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

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.
A few days ago, I happened to research the DS gear while helping a friend check out a car. Actually, the 'S' stands for Sport mode. When you shift to DS gear, the car becomes noticeably more responsive, with the engine RPM consistently maintained at a higher level. I tried switching to DS gear when overtaking on the highway—stepping on the gas made the car surge forward instantly, packing a real punch. Of course, the trade-off is about a 10% increase in fuel consumption. For everyday city driving, the regular D gear is perfectly comfortable, but DS gear really comes in handy when you need quick acceleration or to climb steep hills. Just remember not to keep it engaged for too long, as it can lead to increased engine carbon buildup.
My car has a DS mode, and the driving experience is noticeably different. In regular D mode, the transmission shifts gears below 2000 rpm to save fuel. But when switched to DS mode, the gear shifting is delayed, keeping the revs above 2500 rpm, ready for you to step on the throttle. Last month on a mountain road, I was stuck behind a slow-moving truck, but switching to DS mode made overtaking effortless. Just remember to switch back after using it—once I forgot and drove 20 km in DS mode, and the fuel consumption increased by nearly 2 liters. With fuel prices so high, it really hurts the wallet.
