It's all about horsepower. Torque is a value used to compute horsepower. Horsepower is the amount of work in time. The formula for torque does not involve time. I personally live in time. Because of the nature of gasoline and diesel engines, they make torque at different RPM's, which effects where the horsepower is made. People think cause an engine is rolling over at 1600 rpm making max horsepower cause the torque curve starts at idle and stops at 2300 rpm it is a much stronger engine then another making the power at higher rpm where it's higher torque curve is located. Ain't so, just different rpm band, and different characteristics, and whatever people want to believe.
