How much horsepower is in one cc?

Answer 1

Power ourtput and engine displacement are not directly related. While it is true that larger displacements usually allow for greater power output, the efficiency of the design, in terms of horsepower per cc, can vary widely. For example, a well designed motorcycle engine gets at least 100 hp out of less than a liter of displacement, while most subcompact car engines make about 90 hp with 2 liter engines. But it should be remembered that the car is at least 5 times heavier than the motorcycle, so it's engine is built to be a lot more durable.
