The top speed of Haojue Neptune can reach about 100 km/h, but not every car can run that fast. It's normal as long as it can reach a top speed of about 90 per hour.

If you mean how many kilometers you can run, there is no exact standard. Under normal circumstances, if it is used and maintained properly, it is completely possible to drive about 30 thousand kilometers without overhauling the engine. If it breaks down, run as much as you want.
