What does it mean by the @rpm? What car would accelerate faster one with a higher or lower rpm.
For ex the Camaro has
Horsepower: 323 @ 6800
Wat would be faster?
Car vs. Car - You can't really tell much from those numbers unless both cars were the same weight, same setup, ie. tranny, gears, suspension, etc. Also those numbers are rated at the crankshaft. The real number is when it's measured at the rear wheels, that's where all the components are factored in.
HP vs. Torque - They work hand in hand, but HP gets the car up to speed and maintain. Torque is the key. Think of a cheap ceiling fan. It can turn pretty fast, but you can stop it fairly easily with your hand and prevent it from turning - Low Torque. As the motor has more torque you can't stop it or slow it much. In your car, more torque means it gets HP to the ground and launches your car or gives you a great passing burst. When you're doing 70 and punch it to pass, torque gives you the acceleration.
