Who cares? My point, in the original post is that HP is derived from torque at a specific RPM. The engine rotates. It applies force by rotating. Therefore, everything from the engine is dervived from its torque at a specific RPM. If I know the torque and the RPM, I can derive its energy output; whether in HP or KW; but I can derive its power. If I know its maximum power, I still need to know its RPM to dervive its torque, or its potential. Either way, power, gives no indication as to the performance of the car unless you know a whole lot of other things.
I have a 300 HP car with 300 lb-ft of torque at its peaks. It easily smokes my friend's 73 Dodge producing 342 HP (at the wheels) with 320 some-odd lb-ft at the peaks. Why? Because my car is lighter, geared better, and is AWD. HP alone will not give an indication as to the car's performance.
