What does the DS gear mean in an automatic transmission car?

[OBarrett]

D gear is the drive gear, also known as the forward gear, used when moving forward. S stands for Sport mode. When this gear is engaged, the transmission can shift freely, but the shift timing is delayed, keeping the engine at high RPM for a period to increase the car's power. Generally, automatic transmission cars have six gear positions from top to bottom: P, R, N, D, S, L. Here are the details: 1. P gear: Parking gear, used when the vehicle is parked and not in use. The wheels are mechanically locked to prevent rolling. 2. R gear: Reverse gear, used when reversing. 3. N gear: Neutral gear, used for temporary stops (e.g., at a red light). Note that this gear indicates neutral, and to prevent the vehicle from rolling on a slope, the brake must be applied. 4. L gear: Low gear. When going downhill or on a long slope, engaging this gear limits the car to the lowest gear (equivalent to first gear in a manual transmission car), allowing the engine to assist in braking, reducing the need for prolonged brake use and preventing brake overheating and potential hazards.
