What does the S gear in an automatic car stand for?

[AmyDella]

The S gear in an automatic transmission stands for Sport mode. When shifted into this gear, the transmission can freely switch between gears. Below are the specific details about the S gear in an automatic transmission: 1. The S gear merely delays the shift timing, maintaining high engine RPM for a period to enhance the car's power without altering other operational aspects. 2. The S gear increases the transmission load in the short term, accompanied by a rise in temperature, which also leads to accelerated wear. Therefore, it is advisable to avoid prolonged use of the S gear. 3. Cars frequently driven in congested urban areas tend to accumulate more carbon deposits in the engine. Thus, periodically using the S gear appropriately helps remove engine carbon deposits, improve fuel economy, and extend engine lifespan.
