What is the use of Civic's S gear?

[AnnieLee]

S gear is the sports mode of the car ("S" stands for "Sport"). In S gear sports mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer time, allowing the car to move at low gear and high RPM for an extended period, thereby achieving greater torque output and acceleration. The following are related introductions about S gear: 1. Since S gear only delays upshifting without changing other working aspects, it will inevitably increase the load on the transmission in a short time, accompanied by a rise in temperature, and the resulting wear will also intensify. Therefore, try not to use S gear for a long time. 2. In terms of fuel consumption, because the fuel injection volume increases at high RPM, the fuel consumption in S gear mode is also much higher than in normal mode. 3. Cars that drive in congested urban areas for a long time tend to have more carbon deposits in the engine. Therefore, using S gear appropriately at regular intervals helps remove carbon deposits in the engine, improve fuel economy, and extend the engine's lifespan.
