Does a new car need a break-in period? Is high-speed running necessary?

[Millie]

New cars require a break-in period and high-speed running. Break-in principle: The reason for the break-in practice for new cars is primarily because each automobile consists of thousands of metal components. The break-in period for the powertrain is typically 1,500 kilometers. The brake system break-in is particularly crucial. Generally, new cars should be driven cautiously within the first 600km, as new tires require at least 200km of driving friction to achieve optimal traction. Similarly, brake pads need approximately 400km of driving to reach ideal friction levels. High-speed running: High-speed running mainly targets the engine. After the initial break-in period, the operation between engine components becomes more coordinated. Maintaining high-speed operation for a period allows testing of the machine's extreme working conditions and expands the tensile, compressive, impact, and torsional resistance ranges of component materials.
