Can a Newly Purchased Car Drive on the Highway?

Newly purchased cars can drive on the highway. Precautions for driving on the highway include: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle ahead, the turn signal must be activated in advance; 4. Only use adjacent lanes for overtaking, and immediately return to the driving lane after overtaking. Vehicles must not straddle or ride on lane dividers; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, conduct test drives or drive training vehicles, or overtake or park on ramps; 6. Maintain a following distance of at least 100 meters. When the speed is below 100 km/h, the distance from the vehicle ahead in the same lane can be appropriately reduced, but the minimum distance should not be less than 50 meters.

I drove my brand-new car directly onto the highway to return to my hometown on the day I picked it up last year, and it was completely fine! Nowadays, cars undergo cold running-in at the factory, and driving on the highway actually helps with even break-in. Just avoid speeding over 100 km/h and don't keep the RPM at the same value constantly. Make sure to check tire pressure and fluid levels beforehand, and avoid slamming the accelerator or brakes hard within the first 300 kilometers. A mechanic friend of mine said that moderate high-speed operation is actually better for break-in than stop-and-go city driving. Long-distance driving also helps test the vehicle's stability—like how I noticed the steering wheel was slightly off to the left after my trip and had it adjusted during the first service.

Of course, a new car can be driven on the highway, but take it easy. When I picked up my car, I specifically asked the 4S shop technician, and he said not to let the engine exceed 3500 rpm continuously for two hours. It's recommended to vary the speed occasionally and avoid using cruise control all the time. It's best not to overload; a fully packed trunk can increase the burden on the brakes. Once, I had a trunk full of New Year goods, and when I stepped on the brake, it felt a bit soft, which scared me into unloading at the next service area. By the way, remember to open the windows to air out the interior smell and check the tires more often at service areas.

It's perfectly fine to drive a new car on the highway during the break-in period, the key is to control the engine speed. For the first 500 kilometers, it's best not to exceed 70% of the redline RPM, maintaining a speed between 90-110 km/h is safest. Last week I just helped my cousin drive his new car home, with ECO mode engaged throughout the journey. The dashboard indicated the optimal gear position, which proved more reliable than relying on an experienced driver's intuition. The transmission shifted just above 2000 RPM, with speed fluctuations kept within ±500 RPM. The onboard computer showed a fuel consumption of only 6.2L/100km, which was even more economical than taking national highways.
