What is the appropriate speed for running in a new car?
2 Answers
During the running-in period of a new car, a speed of 50 to 80 kilometers per hour is appropriate. The running-in period refers to the initial period after the car leaves the factory, during which it is driven a certain distance to allow the various engine components to run in smoothly. During the running-in period, the car's components can adapt to their environment, and any protrusions on the parts can be worn down. Precautions for using a new car during the running-in period include: 1. Warm up the engine before starting; 2. Avoid emergency braking; 3. Avoid overloading; 4. Avoid long-distance driving; 5. Avoid high-speed driving; 6. Use high-quality gasoline; 7. Do not remove the speed limiter prematurely; 8. Shift gears in a timely manner; 9. Properly adjust the ignition system and fuel supply system.
I think maintaining a speed between 80 to 90 km/h is quite suitable during the new car break-in period. After all, the engine components of a brand-new car haven’t been properly worn in yet, and driving too fast can cause excessive wear, affecting future performance. I recommend driving gently for the first few hundred kilometers, avoiding sudden acceleration or hard braking, and varying the speed instead of sticking to a constant one. The manual usually suggests a break-in period of 1,000 kilometers, but to be on the safe side, keep it around 60-70 km/h in urban conditions and don’t exceed 100 km/h on highways. Remember to regularly check the engine oil and tire pressure to ensure everything is in order. After the break-in period, the car will run smoother and be more fuel-efficient. In short, steady driving is the wise choice—don’t ruin your new car just for a thrill.
