How long does it take for a new car to be driven on the highway?

A new car can be driven on the highway at any time, just avoid letting the engine run at excessively high RPMs during the journey. New cars have a break-in period right after purchase, during which they can be driven at high speeds as long as the engine is not operated at excessively high RPMs. Running the engine at high RPMs during the break-in period can increase engine wear. After the break-in period, it is recommended to drive the car at high speeds to enhance engine performance. This is because, after the initial break-in, the components of the new engine operate more harmoniously. Driving at high speeds for a period allows testing the engine's extreme working conditions and expands the tensile, compressive, impact, and torsional resistance ranges of the components.
When you first get a new car, it's best not to rush onto the highway. Give it some time to break in. From my years of driving experience, the engine and transmission need about the first 1,500 kilometers to adapt—avoid high RPMs or prolonged high-speed driving. Driving slower on the highway is fine, but try not to exceed 100 km/h to protect components and extend the car's lifespan. Before hitting the highway, do a quick check: ensure tire pressure is normal and the braking system is stable. Modern cars have more lenient break-in requirements, but it's still safer to follow the manual. If you must take the highway early, use lower gears and avoid sudden acceleration. Also, new tires have less grip, so be cautious when turning. Safety first—wait until after the break-in period to push the car's limits on the highway.
