Can a New Car Be Driven Long Distance on the Highway?

[AvaFitz]

New cars can be driven long distances on the highway. The break-in period for a car refers to the initial driving phase after purchase or major repairs, typically covering 1,000 to 1,500 kilometers. This mileage is essential for ensuring that mechanical components fully contact, frictionally adapt, and settle into their proper form. The break-in period generally describes the process where mechanical parts initially come into contact, rub against each other, and mesh together. During this period, the car's components adjust and enhance their ability to adapt to the environment while wearing down any surface irregularities. The quality of the break-in process significantly impacts the vehicle's lifespan, safety, and fuel efficiency. New transmission components often have minor surface imperfections, leading to less precise contact and meshing during operation, which results in more intense friction at contact points. If operated at excessively high speeds, the elevated friction temperatures or excessive loads can cause permanent damage to the components.
