What does the S gear in an automatic car mean?

The S gear in an automatic car refers to the Sport mode, where 'S' stands for Sport. In this mode, the transmission can shift freely, allowing the engine to maintain higher RPMs for extended periods. This enables the vehicle to operate at lower gears with higher revolutions, resulting in greater torque output and acceleration. When using the S gear, the increased RPMs lead to changes in the engine's fuel injection, providing more power but also increasing fuel consumption. Compared to the D (Drive) gear, the S gear is less fuel-efficient due to prolonged operation at lower gears with higher revs, though it offers better performance. Therefore, the S gear is commonly used for overtaking, after which drivers typically switch back to D gear. Some drivers also engage the S gear to help remove carbon deposits by temporarily increasing engine load and raising temperature, which can aid in clearing carbon buildup.
I've been driving an automatic transmission car for several years, and the S gear stands for Sport mode. When I shift the gear to S, the car delays gear shifting, keeping the engine RPM at a higher level, which makes acceleration particularly fast, especially useful when overtaking or climbing steep hills. I remember once on the highway when I needed to overtake a large truck, I switched to S gear, stepped on the gas, and the car surged forward—much more exhilarating than using D gear normally. However, this does increase fuel consumption a bit, so I generally only use it when needed and stick to D gear for better fuel efficiency. New drivers should note that S gear delivers a more aggressive power output, so it's best not to experiment with it casually at first, as it can be harder to control. Overall, this feature makes driving more fun, but it's important to switch flexibly based on road conditions, with safety as the top priority.
As a car enthusiast, I often study various gear positions. The S gear stands for Sport mode. It alters the transmission logic by intentionally delaying upshifts, allowing the engine to rev up faster and deliver stronger horsepower output. It's perfect for occasions when pursuing driving excitement, such as when I'm speeding on suburban roads or playing around with friends. However, this comes at the cost of significantly increased fuel consumption and potentially faster engine wear. I recommend using it only for short bursts of acceleration; for long-distance driving, the D gear is more economical. Additionally, some cars combine the S gear with manual mode for semi-automatic shifting, which adds a lot of fun. Remember, different brands have different tuning, so trying them out will reveal the differences.
I'm older with extensive driving experience, and the S gear stands for Sport mode. When engaged, the car won't shift gears too early, allowing higher RPMs for faster acceleration. In my younger days, I often used it on mountain roads for uphill climbs, but now I prefer the convenience of D gear for simplicity. S gear is recommended only for specific road conditions, and beginners should avoid reckless attempts as poor control can easily lead to accidents. Maintaining steady driving is most important.
