Do New Cars Need High-Speed Break-In?

[DeJackson]

With the continuous advancement in automotive manufacturing technology, modern vehicles no longer require extensive break-in periods, let alone high-intensity high-speed break-in. Below are some key considerations for using a new car: 1. Avoid Overloading: Carrying excessive weight during the break-in period can damage mechanical components. Since the powertrain parts haven't fully seated yet, aggressive acceleration may cause irreversible harm. Therefore, the "slow and steady" principle should be followed. 2. Speed Limitations: Domestic vehicles typically have a break-in speed range of 40-70 km/h, while imported vehicles usually recommend staying below 100 km/h. When fully accelerating, the speed shouldn't exceed 80% of the maximum speed. The recommended engine RPM during break-in is between 2,000-4,000 rpm.
