Why Downshift for Overtaking?

[DiZane]

Downshifting for overtaking is done to obtain greater power. The moment the gear is downshifted, the engine speed immediately increases while the vehicle speed remains unchanged. Due to the increased transmission ratio, the torque output from the engine to the wheels also becomes greater. After completing the downshift operation, the vehicle typically decelerates by reducing the throttle (so-called deceleration downshifting). Because the torque output increases, continuing to press the accelerator will generate significant acceleration, allowing the vehicle to speed up quickly. Overtaking refers to the process where the following vehicle changes lanes to the rear side of the leading vehicle, passes it, and then returns to the original lane. The lane usually used for overtaking is the inner lane, which is closer to the center of the road and farther from the shoulder.
