When can the S gear in an automatic transmission be used?

[VonNora]

Automatic transmission S gear can be used when overtaking, going up or down slopes, and in traffic jams. When overtaking: The S gear can instantly provide high torque, allowing the car to accelerate quickly in a short time. When going up or down slopes: Whether ascending or descending, on steep and long slopes, using the S gear to downshift can utilize engine braking, reducing reliance solely on the brakes and enhancing driving safety. In traffic jams: The S gear can lock the gear in a low position, reducing wear and tear on the transmission caused by frequent gear shifts. The S gear is a sports mode. When switched to S gear, the car's power increases directly, turning into an aggressive mode, which is different from the usual gear. Therefore, prolonged use of the S gear can accelerate the wear of high-speed rotating components inside the engine due to this more aggressive driving mode.
