What is the S gear in an automatic transmission car?
1 Answers
Automatic transmission car's S gear is the sports mode of the vehicle. In S gear sports mode, the transmission can freely shift gears, increasing the engine's output power to achieve greater acceleration. Situations where S gear should not be used: 1. Using S gear when the car is just starting can have a counterproductive effect on speed increase; 2. It should not be used during high-speed cruising. Automatic transmission means that the driver does not need to manually shift gears; the vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. The principle of automatic transmission is: using planetary gear mechanisms for shifting, which can automatically change gears according to the degree of throttle pedal and changes in vehicle speed.
