What is the main function of the S gear in a car?
1 Answers
S gear is the sport mode of a car (S stands for sport). In S gear sport mode, the transmission can shift freely, but the shifting timing is delayed, allowing the engine to maintain high RPM for a longer period. This enables the car to run at low gear and high RPM for an extended duration, resulting in greater torque output and acceleration. While driving, simply push the gear lever into the S gear position. It is typically used for climbing hills and quick overtaking. More details are as follows: 1. S gear and vehicle performance: As a sport mode, it delivers outstanding performance in terms of vehicle movement. When climbing a hill, shifting into S gear provides greater power, making driving easier. Similarly, during overtaking, it quickly boosts power output to achieve the overtaking goal. Additionally, S gear helps increase engine load in a short time, which aids in clearing carbon deposits inside the engine. 2. The role of + and - in S gear: The + and - in S gear refer to the manual mode of an automatic transmission, a feature found in more luxurious vehicles. Its main function is to switch the gear into manual mode. When shifting from D gear to S gear, it becomes manual first gear, + represents manual second gear, and the highest is third gear. Essentially, this follows the principle of a manual transmission but is more intelligent. Although S gear offers strong power, it requires higher torque output, leading to relatively higher fuel consumption.
