What is the ideal RPM at 120 km/h?
1 Answers
At a speed of 120 km/h, an engine RPM of around 2200 is considered ideal, which is typical for high-performance vehicles. The general RPM range for regular vehicles and the relationship between RPM and engine performance are as follows: General RPM range for vehicles: Under a speed of 120 km/h, most sedans maintain an engine RPM between 2300 and 2600. For SUVs or off-road vehicles, due to their higher profile and greater wind resistance, the engine RPM tends to be around 3000. Relationship between RPM and engine performance: A lower RPM indicates a better engine. This is because a lower RPM at high speeds means the engine can deliver more power per revolution compared to others, thus providing sufficient power for high-speed driving while maintaining significantly lower RPM.
