Would you rather have 500 HP and 600 pounds of torque, or 550 HP and 600 pounds of torque? I think you'd want the revs that make that 550. If you do have a combo of 500 HP and 600 pounds of torque there is probably something wrong with the combo and not as effiecent as it should be. I guess I agree its torque at the rear that moves the car, but that torque has to come at RPM's, which is power...which accelerate the car, eh?
