Can the Audi S gear be used frequently?

Audi S gear can be used frequently, but it is not very economical. Here are some related introductions about the S gear: 1. The function of S gear: In S gear sports mode, the transmission can shift freely, but the shifting time will be delayed, keeping the engine at high speed for a longer time, allowing the car to travel at low gear and high speed for a longer time, thereby obtaining greater torque output and acceleration. 2. The use of the lock button: To shift from D gear to S gear, you need to press the lock button on the gear lever; but to shift back from S gear to D gear, you can directly shift back without pressing the lock button.

When I first bought my Audi, I was also curious about whether the S mode could be used daily. After driving it for three years, I’ve figured it out. The S mode is essentially the sport mode—it delays upshifting to keep the engine at higher RPMs, making the throttle response sharper. When overtaking, the acceleration pushes you back into the seat instantly. However, prolonged use of S mode keeps the engine RPMs consistently high, and the transmission frequently holds lower gears. In city traffic, fuel consumption can be 2-3 liters higher than in D mode, and engine noise becomes noticeably louder. I usually only switch to S mode for spirited mountain driving or highway overtaking. For daily commutes, D mode is much more comfortable, with the engine running as smoothly as if it were soundproofed.

Using S mode comes with an economic cost. Last week on the highway, I specifically tested it - on the same stretch of road, D mode cruise consumed 7.8L/100km, while switching to S mode immediately jumped to 9.5L/100km, with the fuel gauge visibly dropping faster. The dealership technician warned that prolonged high-RPM operation accelerates engine carbon buildup and affects spark plug lifespan. However, Audi's transmission is indeed intelligent; its downshift rev-matching in S mode is as decisive as a cheetah pouncing on prey. My current habit: sunny mountain roads call for S mode to enjoy driving pleasure, while rainy traffic jams mean switching back to D mode for fuel efficiency and peace of mind.

Driving in the city with the S-mode is actually quite tiring. When stuck in traffic at Jianguomen in the morning, I tried the S-mode—the engine kept hovering around 3000 RPM, the buzzing sound giving me a headache, and the car always nodded when braking. But last week, driving on the mountain roads in Huairou was like discovering a whole new world: locking the S-mode in 2nd gear for hairpin turns, the throttle responding instantly, and the addictive popping sound of exhaust backfire when exiting the turns. However, I wouldn’t recommend using it continuously for more than an hour. Once on the track, I noticed the transmission temperature was 15°C higher than usual, and a yellow warning light popped up on the dashboard.

When you want to drive your Audi like a hot hatch, switching to S mode is definitely the right move. I've tested the difference between D and S modes in an underground garage—with the same half-throttle input, D mode feels like a sluggish sloth, while S mode is like a hound that's been kicked in the rear. However, continuous use of S mode makes the transmission shifts feel more frequent and jerky, especially the lurch during the 2nd to 3rd gear shift. A friend at a tuning shop mentioned that prolonged high-load driving could shorten the clutch plate's lifespan—he's seen aggressive S3 drivers needing clutch replacements as early as 50,000 km. Now, I regularly use fuel additives to clean carbon deposits and only switch to S mode for weekend mountain runs. For daily commuting, it's better to drive gently.

Veteran drivers talk about the dual nature of the S mode. Once during a heavy rain on the highway while overtaking a large truck, the car in D mode slowly accelerated with no real power, but switching to S mode instantly dropped two gears, and the surging power pulled the car body swiftly past the truck—I genuinely felt that feature saved my life. However, last winter I got lazy and used S mode for my entire commute, only to find at the end of the month that I spent an extra 500 bucks on gas. At the repair shop, they showed me the severely carbon-fouled spark plugs at just 30,000 km, and the mechanic held up the blackened electrodes, saying, 'This thing burns up like it's drinking an '82 Lafite—way too fast!' Now I treat S mode like an emergency button—turn it on when I need some excitement, but stick to D mode for everyday comfort.
