Can the car stay in sport mode? Is it harmful to the engine gearbox?

For an automatic car, after starting the sports mode, the car becomes violent, the reaction is accelerated, the power is on call, the performance is improved, and it is more fun to drive.

However, after starting the sports mode, it has little influence on the engine, and the load of the high-speed shift engine is smaller. However, the speed of the gearbox only increases, which will not increase the wear, and the load of the gearbox will also decrease after the shift delay. The damage to the engine gearbox comes from violent driving. For example, the floor oil is started, and the floor oil is often braked suddenly and accelerated. In this case, the engine often works under high load, which has a great impact on the gearbox, and the life of the engine gearbox will be shortened under such intense operation.

Sports mode is also called S-block, which is different from D-block. In most cases, it can be a D to the end. If you want to experience the driving pleasure brought by power, you can hang the S file. For example, for a short overtaking, putting S gear can make you more confident and accelerate faster. In some cases, it can be said that safety has improved, and shorter overtaking time means safer. Of course, security is relative, not absolute. The difference between S block and D block is only control logic. After the S gear is engaged, the engine will become sharper, the dynamic response will be faster, and the accelerator pedal signal will be amplified. At the same depth, the throttle opening will be larger when the S gear is engaged. The performance of the D-block engine is mediocre, mainly from the perspective of economy and safety. After all, the engine is too violent and the throttle is too sensitive, which will lead to difficulties in vehicle control and micro-operation.

When the S gear is engaged, the shifting logic of the gearbox will also change accordingly. The shift logic of automobile gearbox affects fuel consumption and ride comfort to some extent. In order to take care of fuel consumption, the speed of gearbox upshift should not be too high, and some models even have the feeling of grabbing gears. Active upshifting leads to poor power experience, engine power is suppressed, and low-speed and high-speed engines have light load, so the response is faster. However, after the upshift, the instantaneous load of the engine will increase, and the engine power will be suppressed. Only when the engine speed increases can the power be released. It's like boiling water. After boiling, add a little cold water and the boiling will stop. After switching into the S gear, the shift of the gearbox will slow down.

The shift is delayed, and it will keep running at high speed in the current gear for a period of time after shifting. In this way, more torque and acceleration can be obtained, resulting in a push-back feeling, faster dynamic response, more power and a "sense of movement".

It can be seen that the S gear is mainly to improve the handling, make the car more passionate, more fun and more fun to drive. However, it is not recommended to use S gear for a long time. After all, it will affect the fuel consumption of the car and lead to an increase in the fuel consumption of the car. The influence of S gear on the engine is that the working time will increase at high speed, and theoretically the engine wear will also increase. But as long as it is not violent driving, the influence of S gear on the engine can be ignored. The impact on the gearbox is that the low-speed gear speed is slightly higher than usual, but it has little effect on the service life. Under the condition of normal lubrication/heat dissipation, the damage of gearbox can be ignored!
