What is the RPM of the Geely Xingrui at 120 km/h?

Geely Xingrui's RPM at 120 km/h is 2000-2200. Introduction to RPM: Rotational Speed (or Rev) refers to the number of revolutions an object moving in a circular path makes around the center of the circle per unit time (different from frequency). Common types of rotational speed include rated speed and maximum speed. Rated Speed: Rated speed refers to the maximum rotational speed under rated power conditions. It is usually marked on the prominent part of the product as a main parameter when leaving the factory. Maximum Speed: Maximum speed is the highest rotational speed that can be achieved under specific conditions. For example, the spindle speed of a hard disk drive motor, which is the maximum speed the hard disk platter can reach under normal operating voltage conditions.
When I drive the Geely Xingrui on the highway at 120 km/h, the RPM generally ranges between 2300 and 2600, depending on the specific model configuration. For example, the one I tested with a 2.0T engine and a 7-speed dual-clutch transmission maintains a stable RPM of around 2500. I think this range is quite reasonable, as the engine can deliver sufficient power even at lower speeds, which helps with fuel efficiency. Additionally, gear ratio design is crucial—maintaining low RPM in higher gears during highway driving reduces cabin noise and enhances comfort. If the engine frequently operates at high RPM, checking for a clogged air filter or extended maintenance intervals can prevent excessive engine load. In short, monitoring dashboard changes while driving ensures everything is functioning properly.
As a driver who frequently takes long-distance trips, when I drive the Geely Xingrui at speeds of 120 km/h, the tachometer reading usually fluctuates around 2400 rpm. The automatic transmission in this car makes gear shifts very smooth, and the RPM control is excellent—much quieter than older models. If the RPM is too low, the car feels floaty; if it's too high, it consumes more fuel. I believe the safe range is between 2300 and 2700 rpm. Additionally, when the weather is hot, the engine bears less load, and the RPM tends to be slightly lower, but it generally stays within the normal range. It's important to regularly change the engine oil and transmission fluid to maintain smooth engine operation. After prolonged high-speed driving, step out of the car and listen to the engine sound to check for any abnormal humming noises—experienced drivers can easily detect unstable RPM issues.
At 120 km/h, the engine speed is approximately 2200 to 2800 rpm, depending on the Xingrui's different engines. For example, the 1.5T model may reach 2600 rpm, while the 2.0T is slightly lower at 2400 rpm. The gear has a significant impact, with manual transmissions running higher and automatic transmissions reducing the speed. I recommend paying attention to the instrument panel during daily driving.
