What speed can a new car reach on the highway after 1000 kilometers?

[VanNora]

After running 1000 kilometers, a new car can maintain a speed of 100-120 km/h on the highway, just make sure the engine speed does not exceed 3000 rpm. Precautions during the break-in period: During the break-in period, avoid putting excessive load on the engine, do not drive for excessively long periods, especially avoid prolonged high-speed driving. Operate each gear smoothly, avoid sudden acceleration, and be gentle when starting or going uphill to prevent overly aggressive driving. Recommended speed and engine rpm for different break-in stages of a new car: For the first 500 kilometers (early break-in stage), maintain a speed of 60-70 km/h with engine speed not exceeding 2200 rpm. From 500 to 1000 kilometers (mid break-in stage), keep speed between 90-100 km/h with engine speed below 2500 rpm. From 1000 to 1500 kilometers (late break-in stage), the speed can be increased up to 120 km/h as long as the engine speed stays below 3000 rpm.
