Torque doesn't accelerate the car alone its Torque X Rpm that does which is HP. Which is the definition of horsepower is to move Weight over a Distance in a certain amount of Time, EG... accelerate a car (weight) over a 1/4 mile (distance) in a E.T. (certain amount of time). If torque only mattered then they wouldn't of needed to come up with horsepower ratings, rpm is an equal force to torque, without either your car is going nowhere.
Again its Torque X RPM
