DrInnovation said:The super-lightweight i3 could get a lot of MPG out of a small motorbike engine, but even on a BMW motorcycle, which is literally a ton lighter lighter, the best was 62MPG (on a F650GS I believe).
Most motorcycles, with the rider, are grossly inefficient aerodynamically, compared to a clean small car. If you put that 650cc engine in a streamlined body of the same weight as the original motorcycle, the fuel economy would skyrocket.
Weight is only one factor.
