I don't want to derail the thread... and though I understand your sentiment, but in the car world, there is something call a "torque ratio" and a "horsepower ratio".

The torque:weight (tq/lb), often called the torque ratio, defines how many pounds of weight the vehicle has per ft lb of torque. The smaller the ratio, the quicker the vehicle can accelerate and the more fuel efficient it is. The horsepower:weight (hp/lb), often called the horsepower ratio, defines how many pounds of weight the vehicle has per horsepower. The smaller the ratio, the faster the vehicles top speed will be and the more fuel efficient it is.

Example... My son and I both have a car that weighs 4,000 lbs. His car makes 400 ft lb of tq and 385 hp. His car has a torque ratio of 1:10 and a horsepower ratio of 1:10.4.

My car makes 500 ft lb of tq and 485 hp. My car has a torque ratio of 1:8 and a horsepower ratio of 1:8.2. There for, my car is both quicker and faster than my son's. Make sense?

Figured I'd share.
