Why Shouldn't You Upshift When Overtaking?

[LondonAnn]

Because the moment you upshift, the engine RPM immediately drops while the vehicle speed remains unchanged. Simultaneously, due to the reduced transmission ratio, the torque output from the engine to the wheels also decreases. After completing the upshift, although you can accelerate by pressing the throttle, the reduced torque output results in slower acceleration. Precautions for downshifting before overtaking: 1. Do not use downshift overtaking when the current gear has already reached its maximum speed or when the current speed exceeds the maximum speed of the lower gear. 2. If the current gear still has sufficient acceleration capability or the current speed is already adequate to overtake the target vehicle within a short time, downshift overtaking is unnecessary. 3. Although downshift overtaking can shorten the overtaking process, frequent use of this method will increase fuel consumption.
