What speed can be achieved in 4th gear of a car?
1 Answers
In a car, 4th gear can achieve speeds above 40 km/h. Below is relevant information about car gears: 1. Speed range: First gear corresponds to speeds of 0-5 km/h, second gear to 5-20 km/h, third gear to 20-40 km/h, fourth gear to 40-60 km/h, and fifth gear to 60-100 km/h. 2. Gear shifting timing: For most cars, the optimal gear shifting occurs when the engine reaches 2000 r/min and should not exceed 2500 r/min. For some high-displacement, high-power engines, shifting can be done around 3000 r/min.
