Given todays economic climate, possible scaricity of fuel, and of course just the raw challenge of building a car with high mpg,
we should have a thread on cars of this nature, in production,prototypes,homebuilts, concepts and pictures. ( I wish i had the time and energy to build a car with a sub 1 litre engine, and maybe one day i will) but lets keep it to combustion power, for now |

I don't understand why everyone thinks low RPM=better mileage. You need more throttle to keep speed then. More-throttle=less vacuum=less efficiency. Think somewhere I read you want to be in cruise speed at 60% range of your max HP RPM. You would need to build a super torqy, low RPM engine to gain anything. I remember going from 4:11 to 4:88 gears on my Toyota PU and the mileage went up about 5 MPG.
