What is the best speed to drive during the car break-in period?
2 Answers
During the car break-in period, it is generally best not to exceed 80 km/h. The break-in period for a new car is typically around 2,000 kilometers, during which the performance of the car's engine is being conditioned. It is important to properly handle all aspects of the car's break-in during this time. Below are detailed explanations and precautions for different types of new cars during the break-in period: 1. Domestic cars: For domestic cars, the recommended speed during the break-in period is 40-70 km/h. 2. Imported cars: For genuine imported cars, it is best to drive at 100 km/h, with the engine speed maintained between 3,000-4,000 rpm. Avoid prolonged high-speed driving. 3. Precautions: Long-distance driving during the break-in period can increase the continuous working time of the engine, which may lead to increased wear on mechanical parts.
I run an auto repair shop and have seen many new cars develop problems due to improper driving during the break-in period. The first 1000 kilometers are the most critical—keep the RPM below 3000. For manual transmissions, driving at 70-80 km/h in 5th gear is the smoothest. For automatics, it’s simpler: avoid stomping on the accelerator and maintain a steady speed between 60-100 km/h. The key is consistent speed. Avoid prolonged driving at a single speed; on highways, vary your speed occasionally to ensure all gears wear in evenly. After a cold start, let the engine warm up for 30 seconds before driving. For the first 500 km, avoid full-load uphill driving. Tires also need breaking in—take corners slowly in wet conditions for safety.
