What’s better, horsepower or torque?
Both, which combine to make Average power.
We shall establish 3 things after the break:
-Torque measures instantaneous acceleration
-Torque applied over several thousand RPMs measures total acceleration
-Gearing scales torque at the wheels
Now picture this:
Car A makes 600 lb-ft from 1000-4000 RPM
Car B makes 600 lb-ft from 1000-7000 RPM
Identical weight, gearing, wheels.
A and B are neck and neck UNTIL 3000 RPM where A shifts into 2nd gear, dropping its torque at the wheels. Meanwhile, still in 1st gear, B rockets ahead, and eventually wins the race.
What’s the difference? Car B applied more torque at the wheels for a longer period of time, because 1st gear lasted longer). Car B had more average power because its rev range lasted twice as long.
