Can a new car run at 120 km/h on the highway?
2 Answers
New cars should not run at 120 km/h on the highway. Although new cars have undergone run-in after leaving the factory, the surfaces of the parts are still relatively rough. During the break-in period, it is essential to control the driving speed and avoid excessively high speeds. The speed should be maintained between 50 to 80 km/h. After driving 1,500 kilometers, the engine speed and vehicle speed can gradually be increased to the maximum allowed by the vehicle. Avoid pressing the accelerator pedal too hard in a new car to ensure that the pistons, cylinders, and other critical components increase their load under moderate conditions. This allows the parts to fully contact, rub, adapt, and settle, improving the ability of various components to adjust to the environment and smoothing out any protrusions on the parts. The quality of the break-in process will significantly impact the car's lifespan, safety, and fuel efficiency.
I just bought a new car last month and couldn't wait to test it on the highway at 120 km/h. It performed quite impressively, running smoothly without any feeling of instability. Since the new engine is still in the break-in period, the manual recommends keeping the speed below 100 km/h for the first 1,000 kilometers to avoid putting too much stress on the engine. I drove at 120 km/h for a long stretch, and after checking, the engine oil and tire conditions were fine, with fuel consumption averaging around 7 liters per 100 km. However, it's important to remind everyone to maintain a safe distance and be mindful of weather conditions on the highway, as the braking system of a new car might not be fully broken in yet. Regularly checking tire pressure and sticking to the maintenance schedule is also crucial—don't risk damaging your new car just for speed.
