7. 300cc's?

My lawnmower has a bigger motor. My motorcycle has more than twice the displacement. Why a one-cylinder? It'll vibrate.

Even so, I find 200+mpg to be implausible. It takes a certain amount of energy to "lift" a load to a given speed, and a car (no matter how aerodynamic) has to do it multiple times, quickly. A loaded two-seater probably can't weigh much less than 3/4 ton.
