What is the speed limit during the break-in period of a motor vehicle?

[LaChloe]

The speed limit during the break-in period of a motor vehicle varies depending on different stages: 1. In the initial stage of the break-in period, maintain a speed between 60 to 70 km/h, with the engine speed not exceeding 2200 rpm; 2. In the middle stage, the speed can be increased to 90 to 100 km/h, keeping the engine speed below 2500 rpm; 3. In the later stage, the speed can be raised to below 120 km/h, with the engine speed not exceeding 3000 rpm. The break-in period refers to the initial driving period after a new vehicle leaves the factory, during which the engine components are allowed to wear in smoothly. Precautions during the break-in period include: 1. Maintain smooth starts, avoid sudden acceleration, and prevent the engine from running at excessively high speeds; 2. Before starting, ensure the coolant temperature reaches at least 50 degrees Celsius, and start in a low gear.
