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 |

It might also overheat, due to lack of airflow from keeping engine revs low. You would need: Modern FI Tall transmission gearing Electric cooling fans A more slippery body kit Goal would be to have the engine turning under 2000 RPM at freeway speeds, and not have to drive it faster then 65mph. On a water cooled engine it is easier. You shift from 1-3-5 skipping 2 and 4, and moving to higher gears as soon as you can to keep engine revs low. Nothing is done fast. Cruise some of the hypermiling websites for more ideas (and lots of home built aero bodies. Zach |
