[quote=spdrun]As far as 50+ mpg 3000+ lb cars, Prius is close to 3000 lb and gets about 50 mpg, no? Besides, with improved crash avoidance and CAD tech, who says that cars NEED to be over 3000 lb. It’s perfectly possible to build a 4-door that weighs 2500 lb, think Honda Fit.[/quote]
It doesn’t seem we’re really that far off. My car (Hyundai elantra) weighs 2700 lbs and I get 45 mpg freeway driving and 35 on city streets. Is a 20 to 25% increase out of the question?
