What speed should the engine run at 2000 RPM?

When the engine is at 2000 RPM, the vehicle speed can generally reach around 80 km/h. Of course, the engine speed and vehicle speed are not in a one-to-one correspondence, as it also depends on the current gear, which is the transmission ratio. For new cars, the engine speed should not exceed 3000 RPM: Both excessively low and high RPMs are detrimental to engine break-in. The break-in period is divided into the initial, middle, and final stages, which is the process of forming an oxide protective film on internal engine components. Therefore, the quality of the break-in period directly affects the engine's lifespan in the long run. Generally, the first 500 km is the initial break-in period: It is advisable to keep the speed below 80 km/h and the RPM below 2200. The tire break-in period is 300 km, and since new tires lack optimal friction, driving should be cautious during this time.
To be honest, based on my years of driving experience, the speed corresponding to 2000 RPM is definitely not a fixed number—it entirely depends on your car and gear. For example, when I drive a manual transmission SUV, if I'm cruising in fifth gear on the highway, 2000 RPM might correspond to around 80 km/h; but if I'm stuck in city traffic in second gear, I'd be lucky to hit 30 km/h. Automatic transmission cars are even more flexible—the computer adjusts gears automatically based on throttle input and road conditions, leading to greater speed variations. The key is not to rely solely on RPM to judge speed; always check the actual speed displayed on the dashboard to avoid speeding or unsafe driving. Factors like vehicle type, gear ratios, and tire size all affect the outcome, so I recommend observing how your own car performs at 2000 RPM in different gears during normal driving.
