NOOOOOOOOOO, LIES!

incorrect you get better milages around 65-80mph keep in mind putting your foot hard down will severly decrease your milage as the amount of gas is increased. slowly accelrating and then setting cruise at 80mph will get far more effeciency out of your gas. also the slower you drive being 55 and less the worst becuase your probly not going a constant speed. point tho if you dont want to pay for gas dont fucken drive. or get a diesel and run on fry greese

If I remember correctly, the most efficient speed for gas mileage varies according to engine size, larger engines having top efficiency at higher speeds and smaller ones at lower speeds.

Looks like the reality is pretty much the opposite of what I just said: smaller, lighter cars are most efficient at high speeds and larger, heavier ones are most efficient at low speeds. See How Stuff Works.

^^very true. so neither of you guys are wrong just slightly misinformed. since he drives a truck it is a larger 4cyl or small v6 which means that he will get better gas mileage at 75 than a honda style motor. same is true for me. my subie has a larger 4cyl, 2.5l, so i get better gas mileage at 75 than the hondas.

That is what I thought, but apparently aerodynamics and weight have something to do with it as well. I am not sure which factor has a larger influence, engine size or the "bulkiness" of the vehicle.

that site at howstuffworks doesnt say that larger engines are LESS fuel efficient at higher speeds or anything of that sort. its just saying that the power required to change go from one speed to another and the associated usage with changing speed. a tightly wound engine (a honda b series like the integra motors) will turn over MANY more times than my 2.5l subaru motor will. why? because the honda motor is made for HIGH rpms. this uses more gas and therefore lowers fuel economy. this is why a v8 actually gets BETTER mileage at 85mph than a 4cyl will. just think about it in terms of a runner. a short runner taking long strides will work harder to be as fast as a tall runner taking average strides.

and yes aerodynamics, weight, tires, body shape, underbody aero coverings and drag coefficient all have a factor in this equation.
