What Does a Car's Power Performance Mainly Refer To?
1 Answers
A car's dynamic indicators are primarily reflected in maximum speed, acceleration capability, and maximum climbing gradient, which are the most fundamental and important manifestations of a car's performance. In China, these indicators are obtained by automobile manufacturers through prototype vehicle testing according to the national prescribed test standards. Maximum acceleration refers to the time required for a car to start from a stationary state, shift gears continuously to the highest gear with maximum acceleration intensity, and accelerate to a certain distance or speed. It is the most important parameter that truly reflects a car's dynamic performance. There are two expressions: the number of seconds required for the speed to accelerate to 1000 meters (or 400 meters, or 1/4 mile); the number of seconds required for the speed to accelerate from 0 to 100 km/h (80 km/h, 100 km/h). The shorter the time, the better. It is particularly important to note that the testing of acceleration performance is closely related to the driver's shifting skills and the environment. Different driver skill levels, different roads, and even different climate conditions will reflect different acceleration times. The parameters provided by the factory are often the best values that the prototype vehicle can achieve, so as a user, this parameter can only be used as a reference.
