What is the function of the S gear in a car?
2 Answers
Car S gear is the sports mode of the car. The following are specific introductions about the S gear of the car: 1. In S gear sports mode, the transmission can shift freely: the shift timing is delayed, keeping the engine at high speeds for a longer time, allowing the car to travel at low gears and high speeds for an extended period, achieving greater torque output and acceleration. While the car is moving, simply push the gear lever into the "S" gear, which is typically used for climbing hills and quick overtaking. 2. The main principle of S gear is to make the throttle response faster: the engine speed is also maintained in a higher range, thereby providing high power output. However, when using the S gear, it is necessary to control the speed reasonably to ensure driving safety. 3. The benefits of car S gear: The advantage of S gear is that it can increase the engine load in a short time, which is helpful to some extent in removing carbon deposits from the engine.
I used to drive in S mode frequently, thinking it mainly comes in handy when you need quicker acceleration. For example, when overtaking on the highway, shifting to S mode makes the car respond faster—the RPM shoots up immediately, and the car surges forward to pass. But during traffic jams or leisurely driving, it's completely unnecessary. Using it causes fuel consumption to spike, and the engine roars loudly, as if protesting. I recommend using it only on winding mountain roads or open road conditions. Overuse can harm the engine, as the shift points become more aggressive, leading to faster wear on components over time. Honestly, it's better to keep the car balanced—don’t always prioritize thrill-seeking.
