What do Maximum Power and Maximum Torque Mean in Cars?

[AllieFitz]

Here are the explanations for maximum power and maximum torque in cars: 1. Maximum Power: Maximum power refers to the maximum rate of energy change per unit time on a circuit element, which is a physical quantity with magnitude and sign. Here, it specifically refers to the maximum output power. The greater the maximum power, the more devices the power source can support. 2. Maximum Torque: Maximum torque generally occurs in the medium to low engine speed range and tends to decrease as the speed increases. The unit of torque is Newton-meters or kilogram-meters. Torque affects the vehicle's acceleration force, including the initial start. Theoretically, the greater the torque, the faster the vehicle accelerates from a standstill, and the shorter the 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.
