What is the appropriate speed for running-in a new car?

Running-in a new car after 2500 kilometers involves increasing the maximum speed by 10 kilometers every 500 kilometers. It is important to reasonably control the driving speed during the running-in period. Below are detailed explanations about vehicle speed: Overview: Vehicle speed refers to the distance a car travels per unit of time, commonly measured in kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Others: Vehicle speed can also generally refer to the speed of motor vehicles. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and ensure their coordination.
When it comes to the appropriate speed for highway driving, as a seasoned driver with years of experience, I believe safety should be the top priority. On highways, where the speed limit is mostly between 100 to 120 kilometers per hour, I usually maintain a speed of around 100 km/h. This helps avoid speeding while ensuring I can react promptly to unexpected situations. In poor road conditions or heavy traffic, I prefer driving between 90 to 110 km/h to maintain a safe distance. Excessive speed not only increases fuel consumption but also raises the risk of losing control, especially during rain or snow when reducing speed is essential. Additionally, vehicle condition is crucial. Regular checks on tires and brakes are necessary. If a new car has just passed its break-in period, maintaining a steady speed of 100 km/h for about half an hour can help clear carbon deposits. Comfortable driving not only protects yourself but also considers other drivers. Never overlook dangers just for the sake of speed.
I believe the optimal speed range for highway driving is between 90 to 110 km/h. When I first bought my car, the technician mentioned this speed range offers the best balance: too slow wastes fuel and delays the journey, while too fast increases fuel consumption and engine strain. The vehicle manual recommends maintaining around 100 km/h as the most economical speed for optimizing fuel efficiency. I often check the fuel gauge during highway driving, and consumption is lowest at this speed, with the engine running smoothly. In terms of comfort, cabin noise is minimal, and family members don't experience motion sickness. For safety, never exceed posted speed limits, especially slowing down before curves or tunnel entries. Remember in daily driving that speed and stopping distance are directly proportional - reducing speed slightly in heavy highway traffic is wiser.
