Pwrmode button indicates power mode. Compared with normal mode, in power mode, the gearbox will delay the upshift and provide more powerful acceleration. Maintaining a certain exhaust pressure at high engine speed can better promote the turbine to obtain better dynamic performance. This model is generally a Japanese car.
In power mode, the owner can obviously feel the power of the car, mainly because the shifting of the gearbox becomes more radical in this mode. In normal mode, the shift can start at 2000 rpm, while in power mode, the shift does not start until 3000 rpm. The shift delay of the gearbox keeps the engine at a high speed and makes the vehicle have better dynamic response.
