What is the recommended speed for a new car on the highway?
3 Answers
Detailed introduction for running a new car on the highway is as follows: 1. Maintain a reasonable speed: Avoid driving at low speeds or accelerating rapidly with high RPM. It is best to keep the speed within 100km/h, and pay attention to the engine RPM and speedometer during driving. The engine RPM should preferably not exceed 3000. 2. Avoid flooring the accelerator when starting or slamming on the brakes: Emergency braking will impact the braking system and increase the load on the chassis and engine. 3. For manual transmission models, use the gears appropriately and avoid driving in low gear for extended periods: Neither high gear at low speed nor low gear at high speed is the best option. 4. Do not drive with a full load or overload, as this can damage the new car's components: If the new car is used in winter in the north, allow sufficient time for the engine to lubricate before starting, and briefly warm up the vehicle.
I've got experience with taking a new car on the highway - best not to floor the accelerator right away. The engine is still in its break-in period, so maintaining around 100 km/h is advisable. Pushing too hard can easily rev the engine past 3,000 RPM, which isn't ideal for gear break-in. My approach is keeping it between 90-100 km/h for the first 500 km, then gradually increasing to 110 km/h for the next 500 km. Weather conditions matter too - rainy days call for reducing speed to 80 km/h for safety. On highways, don't just focus on speed limits; maintain at least 150 meters following distance. New brake pads also need breaking in - emergency stopping distances are about 20% longer than normal. Keep an eye on the coolant temperature gauge too, as long drives put extra stress on the cooling system. Safety first - no need to rush.
When driving a new car on the highway, focus on two key aspects: legal speed limits and vehicle condition. In China, the highway speed limit is generally 120 km/h, but it's advisable not to push a new car to its maximum limit right away. Back in driving school, I learned that during the break-in period (first 2,000 km), it's best to keep engine RPM below 2,500. For a 1.5L engine, 100 km/h corresponds to about 2,600 RPM, so maintaining 90-110 km/h is ideal. Road conditions matter too – I usually reduce speed to 80 km/h in heavy truck traffic to minimize wind pressure. Night driving requires extra caution; novice drivers should use cruise control set at 100 km/h for stability. Always check tire temperature during rest stops – overheating indicates excessive speed.
