What is the recommended speed for a new car on the highway?
2 Answers
During the break-in period of a new car, it is appropriate to drive at 80 km/h on the highway. Below are the precautions for the break-in period of a new car: Avoid high-speed driving: Try not to let the car's speed reach 120 km/h, as this helps maintain the engine's performance and prolong its lifespan. Avoid overloading: Carrying excessively heavy loads during the break-in period puts unnecessary stress on the car. Overloading requires frequent gear changes, and the constant shifting between high and low gears can be very harmful to the engine. Avoid driving on extremely poor road conditions: Driving on very rough roads during the break-in period causes significant tire wear. Prolonged driving under such conditions with the engine constantly operating at high power can lead to damage.
You really need to pay attention when driving a brand-new car on the highway. Last time I drove my friend's new car back to my hometown, I did some research on this. Actually, the engine of a new car hasn't fully broken in yet, so it's better to keep the speed around 100 km/h, and don't exceed 120 km/h even when overtaking occasionally. The most important thing is not to rev the engine too high—try to keep it below 3,000 RPM, otherwise it could damage the engine. I deliberately avoided using cruise control the entire trip and stopped at service areas every two hours to let the car rest. Also, pay attention to the tire pressure—it's sometimes a bit high when the car first leaves the factory, so it's best to adjust it to around 2.4 bar for long-distance driving.
