Which is More Important: Maximum Horsepower or Maximum Torque?

[AdelineLee]

Both maximum horsepower and maximum torque are important. Maximum Horsepower: Refers to the maximum power output a vehicle can achieve, measured in PS (Pferdestärke), which is equivalent to the maximum power data. Power is defined as the work done by an object per unit of time. The higher the power, the higher the rotational speed, and the higher the top speed of the vehicle. Maximum power is commonly used to describe a car's dynamic performance. The level of maximum horsepower affects a car's top speed, while torque influences the force during acceleration, including initial acceleration. Theoretically, the greater the torque, the faster the initial acceleration, resulting in a shorter time from 0 to top speed. If a car has high horsepower but low torque, acceleration will be very slow, making the driver feel the car lacks power. Maximum Torque: This is the moment output by the engine from the crankshaft end, measured in N·m/rpm (Newton meters per revolution per minute). Maximum torque typically occurs in the engine's mid to low RPM range. As the RPM increases, torque tends to decrease.
