I was trying to research the topic of how higher rates of speed use a greater amount of gas then that at lower rates of speed. I'm mainly looking for help here to find some credible sources to back my opinion up. If you could help me out by providing links to credible websites which can help me prove this point then that would be very helpful. Also, I need the results to be more on a general basis and not just for one make of car.
Thank you

One simple way to consider the effect of speed on gas mileage is to consier the energy lost due to friction.
From Wikipedia:
Note that the power needed to push an object through a fluid increases as the cube of the velocity. A car cruising on a highway at 50 mph (80 km/h) may require only 10 horsepower (7.5 kW) to overcome air drag, but that same car at 100 mph (160 km/h) requires 80 hp (60 kW). With a doubling of speed the drag (force) quadruples per the formula. Exerting four times the force over a fixed distance produces four times as much work.

i have always heard the faster you go the more gas you burn. i can't really prove it unless i'm running over 110 mph, then the fuel gague will drop faster. sorry, but i think if you could do a steady 55 or 60 on an interstate you would probably get the best mileage??
