What is the RPM of a manual Civic at 120 km/h?

The RPM of a manual Civic at 120 km/h is around 2000. Car RPM: The RPM of a car has a significant relationship with its fuel consumption per 100 kilometers. The fuel consumption displayed on the dashboard is calculated based on a specific method. The car's computer monitors the fuel injected by the engine's injectors, records the instantaneous fuel consumption at every moment, and then calculates the total fuel consumption and distance traveled. By dividing the total fuel consumption in liters by the distance in kilometers, the fuel consumption per 100 kilometers is obtained. Fuel consumption per 100 kilometers for sedans: Generally, the fuel consumption per 100 kilometers for family sedans is around 6L to 8L, while for SUVs, it is around 8L to 10L. However, the fuel consumption per 100 kilometers always has some margin of error. If the engine operates at high RPM for a long time or accelerates frequently in the low RPM range, the fuel consumption per 100 kilometers will increase.
I've been driving a manual Civic for several years, often cruising at 120 km/h on highways with RPM around 2500 to 2700, depending on which gear you're using. Generally, 6th gear is the most comfortable, keeping the RPM lower for a quieter and more fuel-efficient ride. I remember driving a newer Civic model once, where the RPM stayed around 2500, and the engine ran so smoothly with almost no noise—much better than the older models I used to drive. The older versions had fewer gears, and if you used 5th gear, the RPM could climb to 2800 or even 3000, increasing fuel consumption. I recommend using 6th gear for cruising whenever possible—it reduces engine load and can even extend engine life. On long trips, keep an eye on the RPM and avoid letting it drop too low or climb too high; maintaining it around 2500 is ideal.
