That being said, forget about getting 100MPG out of any gasoline vehicle that's heavier than 500LBS.

I believe the optimal engine is a 300CC engine, single or ptwin engine, geared in such a way that it would reach 2k RPM at 60MPH in final gear.

Take reference car 2550LBS 'Fiesta ST' with 1 liter triple cylinder turbo enigne, and ~45MPG real life avg MPG.
Or, the Mitsubishi mirage with their 1 liter NA engine 2000LBS, 50 real life avg MPG car.


Top speed 80+ mph

250.6 mpg at the Green Grand Prix in 2015.
