What is the introduction of car gears?

[OCatherine]

There are 5 gears in a car, namely first gear, second gear, third gear, fourth gear, and fifth gear. Different gears correspond to different speeds, and the shifting timing varies, requiring careful distinction. Below is a detailed introduction to car gears: 1. Speed range: First gear corresponds to a speed of 0-5km/h. Second gear corresponds to a speed of 5-20km/h, third gear to 20-40km/h, fourth gear to 40-60km/h, and fifth gear to 60-100km/h. 2. Shifting timing: Generally, the shifting timing for most cars is when the engine speed reaches 2000r/min, and should not exceed 2500r/min. For some high-displacement and high-power engines, shifting can be done around 3000r/min.
