Can I Use S Gear on the Highway?

[JulianDella]

You can use S gear on the highway, but it is not recommended to drive at high speeds for extended periods in S gear. This is because S gear only delays upshifting without altering other operational aspects, which inevitably increases the transmission load in the short term, raises the temperature, and accelerates wear and tear. Additionally, vehicle comfort is slightly reduced in S gear mode, so it's best to avoid prolonged use of S gear. Additional Information: 1. S stands for "sport," which is the car's sports mode. When the gear is shifted to S mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPMs for a longer period. This allows the car to operate at low gears with high RPMs for an extended time, resulting in greater torque output and acceleration. 2. Due to its strong power, S gear is typically used for overtaking or climbing hills. After completing these actions, it is advisable to switch back to the more economical D gear. From a fuel consumption perspective, S gear mode consumes significantly more fuel than normal mode because of the increased fuel injection at high RPMs. It also tends to wear out the transmission more quickly, making it unnecessary for everyday driving.
