As for input air, why not ducts in the sides of the car? And then you could make it mid-engined, kinda like this: Lotus Elise - Wikipedia, the free encyclopedia

I don't get how this works. Heating causes air to expand, but why would that expansion force be applied to the rear any more than to the front of the radiator? It should resist airflow from the front just as much as it pushes air out the back.
