What is the function of the S gear in Volkswagen Passat?
2 Answers
The function of the S gear in Volkswagen Passat is as follows: 1. Output powerful power: In S gear sports mode, the transmission can shift freely, but the shifting timing will be delayed, keeping the engine at high speed for a longer time, allowing the car to move at low gear and high speed for a longer time, thereby obtaining greater torque output and acceleration. 2. Reduce carbon deposits: Cars that drive in congested urban areas for a long time will have more carbon deposits in the engine. Therefore, using the S gear appropriately and regularly is beneficial for removing carbon deposits in the engine, increasing fuel economy, and extending the engine's lifespan.
I've been commuting with my Passat for six or seven years, mostly using the D gear, but I switch to S gear when I need more power. After shifting to S gear, the car feels like its sporty nerves are activated, with noticeably higher RPMs, and the throttle delivers power much quicker, making it especially effective for overtaking. For example, when encountering slow-moving vehicles on the highway, switching to S gear and stepping on the throttle allows for a clean and swift overtake. However, using S gear in the city isn't very cost-effective, as fuel consumption increases by at least 20-30% compared to normal driving, and the engine noise becomes louder. Prolonged use can also easily cause the transmission to overheat. Therefore, I usually only switch to S gear when climbing hills or when I urgently need to accelerate, switching back to D gear afterward. This feature adds a bit of excitement to the Passat's otherwise steady demeanor.
