Is It Normal to Run at 3000 RPM for 120 km/h?

[SanGabrielle]

Running at 3000 RPM for 120 km/h is normal, but this also depends on the vehicle's displacement, whether it's a manual or automatic transmission, and should be judged comprehensively based on these factors. Calculation of car engine RPM: Wheel RPM equals the vehicle speed divided by the tire circumference. The tire's RPM is related to many factors, such as the gear ratio, tire diameter, etc. Different types of tires will produce different RPMs. When the wheel RPM is constant, the wheel diameter is directly proportional to the distance traveled. Differences in car engine RPM: At the same speed, RPM can vary. The fundamental reason is the transmission ratio. A larger transmission ratio means the engine has to rotate many times for the wheel to rotate once, while a smaller transmission ratio means the engine rotates once for the wheel to rotate several times.
