>Even better, a two-cylinder FPEG is inherently balanced and would measure roughly 8 inches around and 2 feet long. An engine of that size and type could generate 15 hp, enough to move a compact electric vehicle at highway speed after its main drive battery has been depleted. Is 15 HP really enough to move a car at highway speeds? I had a CBR250 motorcycle that produced 22-24 HP and weighed around 350 pounds, and it was not particularly great on the highway. It's hard for me to imagine a car that's 3+ times heavier with less horsepower being safe on a highway.
