How many kilometers can a car travel per hour?

A car's travel distance per hour depends on its actual speed. Generally, the average speed of a small car is around 60 km/h. Here's an introduction to the travel conditions of cars with different displacements: 1.6L displacement: A car with a 1.6L displacement can reach a maximum speed of 180 km/h, meaning it can travel up to 180 kilometers in one hour under ideal conditions. 2.4L displacement: For a car with a 2.4L displacement, the maximum speed can reach 200 km/h, so it can travel up to 200 kilometers in one hour, again under unrestricted conditions.

I've been driving all my life, and car speed can't simply be fixed at one number. Typically, in the city, it's around 30 to 60 kilometers per hour because there are many traffic lights and pedestrians, so you have to go slower. On the highway, you can go up to 100 or 120, but you have to watch the speed limit signs to avoid speeding—speeding tickets are expensive. Different car models make a big difference; my old sedan feels more unstable on the highway compared to my friend's SUV. In rain or snow, I slow down to below 50 for safety, and even slower in poor road conditions. I remember once driving at 110 on the highway when a truck suddenly cut into my lane—luckily, I didn't accelerate, so I avoided a collision. Overall, speeds between 50 and 120 kilometers per hour are normal, but you have to adapt flexibly to road and vehicle conditions.

As someone who frequently deals with car maintenance, speed fluctuations between 50 and 140 km/h are quite common. High-performance sports cars with powerful engines can accelerate quickly, while regular family sedans are most fuel-efficient at speeds of 80 to 90 km/h. Vehicle weight and road gradients affect acceleration—speed may drop by half when climbing hills. Insufficient tire pressure can also slow you down; I once helped a neighbor adjust their tire pressure, and their speed stabilized noticeably. Electronic speed limiters control speed to prevent exceeding limits, and it's advisable to maintain around 100 km/h on highways. Weather conditions like strong winds can destabilize the car at high speeds, requiring you to slow down. Car manuals usually indicate the most economical speed—refer to that for optimal performance.

I just got my driver's license a few months ago, and my driving instructor told me that speed isn't fixed. Normally, I drive between 30 to 50 km/h in the city, and even slower near schools. On the highway, I've tried 90 km/h and felt quite stable, but seeing others at 120 km/h is scary and I don't dare to follow. For beginners, it's recommended to stay conservative, below 80 km/h, to avoid accidents. Speed varies greatly depending on road conditions; on bumpy roads, 40 km/h is safer. Older cars also require lower speeds; my second-hand car sometimes shakes uncomfortably at 80 km/h. In general, speeds range between 50 to 120 km/h, but safe driving is always the top priority.
