why do some smaller engines have lower gas mileage than some larger engines?
In: 208
There was an old episode of Top Gear where they ran a Prius around the track flat out. They followed behind with a BMW M3. The M3 was driving at a leisurely pace to keep up with the Prius and had better gas mileage as a result.
Big engine slow > small engine fast.

As well as how hard the engine is working, there’s often simply the fact that a smaller engine had been optimised to give high end power would a larger engine may well be optimised for efficiency.
For example a 1l bike engine might produce over 150bhp, but even running lower down the rev range it will never be as efficient as a typical 2l car engine, it’s made to be powerful and light weight.
