How to Use D/S Gear?

[Jean]

In automatic transmission vehicles, both D gear and S gear are forward gears. Normally, D gear is used for regular driving, while S gear can be used for overtaking and acceleration. S gear provides greater horsepower and stronger power, but it also consumes more fuel. On the other hand, D gear is more economical. Therefore, it is not recommended to use S gear during normal driving, especially at slow speeds. Below are the detailed explanations: 1. D (Driving) is the forward gear. When driving in this gear, the hydraulic control system shifts gears according to the preset program, operating entirely based on the set logic. Simply press the accelerator. 2. S (Sport) is the sport gear. When this gear is engaged, the hydraulic system can only connect to the first and second gears in the forward range, and the automatic transmission can only shift between these two gears, unable to engage higher gears. The upshift is delayed, resulting in naturally stronger power. When shifting from D gear to S gear, there will be a noticeable downshift phenomenon. This forced downshift is to obtain greater output torque, making the car feel more 'powerful'.
