Which is better hp or torque?
Horsepower is how rapidly the vehicle can perform that work. … Of course, horsepower is tied to torque mathematically. Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Does horsepower make a car faster?
For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower. Torque, on the other hand, is the expression of a rotational or twisting force. In vehicles, the engines rotate around an axis, thus creating torque.
