Why Do New Cars No Longer Require a Break-in Period?

[RiverAnn]

Because modern automobile manufacturing processes and technologies have significantly improved, new cars today no longer require a break-in period. Below is relevant information regarding precautions for using a new car: 1. Avoid overloading: Carrying excessive weight during the break-in period can cause damage to mechanical components. Since the power transmission parts of a new car have not yet fully worn in, aggressive acceleration may cause irreversible damage to the vehicle. Therefore, it is essential to adhere to the principle of "slow and steady" during the break-in period. 2. Speed limits for new cars: Domestic cars generally have a speed limit of 4070 km/h, while imported cars usually have a limit of 100 km/h. When the throttle is fully open, the speed should not exceed 80% of the maximum speed. The engine speed during the break-in period is typically specified to be between 20004000 rpm.
