What is the main function of the P gear in a car?

[DiKeira]

P gear is for parking. It uses a mechanical device to lock the rotating part of the car, preventing the car from moving. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after parking, you should engage the handbrake and push the lever into the "P" position. Relevant information about automatic transmission is as follows: 1. Introduction: Automatic transmission, as the name suggests, does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Generally, there are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L. 2. Automatic principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume more than 10% more fuel than manual transmissions. Whether it is a manual or automatic transmission, the more gears there are, the more fuel-efficient it is.
