What do E and S stand for in an automatic transmission car?

[LaIsabelle]

E stands for Economy mode, which is suitable for urban driving, such as during traffic jams. S stands for Sport mode, which is more appropriate for use on highways. Generally, automatic transmission cars have six gear positions, with the following explanations: 1. P (Parking): The parking gear, also the starting position. In this mode, 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). Note that this gear indicates neutral; to prevent the car from rolling on a slope, the brake must be engaged. 4. D (Drive): The forward gear, also known as the driving gear. This is used when the car is moving forward. 5. L (Low): The low gear. When going downhill or on a long slope, shifting to this gear restricts the car to the lowest gear (equivalent to first gear in a manual transmission), allowing the engine to assist in braking. This prevents the brake pads from overheating due to prolonged braking, which could be dangerous. 6. S (Sport): Indicates Sport mode. When engaged, the gear can shift freely, but the shift timing is delayed to keep the engine at higher RPMs for a period, enhancing the car's power.
