When to Use the S Gear in an Automatic Transmission?

[MaciRose]

Automatic transmissions use the S gear when overtaking or climbing hills. The S gear in an automatic transmission is a sport mode that emphasizes power output. When shifting to the S gear, the transmission can freely change gears, but the shift timing is delayed, keeping the engine at high RPMs for a longer period. This allows the car to operate at a lower gear with higher RPMs for an extended time, resulting in greater torque output and acceleration. For cars frequently driven in congested urban areas, where carbon buildup in the engine is more common, using the S gear periodically can help remove carbon deposits, improve fuel economy, and extend the engine's lifespan.
