What Does the Pushing Sensation in a Car Mean?
1 Answers
When a car accelerates suddenly, due to inertia, the sensation of the seat pushing against your back is referred to as the pushing sensation. Cars with better acceleration performance tend to have a stronger pushing sensation. Therefore, the intensity of the pushing sensation can, to some extent, reflect the performance of a particular car. More precisely, a strong pushing sensation in a car actually indicates that the vehicle has excellent instantaneous acceleration performance. Clearly, among the various technical parameters of a car, the one that determines the intensity of the pushing sensation is the maximum torque. In other words, the greater the maximum output torque of a car, the faster its instantaneous acceleration, and consequently, the stronger the pushing sensation. On the Earth's surface, people constantly experience an acceleration g directed toward the center of the Earth, commonly known as gravitational acceleration. Since a car accelerates horizontally, the moment the accelerator is pressed, the power generated by the engine gives the car an instantaneous forward acceleration. The "pushing sensation" also refers to acceleration, but in a horizontal forward direction. Therefore, the "0 to 100 km/h acceleration time" metric released by car manufacturers can be used to calculate how many g's of pushing sensation the car provides.
