What is the minimum speed for 2nd gear in a car?

[DelDante]

The minimum speed for 2nd gear in a car is 10 kilometers per hour. If the speed is less than 10 km/h, continuing to drive in 2nd gear may easily cause the engine to stall. The engine shifting data is as follows: In 1st gear: The engine speed is around 1000-1500 rpm, the vehicle speed is 10 km/h, then shift to 2nd gear. In 2nd gear: Press the accelerator, the engine speed is around 1500-2000 rpm, the vehicle speed reaches 30 km/h, then release the accelerator and shift to 3rd gear. In 3rd gear: Press the accelerator, the engine speed is around 1500-2000 rpm, the vehicle speed reaches 40 km/h, then release the accelerator and shift to 4th gear. In 4th gear: Press the accelerator, the engine speed is around 1500-2000 rpm, the vehicle speed reaches 50-70 km/h, then release the accelerator and shift to 5th gear. In 5th gear: Press the accelerator, the engine speed is around 1500-3000 rpm, the vehicle speed reaches 80-120 km/h.
