Here's the thing. A 68 Mustang had no almost emissions controls. A 78 Thunderbird was almost the exact same stuff, except it was choked to shit. A modern computer-controlled Camry is not only way better performing, it also orders of magnitude cleaner.

IMO the ICE has achieved its final form, so now the future has to be something else (electric).

RE: "ice final form"

It's an intersting time to live, we are indeed seeing the peak of ICE, though I think there are lots of room for improvement in EGR, compression, more efficient catalytic process.

"smaller market" ICE manufacturers IE isuzu, mazda, hino etc. are sort of working towards this, as opposed to jumping on EV train.

Theoretically, it's completely reasonable for a high compression inlne 3 cylinder with aero wheels/tires to get 60-70 MPG. (With proper EGR, turbo application, CVT)

I think the major carmakers aren't interested in super-economy ICE cars.

They're attracted to XXXXL EVs because they can make the XXXXL cars they want to make and still claim they're "green"

50mpg from a 5.7L V8, using most of the drivetrain from a truck(!)

My daily driver gets roughly half that, but it has a carbureted 6.6L and an automatic transmission, with some mild performance tuning done. I am satisfied enough with that.

Really none of that is improving the ICE.
