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. And there is no way EVs need less space for battery + motors in total. Have you seen the size of a Model X battery pack? Only difference is they typically use space below the floor of the car, rather than in front. They are typically a bit wider than ICE cars to compensate and give sufficient interior space.

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. > Only difference is they typically use space below the floor of the car, rather than in front. Yes, and that's a very big advantage. Even very tiny EVs can have batteries with hundreds of kilowatts of power output.

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.

    It is a limitation, i4 is an upper limit what you can put in it, and a 300kw i4 will vibrate itself to pieces in prolonged use. Using bigger engines, for bigger cars really makes sense.

location and structure matter in system design. even if the battery takes up more total space than an ICE no one is going to notice the car being 1 inch taller overall for consumer vehicles.
