What does the S gear in an automatic car mean?

[JessicaRose]

The S gear in an automatic car stands for Sport mode, which can be directly engaged when the driver needs rapid acceleration or overtaking. Common gears in an automatic transmission include P, N, R, D, L, S, and M, representing: P for Park, N for Neutral, D for Drive, L for Low gear (also known as Hill Climb gear). The steps to start an automatic car are: 1. Insert the key and turn it to the second ignition position (accessory mode), wait for the system self-check to complete; 2. Shift the gear lever from P to N; 3. Release the brake and start the car's engine; 4. Press the brake pedal and shift the gear lever from N to D, then release the brake and press the accelerator to start moving.

The S gear in an automatic transmission car is actually the Sport mode. I often use it in my daily driving, especially when I need to overtake or go uphill. Engaging the S gear keeps the engine RPM in a higher range, shifts gears a bit slower, and delivers stronger power output, giving a noticeable push-back sensation. While the D gear is quite fuel-efficient for regular use, occasionally switching to S gear for some driving fun, like on highways or winding mountain roads, makes the car feel more lively. However, frequent use can increase fuel consumption and may put some strain on the transmission, so it's best suited for short-term scenarios. I’ve also heard it offers some effects similar to a manual transmission but is more convenient, with smooth automatic control. Overall, it’s a practical feature that adds a bit of excitement to the driving experience, though it’s not ideal for frequent use during daily commutes.

The S gear in automatic transmission cars is designed for Sport mode, primarily to enhance acceleration performance. I particularly enjoy using it while driving, especially on mountain roads or race tracks. Engaging the S gear delays the engine's shift points, keeping it in higher RPM ranges for longer periods, resulting in more direct power response and quicker, stronger acceleration for overtaking. Compared to the regular D gear, it makes the car feel more aggressive, making it suitable for situations where a sense of speed is desired. However, this does consume more fuel and slightly increases transmission wear, so it's advisable to control the frequency of use. I also find it somewhat similar to certain racing setups, simulating some of the fun of manual control while remaining simple and automatic. It's also quite useful in situations requiring emergency maneuvers due to its quick response. Overall, it's a great addition to the driving experience, but should be used in moderation to avoid unnecessary extra costs.

The S gear in an automatic transmission car stands for Sport mode, which I frequently use in practice to enhance power. Shifting to S gear keeps the engine at higher RPMs and delays gear shifts, thereby delivering more aggressive acceleration performance. For instance, it shows noticeable effects during overtaking or climbing hills, offering stronger responsiveness compared to D gear. However, this consumes slightly more fuel and increases thermal load, so it's advisable to use it occasionally. Avoid prolonged use of S gear to prevent affecting the car's lifespan. Additionally, it's suitable for sharp turns, aiding in stable driving. Overall, it's a convenient feature for boosting performance.
