Engine bays have a lot of design go into where to keep heat and where to get rid of it. You can look up thermal coatings and ceramics etc.

Sure and it all routes to dump the heat to...where again? A vacuum? Or to a radiator with a fan with some kind of cooler fluid/gas from the environment constantly flowing through it?

Seems like quite a massive difference to ignore.

Let's just hope the person you are responding to isn't Elon Musk!

I wouldn't say that roadster isn't doing much driving but dang is it drifting!
