What happens if an automatic transmission car is always driven in S mode?

[OBradley]

Driving an automatic transmission car in S mode all the time will not cause damage to the car, but it will increase fuel consumption and raise the engine temperature. S mode refers to the sport mode of the car. After activating sport mode, the transmission can still shift automatically, but the shifting timing is delayed, keeping the engine at higher RPMs for a longer period. The transmission will downshift, allowing the car to gain greater torque and faster acceleration. S mode is typically used when climbing hills or overtaking. Since S mode only delays the upshifting of the transmission without altering other operational aspects, using it will increase the transmission's load and temperature in the short term, leading to some degree of wear on internal components.
