Should You Use Third or Fourth Gear at 40 km/h?
1 Answers
It is best to use third gear when driving at 40 km/h, otherwise it may damage the car's engine and transmission. Here is a detailed introduction about car gears: 1. Speed range: First gear corresponds to a speed of 0-5 km/h. Second gear corresponds to 5-20 km/h, third gear corresponds to 20-40 km/h, fourth gear corresponds to 40-60 km/h, and fifth gear corresponds to 60-100 km/h. 2. Gear shifting timing: Generally, the optimal time to shift gears is when the engine speed reaches 2000 r/min, and it should not exceed 2500 r/min. For some high-displacement and high-power engines, shifting can be done around 3000 r/min.
