What Happens If You Suddenly Shift to First Gear at 130 km/h?

[DiBrandon]

Driven wheel speed will suddenly decrease, causing the driven wheels to slip against the ground, leading to loss of vehicle control and severe engine wear. The following details are provided: 1. Speed difference: Generally, the speed ratio between the highest and lowest gears in a transmission differs by approximately 4-6 times. The engine redline is typically around 7000 rpm. 2. High wear: In neutral position, even if the engine is revved, the engine speed will not exceed 7000 rpm. This is the high wear zone for the engine; otherwise, it can easily cause engine damage. Therefore, the factory has set the maximum engine speed at 7000 rpm or below 6500 rpm, beyond which fuel supply will be cut off.
