How many kilometers can a new car run on the highway?

For a brand-new car just off the lot, it's best not to drive on the highway during the break-in period. In principle, within the first 2,500 kilometers, the engine speed should not exceed 2,500 rpm. Most new cars during the break-in period are advised not to exceed 100 km/h in speed, keep the engine speed below 3,000 rpm, and avoid aggressive driving, sudden acceleration, or hard braking. Maintain a steady speed: The key during the break-in period is to drive at a steady speed, avoiding rapid acceleration or braking, and high-speed rotations. Once the break-in period is over, it's necessary to take the car for a highway run. Watch for component damage: Pay attention to any unusual noises, as they may indicate installation or configuration issues with certain components. Remember to address these issues for free during the first maintenance service, as some parts may not be covered for free repairs if damaged after this period.
From a mechanical perspective of automobiles, it's crucial to be cautious about how many kilometers a new car is driven on the highway. The break-in period, typically within the first 1,600 kilometers, is particularly critical as the internal components of the engine need to gently align with each other. Driving at high speeds, too fast, or for excessively long distances right from the start can accelerate wear and affect the vehicle's lifespan. I recommend keeping highway speeds between 80-100 km/h and limiting continuous driving to no more than 800 kilometers at a time. For example, after driving gently on the highway for about two hours, take a break to allow the engine to cool down. This approach not only protects the new car but also ensures long-term performance stability, preventing issues like increased engine noise or higher fuel consumption. Remember to check the manual, as different brands may have varying guidelines.
As an average car owner, I used to be hesitant about taking my brand-new car straight onto the highway for high-speed driving. The manual states there's a break-in period of approximately 1,500 kilometers, during which it's best to keep highway trips relatively short—for example, no more than 500 kilometers at a time—and avoid exceeding speeds of 100 km/h. Here's how I handled it: For the first few months with the new car, I limited my highway commutes to round trips of 300-400 kilometers, relying on national roads or city driving to cover the remaining distance. This approach resulted in smooth vehicle performance with no mechanical issues. Pushing a new car too hard on the highway can cause excessive friction between new components, increasing the risk of future repairs. In short, don't neglect the break-in period just to save time—taking it slow brings peace of mind.
