RE: Hp v Torque
HP is is basically how fast torque gets its work done. So... if you wanna pull stumps then be more concerned with torque, if you wanna accelerate fast in a car then be more concerned with hp.

RE: Hp v Torque
lol torque don't win races, I'll ask ya this question...
two identical cars, everything the same... (just pretend)...
one car has 500 hp and 350 lbs of torque
the other has 350 hp and 500 lbs of torque
Torque gets things moving, hp is what gets em moving fast. Afterall, hp IS just a measurement of torque

I personally like the description the autoshop teacher at the high school I work at gave me. He said Torque is a measure of work that can be done and HP is a made up number. Actually if you know the Torque your car makes, there is a formula to get the hp at a give rpm.

RE: Hp v Torque
Here's some info quoted from a webiste:
"First of all, from a driver's perspective, torque, to use the vernacular, RULES :-). Any given car, in any given gear, will accelerate at a rate that *exactly* matches its torque curve (allowing for increased air and rolling resistance as speeds climb). Another way of saying this is that a car will accelerate hardest at its torque peak in any given gear, and will not accelerate as hard below that peak, or above it. Torque is the only thing that a driver feels, and horsepower is just sort of an esoteric measurement in that context. 300 foot pounds of torque will accelerate you just as hard at 2000 rpm as it would if you were making that torque at 4000 rpm in the same gear, yet, per the formula, the horsepower would be *double* at 4000 rpm. Therefore, horsepower isn't particularly meaningful from a driver's perspective, and the two numbers only get friendly at 5252 rpm, where horsepower and torque always come out the same."
