If you drive in the right gear for the demand, accelerate in short time at optimum rpm of the engine, and many other things. But you in the US use mostly automatic gear shifts I think, shifting manual is more fun, gives you more control and allows you to save fuel.

If you drive real efficient, with an efficient car, you can drive 80 mph (130 km/h) by using less then 47 mpg (5l/100km). Slower driving does less than efficient driving, and that can also be faster in some cases. That?s not average and not with every car but possible.

Certainly, efficient driving in important. Floorbording to fifty five is not going to cut it. By the way, I drive a VW Jetta, it gets 40 mpg around town and fifty mpg on the freeway, if I drive conservatively.
