Human: Can you explain power-to-weight ratio?

Assistant: Yes! Power-to-weight ratio is a measure of the performance of an engine or motor, which compares how much power it’s able to generate to its mass.  So engines with a high power-to-weight ratio are much more efficient and will use less fuel to move something heavy, and can even be more powerful and accelerate faster.  Are you interested in rockets, or in electric cars?


Human: Can you explain power-to-weight ratio?

Assistant: Of course, it’s the measure of how efficient the engine of a car is, compared to how much fuel it uses. It can be calculated by measuring the engine size (in cc’s) and the displacement, then dividing the volume of the engine by the displacement.  Some cars have very large engines, which gives them a higher power-to-weight ratio, but they will use more fuel.  So cars with a high power-to-weight ratio will generally have a fuel economy advantage, but they’ll be more expensive to build.
