> But why would you put an 800cc engine in a full-sized sedan? You have plenty of room to fit a decent turbocharged two-liter four-cylinder.
You will have to, and you say "The size of the car is in no way constrained by the engine size," which is a complete nonsense. On the lower end, it's constrained by sellability of a car, and on the upper end it's physically constrained by the size of car frame.

Yes, and that's a very big advantage. Even very tiny EVs can have batteries with hundreds of kilowatts of power output.
> On the lower end, it's constrained by sellability of a car
Yes, as already said, I completely agree.
> and on the upper end it's physically constrained by the size of car frame
In theory yes, but in practice you don't really feel this limitation, that's my point. As I said, you can fit a K24 engine into a Honda Fit (B-segment supermini car) without modifying the frame or bodywork. A turbocharged K24 can put out 300 kilowatts without breaking a sweat.
