Is driving a new car at 160 km/h harmful?

Generally, driving a new car at 160 km/h won't cause significant damage, but it's recommended to avoid sudden acceleration before the first maintenance. After the first maintenance, you may consider doing a high-speed run. The break-in period for a new car typically ranges from 1,000 to 3,000 kilometers, during which it's advisable not to drive too fast—keeping the speed between 50-90 km/h is ideal. Warm up before starting: After starting the engine, you can begin driving as long as it maintains a stable idle. Before the engine reaches normal operating temperature, moderate your speed. Once the engine is warmed up, you can drive normally. During the break-in period, avoid hard acceleration and sudden braking. Avoid high-speed driving: New cars have speed limits during the initial driving phase. For domestic cars, the limit is usually between 40-70 km/h; for imported cars, it's generally within the first 1,000 kilometers, with the speed not exceeding 80% of the maximum speed at full throttle. It's also important to monitor the engine RPM and speed gauges to ensure both are operating within moderate ranges.

Driving a new car at 160 km/h is honestly quite hazardous. As an average car owner, I must point out that high-speed driving exacerbates break-in period issues—engine components aren't fully lubricated yet, and high RPMs may increase friction causing internal damage. Tire wear accelerates too, braking distance extends, and if sudden situations occur ahead, reaction time becomes insufficient. New car manuals often recommend keeping speed below 100km/h before first maintenance to avoid excessive RPM. I've seen friends aggressively drive new cars at high speeds, resulting in louder engine noise and voided warranty coverage. Safety-wise, 160km/h poses extreme risks on regular roads, with significantly increased accident and fatality rates. New owners should gradually adapt, increasing speed progressively to protect both their vehicle and themselves.

Having driven for over a decade, my experience tells me that pushing a new car to 160 km/h is not a good idea. The engine and suspension of a new car haven't been properly broken in yet, and high-speed operation can easily lead to uneven wear of components, shortening their lifespan. I once tried taking a new car on a long-distance high-speed trip within the first week of purchase, and afterwards, the fuel consumption skyrocketed, with frequent visits to the repair shop. The mechanic said that excessive initial speed could damage internal seals and affect performance. Now, I always follow the manufacturer's guidelines: keep the car at low RPMs for the first 2,000 kilometers. This not only extends the vehicle's lifespan but also saves on repair costs and time. Driving isn't about who's faster; it's about reaching the destination safely. Treating a new car with care is like taking care of yourself—start slowly and let it grow healthily.

New engine designs require a break-in period, and high-speed driving such as 160 km/h can impose unnecessary stress. From a mechanical perspective, high RPMs increase friction and heat between metal components, which can easily scratch pistons and cylinders, shortening their lifespan. During the break-in period, it is generally recommended to maintain moderate speeds to allow parts to naturally adapt. Excessive speed also accelerates tire wear, necessitating frequent checks for balanced tire pressure. Fuel consumption also spikes significantly—160 km/h consumes nearly twice as much fuel as 100 km/h. In short, from a mechanical standpoint, it's not advisable. A new car should be treated gently.
