Can You Use S Mode Continuously on the Highway?

[LydiaRose]

You should not use S mode continuously on the highway because the S gear only delays upshifting without changing other operational aspects, which inevitably increases the transmission load in a short time, raises the temperature, and accelerates wear and tear. The comfort of the vehicle in S mode is also slightly worse, so try to avoid prolonged use of the S gear. Due to its strong power, the S gear is generally used when overtaking or climbing hills. After completing these actions, it is advisable to switch back to the more economical D gear. In terms of fuel consumption, since the fuel injection volume increases at high RPM, the S mode consumes significantly more fuel than the normal mode and can also cause additional wear on the transmission, making it unnecessary for daily driving. During driving, the transmission can shift gears freely. However, after switching to sport mode, the shift timing is delayed, keeping the engine at high RPM for a longer time. This allows the car to maintain higher torque output and acceleration in lower gears at higher speeds for an extended period, but it may affect the comfort of the vehicle to some extent.
