What is the appropriate speed at 2000 RPM?

[StCaleb]

When the engine is at 2000 RPM, the speed can generally reach around 80 km/h, which is normal. Higher speed leads to higher RPM, but higher RPM does not necessarily mean higher speed. If the gear is in neutral, the speed will be zero, and even with heavy throttle in low gear, the speed will not increase significantly. Below is some relevant information about engine RPM: The relationship between engine RPM and vehicle speed: A higher engine RPM does not always mean a higher vehicle speed. For example, at 2000 RPM, if the transmission is in first gear, the speed may be around 15 km/h; in second gear, it could be 25 km/h; in third gear, around 40 km/h; and in fifth gear, approximately 80 km/h. Precautions for new car RPM: For a new car, the RPM should not exceed 3000. Both excessively low and high RPM are detrimental to engine break-in. The break-in period consists of initial, intermediate, and final stages, during which an oxide protective film gradually forms on the internal engine components. Therefore, the quality of the break-in period directly affects the engine's lifespan in the long run.
