What are the full names of the gear positions P, R, D, and S?

[McFinley]

P stands for Parking gear, R for Reverse gear, D for Drive gear, and S for Sport mode. The specific introductions are as follows: 1. P (Parking) gear: This is a very commonly used gear. When you have parked your car, you must remember to shift into this gear. The parking brake will lock the output shaft, preventing the vehicle from rolling. 2. R (Reverse) gear: This gear can only be engaged when the vehicle is stationary and the engine is idling. 3. D (Drive) gear: In this gear, the car's transmission can automatically shift between various gears. The D gear is the most commonly used driving position. The numbers 1, 2, and 3 following D represent Drive gears 1, 2, and 3, respectively. In this gear, the transmission automatically switches between gears 1 to 3 and does not shift up to gears 4 and 5. It can be used as a limiting gear when traffic is not very smooth, avoiding the skip between gears 3 and 4. 4. S (Sport) mode: In this mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer time to promptly deliver high torque, increasing the vehicle's power for instant acceleration.

I've noticed many people are curious about the letters on car gear shifts. As a long-distance driver, I've personally experienced: P stands for Park, meaning the parking gear, which locks the transmission to prevent rolling when parked; R stands for Reverse, used for backing up when reversing; D is Drive, indicating the driving gear, the default state for moving forward; S refers to Sport mode, used for sporty driving to enhance performance. In daily use, for example, shift to P after parking and then turn off the engine to ensure safety; always check your surroundings before shifting to R to avoid collisions; use D for commuting for comfort and fuel efficiency; use S for mountain roads or overtaking for a thrilling acceleration. Remember, incorrect operations like shifting while moving can damage the transmission. I recommend beginners practice the gear-shifting sequence in an open area first. Although each gear is small, using them correctly can extend the car's lifespan and reduce repair costs.

When I first got my driver's license, I didn't understand these letters. P stands for Park, used for parking in a fixed position; R is Reverse, representing backing up; D means Drive, to be engaged before driving; S is Sport mode for enhanced performance. During driving lessons, the instructor emphasized: always shift to P and engage the parking brake when parked - safety first; shift to R for reverse only after the car has completely stopped and always check rear mirrors; D gear is for smooth daily driving; use S gear sparingly on highways or uphill climbs to save fuel. As a beginner, I practiced frequently: shifting from P to D after starting the car to drive away, and returning to P when parking to ensure stability - now I'm much more proficient and no longer nervous about shifting incorrectly. The key lies in small details, as incorrect operations might trigger alarms and affect the driving experience. I keep a gear explanation sticker in my car to remind myself and passengers to be extra careful.

I am passionate about studying automotive principles, and the full names of the gears are straightforward: P stands for Park, which locks the transmission; R is Reverse for controlling backward movement; D represents Drive for maintaining forward motion; and S refers to Sport for optimized performance. In automatic transmissions, electronic programming is utilized—for example, the S gear delays upshifting to increase engine RPM, making it suitable for spirited driving. Understanding the technical aspects makes maintenance easier: proper use of the P gear reduces wear, the D gear is efficient, and the S gear should be used sparingly to conserve resources when unnecessary. I believe the basics, though simple, are practical—improper operations like quickly shifting to R can damage components, so it's best to focus on gear shifts while driving and adjust according to road conditions.
