How to use s file

When the car is running, just push the gear handle directly to the "S" position.

S-gear is the movement mode of the car ("S" is the abbreviation of "sport"). Many automatic cars are equipped with S gears, and some high-profile models of A-class cars also have S gears. In the S-range motion mode, the gearbox can shift gears freely, but the shift timing is delayed, which makes the engine keep high speed for a long time, and makes the car drive at low speed and high speed for a long time, thus obtaining greater torque output and acceleration.

The latest statistics show that every five people have a private car. While cars are widely used in ordinary families, the popularization of automobile knowledge is becoming more and more important. Many car owners often make a lot of jokes in their daily lives because they don't understand cars, just like these misunderstandings about S files. In fact, the S file is what we call sports.

In the S-range motion mode, the gearbox can shift gears freely, but the shift timing is delayed, which makes the engine maintain a high speed for a long time and immediately output a large torque, which increases the power of the vehicle. Generally speaking, like ordinary automatic transmission or CVT models, the rotation speed is kept at about 2000 rpm, and when it comes to S gear, the shift timing will generally be delayed until the engine runs best. If the vehicle with shift paddles is killed in the speed red zone.

When S gear is used, the fuel injection quantity of the engine changes, and the strength increases with the increase of speed. At the same time, the suspension becomes tougher than usual, so the roll will be reduced when cornering, and the brakes will not nod too much. Of course, the comfort in S mode is worse.

From this point of view, the S file is neither a "climbing file" or a "downhill file" as netizens said, nor a "snow mode". The so-called climbing downhill gear refers to the L gear of some cars with automatic manual transmission, which changes the power output of the engine by manual downshifting, thus increasing the power.
