What is the recommended speed for a new car during the high-speed break-in period?

[VanCorbin]

During the break-in period of a new car, the speed should generally be maintained between 30-90 km/h, and the engine RPM is best kept between 2,000-2,500, not exceeding 3,000 RPM. Controlling the engine RPM is more critical during the break-in period. Here are some additional details: 1. Generally, the break-in period is divided into three stages: initial, middle, and late. During the initial stage, the maximum speed should be kept around 40 km/h; in the middle stage, on roads with good conditions, the maximum speed can be increased to 60 km/h; by the late stage, it can be raised to around 80 km/h. Maintaining a moderate speed during the break-in period is essential—speed should not be too high or too low, as excessively low speed can increase fuel consumption. 2. Speed limits are essentially limits on engine RPM. During the break-in period, it is crucial to control driving speed and avoid excessively high speeds. After driving 1,500 km, you can gradually increase the RPM and speed to the vehicle's maximum allowed speed, but avoid pressing the accelerator too hard to ensure that pistons, cylinders, and other important components increase their load in a gentle state.
