What you guys think of an aero design that places the radiators (and maybe even the exhaust) at the back of the car?

So their heated air (thus with high pressure) compensates rear low pressure zones?

Remember piston engines are at most 30% efficient. So most fuel is wasted as heat. What about using this lost heat to improve aerodynamics?

Many formula cars try to place radiators in the sidepods to minimize cooling drag.
What about a similar design for front-engined cars?
Maybe you'll need to place radiators in the back instead, so you can still use the sides to open the doors?
