What Are the Gears in an Automatic Transmission Car?
1 Answers
Automatically transmitted cars mainly have gears such as P, R, N, D, L, S, and M, each representing different functions. Here is a detailed introduction: P - Parking Gear: When the car is parked and not in use, the gear is set here. At this time, the wheels are mechanically locked to prevent rolling; R - Reverse Gear: Used when the car is reversing; N - Neutral Gear: Used for temporary stops (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; D - Drive Gear: Used when the car is moving forward; L - Low Gear: When going downhill or on a long slope, setting the gear here restricts the car to the lowest gear (equivalent to first gear in a manual transmission car), allowing the car to use engine power for braking. This prevents the driver from having to press the brake for extended periods, which could overheat the brake pads and cause danger; S - Sport Mode: When this gear is engaged, the gears can be freely switched, but the shifting timing is delayed, keeping the engine at high RPM for a period to increase the car's power. This gear will result in higher fuel consumption; M - Manual Mode: Engaging the M gear switches to manual mode, requiring manual gear shifting. Manual mode is generally used when going uphill or downhill, overtaking, starting on icy or snowy roads, or in traffic jams. When the M gear is engaged, there are no time or RPM restrictions, and the transmission will automatically match the appropriate gear based on the real-time speed of the car.
