ICE aren't growing much in size and are getting more and more efficient. Why not make them air cooled? Porches used to be aircooled, and those were performance cars with the engine in the back. I would imagine having an engine in the front might be easier to cool, no?

I don't think so. I am not sure, if air cooled engines are even capable of meeting today's emission (noise and pollution) requirements.

Furthermore cars with internal combustion engines are currently in the process of being phased-out in favour of battery-electric cars and many manufacturers allocate less and less resources to engine development. The goal seems to be to make existing engines compatible with upcoming emission standards (e. g. Euro 7), phase-out unprofitable engines before new emission standards, and allocate the rest of development resources to new battery-electric platforms and models.

Air cooled engine makes less power, less torque, dumps heat into the cabin, less reliable. No way it's making a comeback regardless of what full ev will be in the future.

Is it less reliable though?

The minimal cost savings (and space savings) wouldn't negate the massive horsepower drop and livability penalty that an air cooled engine would result in. Hell, even in the motorcycle world which still had some that were air cooled are moving even more into liquid cooling.

They're still a thing on motorcycles, atvs, side by sides, lawn mowers, etc. Everywhere but cars.
