[QUOTE="ToyTundra, post: 2027893, member: 558970"] the question isn't speed and getting there faster it's the increased drag caused by going faster. Drag is cV^2 where c is a constant relating to the frontal area and overall aerodynamics. twice the speed = 4 times the drag. I've read 55 is the most efficient, but that depends on the vehicle: My truck total trip 240mi each way. @80mph (empty bed)18.3mpg @70mph (bed loaded) 19.6 mpg it's not 100% accurate because of the load though [/QUOTE]
