The most economic driving style is gradual acceleration and > gentle braking. Generally well-known, but a "fact"? I'm not so sure. Holding a constant cruise speed by flapping the accelerator up and down is obviously stupid, and the economics are (to me) unimportant. And I don't see that braking gently saves any more fuel than leaving four big black marks on the street (although the latter is a bit rough on the tires, which aren't much cheaper than fuel these days :-) But I have seen many references that the old "drive as if there was an egg between your foot and the gas pedal" method is an inefficient way to accelerate. These references suggest that the proper thing to do is to smoothly depress the accelerator pedal to the floor (not jab it to the floor). Shifting should be done at the lowest practical RPMs. I don't know how reliable any of these claims are. I do know that I use full-throttle acceleration, and I usually get about 1 mile per gallon better fuel mileage than my wife does from the same car. And I have a lot more fun when driving :-) -- Doug Pardee -- Edge Computer Corp., Scottsdale, AZ -- ...!ihnp4!mot!edge!doug
