What is the difference between D and S gears in an automatic transmission?
4 Answers
The following are the differences between D gear and S gear: 1. D gear stands for Drive gear. The advantage of D gear is that it is more fuel-efficient compared to S gear, but the disadvantage is that it provides less power. 2. S gear is the Sport mode, where the engine runs at higher RPMs, and the transmission shifts up later and down earlier. The advantage of S gear is better vehicle performance, while the disadvantage is poorer fuel economy. It is suitable for overtaking or climbing hills. Below are the methods for switching between different gears in an automatic transmission: 1. Shifting from P to R or R to P requires pressing the shift lock and applying the brake. 2. Shifting from R to N does not require pressing the shift lock or applying the brake. 3. Shifting from N to R requires pressing the shift lock and applying the brake. 4. Shifting from N to D requires pressing the shift lock and applying the brake. 5. Shifting from D to S requires pressing the shift lock, but neither releasing the throttle nor applying the brake is needed. 6. Shifting from S to D can be done by directly pushing the lever, without releasing the throttle or applying the brake.
Hey, the difference between D mode and S mode is quite simple. D mode is the most commonly used driving mode, which automatically shifts gears for you. It's perfect for daily commutes or grocery runs—fuel-efficient and smooth, with lower RPMs. S mode, on the other hand, is the sport mode. For example, when you need to overtake or climb a steep hill, it delays gear shifts to keep the engine RPM higher, delivering stronger acceleration and that thrilling push-back-in-your-seat feeling. The downside is it consumes more fuel, so I rarely use it unless I'm on an open highway or just want to enjoy some driving fun. In short, D mode is the default choice for saving money and hassle, while S mode is reserved for those occasional wild moments.
As someone who loves driving fast, I find the S mode absolutely exhilarating! The D mode is too ordinary, only suitable for slow and steady driving with low RPM and quick gear shifts. But once you switch to S mode, the car feels like it's been activated—delayed gear shifts let the engine roar, and acceleration becomes much quicker, especially when overtaking on highways or mountain roads. I remember using it once on a national highway; the car responded super sensitively and zoomed past in no time. However, it guzzles fuel like crazy, so I only use S mode on weekends when I'm out for fun. D mode is for everyday drivers, while S mode is for those seeking a thrill—give it a try!
There is a noticeable difference in fuel consumption between D mode and S mode. D mode is the normal driving mode where the transmission system shifts gears intelligently, maintaining lower RPMs and consuming less fuel, allowing you to travel farther on a full tank. When S mode is engaged, the system keeps the engine at higher RPMs, making it work harder, which can increase fuel consumption by 1-2 liters per 100 kilometers. Over time, this can significantly raise fuel costs. Therefore, if I were driving, I would prioritize using D mode to save money and be more environmentally friendly. S mode should only be used when necessary, such as when climbing steep hills or needing to overtake in urgent situations. Remember, choosing the right driving mode is beneficial for both your wallet and the environment.
