What is the normal RPM for a Mazda CX-4 at 120 km/h?
2 Answers
For a Mazda CX-4, the normal RPM at 120 km/h is around 2200 rpm. Solutions for high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, intake system, and engine. Taking the 2021 Mazda CX-4 as an example, its body dimensions are: length 4637mm, width 1855mm, height 1524mm, wheelbase 2700mm, and minimum ground clearance 206mm. The 2021 Mazda CX-4 features a MacPherson strut front suspension and an E-type multi-link rear suspension. It is equipped with a 2.0L naturally aspirated engine, producing a maximum horsepower of 158 PS, maximum torque of 202 Nm, and maximum power of 116 kW. It is paired with a 6-speed automatic transmission.
I just returned from a 2,000-kilometer road trip driving my CX-4 with the 2.0L engine. When cruising at 120 km/h on the highway, I specifically checked the dashboard—the RPM hovered around 2,300. It would climb to 2,500 RPM uphill and might drop slightly above 2,000 RPM downhill. This car uses a 6AT transmission with intelligently tuned gear ratios, keeping the revs low for excellent fuel efficiency. My average consumption was just 6.5L/100km for the entire trip. If you notice someone’s RPM soaring above 3,000, they’re likely in manual mode or the transmission needs servicing. Sustained high-RPM driving not only gets noisy but also risks carbon buildup in the engine—best to visit a 4S shop promptly for a fault code scan.
