What is the appropriate speed for a new car?

During the break-in period of a new car, the speed should not be too high, generally controlled between 50-90km/h. Here are other precautions regarding new car driving: 1. Avoid driving with a full load: Excessive load will increase the burden on the engine and transmission, causing the engine to output excessive power and leading to excessive wear of components. Therefore, avoid driving with a full load during the break-in period to extend the service life. 2. Avoid prolonged driving in low gears: For automatic transmission models, although the manual gear shifting process is eliminated, under good road conditions, the owner should continuously accelerate to allow the transmission to smoothly shift up, avoiding the lack of a break-in process for high gears.

When I first got my new car, I also struggled with this issue. The experienced mechanic at the 4S store told me that new cars need a break-in period, and the first 1,000 kilometers are particularly critical. The engine and transmission parts haven't fully meshed yet, so don't drive too fast—keep it around 60 km/h in the city and under 100 km/h on the highway. Even after the break-in period, don't go too wild; the most fuel-efficient speed is usually around 80 km/h. Remember not to constantly redline the engine, especially with an automatic transmission. Driving gently not only protects the engine but also saves on maintenance costs. Now, after three years, my car still has great power. Developing good habits during the novice period is very important.

The appropriate speed for a new car depends on road conditions. During urban rush hours, it's safest to follow the traffic flow at 40-60 km/h. On highways, maintaining around 110 km/h is most economical, as both new tires and brakes need time to adapt. Once I drove too fast in a hurry and noticed the ABS intervened aggressively during emergency braking. A technician later informed me that new brake pads require a 300-km break-in period. It's good practice to test steering feedback at various speeds, especially when taking low-speed turns in rainy conditions - immediately reduce speed if you feel insufficient grip, as safety always outweighs speed.

For a new car during the break-in period, it's recommended not to exceed 80 km/h, with the engine RPM ideally maintained below 2,500. The transmission requires an adaptation period of approximately 300 kilometers, and frequent rapid acceleration can damage the clutch plates. For highway driving, cruising at 100 km/h provides stability, with reduced wind noise and better fuel efficiency. I prefer using cruise control to maintain speed, which helps avoid speeding fines. Remember to check tire pressure monthly, as insufficient pressure increases fuel consumption and isn't good for the new car's suspension.

Don't rush to speed in a new car, especially the first 500 kilometers are the golden break-in period. During my daily commute on the expressway, I keep it under 70 km/h to avoid traffic congestion and allow the engine to break in smoothly. On long trips, take a break at service areas every two hours to let the turbocharger cool down. The first oil change should be done around 1,000 kilometers to remove metal debris. When using the air conditioning, avoid sudden acceleration as the new compressor is more sensitive; maintaining a steady speed best protects the components. Regularly check the dashboard data—a sudden increase in fuel consumption is a sign you're driving too fast.
