Ok here is the Situation:
You car gives 30 Miles to a Gallon at 70Mph. At 70mph ( last gear ) you are in the middle of your powerband. The distant you have to travel is 33 Miles. You have only 1 gallon of fuel in your car. What do you do? Do you slow down your car burn less fuel? OR do you speed up? All road and air conditions are ideal. |

i still would say lowest RPMs youcan run in 5th gear w/o having any acceleration.
based on Saleeka's thread, i agree that you only should need as much torque as to keep the car going against air resistance, and engine resist. hitting a max torque would most likely help the efficiency of the engine, but the surplus of power would bring this overall down a few notches... just a hypothesis --------------------  |
