Is Downshifting Immediately Necessary When Decelerating?

[ColeDella]

No. When driving, it is possible to decelerate without downshifting, which can be achieved in vehicles with larger displacement and lighter loads. The correct gear can be gradually adjusted after the speed has finally decreased. Since speed and gear must be well-matched, it's best to shift up or down to the correct speed. Gear shifting considerations: 1. Gear matching: The allowable range for first gear is 0~20, shifting to second gear is appropriate at 15~20; the allowable range for second gear is 10~30, shifting to third gear is appropriate at 25~30; the allowable range for third gear is 20~40, shifting to fourth gear is appropriate at 35~40; the allowable range for fourth gear is 30~50, shifting to fifth gear is appropriate at 45~50. 2. Smooth shifting: Strive for smooth shifting; you can shift gears as soon as the speed (RPM) is reached, avoiding gear disengagement.
