I don't know why you are being downvoted. You are correct, and some ICEs (large, maritime) are hitting 50% even. For a thermal engine, that's incredibly good (it's not about the gap to 100%, but the gap to Carnot efficiency).

There's a strong contingent here on HN that believes tha continued used of ICEs equates to the imminent death of the human race.

It's also a likely wealthy contingent that imports all of its food, flies everywhere, etc.

On what grounds do you draw that connection?

Previous threads, comments & votes.

... except the cost of the ICE drivetrain, certainly to hit 40% (that takes turbos and other complexities to the basic ICE, correct?) is about to lose to the cost of the EV drivetrain. It's basically at price parity based on what I see out of Tesla and what Lucid/Rivian/VW/GM are targeting. In three years? Less.

And a decade from now? EVs will probably be half the cost of an ICE.

Because of battery energy density, EVs still only work within a certain size&weight range.

ICE work in a much broader range of applications and at wider temperature extremes. They aren't going away.
