What does DS mean when it appears in an automatic transmission?

[JuliaAnn]

D stands for Drive, also known as the driving gear, used when moving forward. S stands for Sport mode; when this gear is engaged, the transmission can switch freely, delaying the shift timing to keep the engine at high RPM for a period, thereby increasing the car's power. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L. Specific details are as follows: 1. P—Parking, the parking gear, also the starting gear. When the car is not in use, the wheels are mechanically locked to prevent rolling. 2. R—Reverse, the reverse gear, used when backing up. 3. N—Neutral, the neutral gear. Used when temporarily stopping (e.g., at a red light). This gear indicates neutral; to prevent the car from rolling on a slope, the brake must be engaged. 4. L—Low, the low gear. When going downhill or on a long slope, engaging this gear allows the car to use engine braking, preventing the driver from having to brake continuously, which could overheat the brake pads and cause danger.
