If the motors are light enough, though, that might be acceptable... especially if they can make an even smaller version for that application. (You probably don't need 750 kW on each wheel - even for a supercar that'd be excessive.)

fwiw four of those electric motors is approximately 4,000 hp. You won't get better 0-60 times with that though, at that point, you're limited by the tires' physical limitations. So at best you could get down to a ~2.2 second 0-60 mph time with regular tires, and then after that, you'd need race sticky tires in order to go faster.

Unless you used the motors to power fans instead, then you could use that for downforce and propulsion, and get well belown 2 seconds, theoretically.

F1 cars with fans to run them upsidedown but with remote drivers for their safety maybe?

Yeah, the potential here reminded me of the McMurtry Spéirling, which uses fans for active downforce, and gets 0-60 in 1.4 seconds. Top Gear Video link: https://www.youtube.com/watch?v=HPZxcfglU2Q
