How to Determine a Car's Power?

[BennettMarie]

Car power can be judged as follows: 1. Maximum Speed: The highest achievable driving speed of a car under windless conditions on a level, good asphalt or concrete road surface. 2. Acceleration Ability: The capability of a car to rapidly increase its speed while driving, usually expressed in terms of acceleration time and acceleration distance. Acceleration ability includes two aspects: standing start acceleration and overtaking acceleration. 3. Climbing Ability: The maximum gradient a car can climb when driving in first gear on a good road surface. It is required to be able to climb slopes of no less than 60% or 30 degrees. For trucks, a climbing ability of around 30% is required. Since passenger cars have higher speeds and often operate on well-maintained roads, their climbing ability is not emphasized, generally being around 20%.
