

Here are the MPG numbers between an E46 330 and the current G42 230i.

City 18 mpg vs 26 mpg
Hwy 25 mpg vs 35 mpg
Combined 20 mpg vs 29 mpg.

I actually really struggle driving hybrids because the constant switching on and off of the engine really bothers me. Even driving at 70mph+ down the motorway, every time you lift off the throttle the engine shuts straight down, then as soon as you apply power again it fires back up again. I can't help but feel like it's not doing the engine any good.

That said, plenty of very high mileage hybrids about now and they've been around long enough to show it's really a non-issue. It just goes against everything I was taught.

I have never understood the hate for start/stop.

me neither. alot of the systems are smartt enough NOT to shut the engine down until it's warm so the cold start wear is that of a normal vehicle anyways
