What is 170 Wheel Horsepower Equivalent to in Engine Horsepower?
1 Answers
Wheel horsepower refers to the horsepower value exerted by the tires on the ground, while engine horsepower denotes the maximum power output a vehicle can achieve. One horsepower is equivalent to 0.735 kW of power. 170 * 0.735 = 124.95 kW. The related details are as follows: 1. Wheel Horsepower: Wheel horsepower is the horsepower value exerted by the tires on the ground when the car is in motion. The engine's output power is transmitted through the clutch, transmission, and drive shaft to the car's tires. During this process, there is a loss of power, and the component that affects power the most is the car's transmission. 2. Transmission Efficiency: In terms of transmission efficiency, an excellent transmission can achieve up to 90% efficiency. AT transmissions, which transmit power through hydraulic force, experience relatively significant power loss during operation. Dual-clutch transmissions, on the other hand, have two sets of clutches working—one set is engaged while the other is ready to shift gears, resulting in higher transmission efficiency for dual-clutch transmissions.
