What is the reasonable engine RPM for shifting gears?

[LeEverett]

For most common vehicles, it is appropriate to shift gears at 2000-3000 RPM. The following data indicates suitable RPM ranges for shifting: Starting in first gear: Engine RPM around 1000-1500, vehicle speed at 10 km/h, then shift to second gear. In second gear: Engine RPM around 1500-2000, vehicle speed reaching 30 km/h, then release the throttle and shift to third gear. In third gear: Engine RPM around 1500-2000, vehicle speed reaching 40 km/h, then release the throttle and shift to fourth gear. In fourth gear: Engine RPM around 1500-2000, vehicle speed reaching 50-70 km/h, then release the throttle and shift to fifth gear. In fifth gear: Engine RPM around 1500-3000, vehicle speed reaching 80-120 km/h. If there are additional gears, continue upshifting based on the pattern and actual driving feel.

I've been driving manual transmission cars for over a decade, and shifting RPM is quite an art. Shifting between 2000 to 2500 RPM is ideal, as the engine delivers power smoothly without the shuddering you get at lower RPMs; going too high, like above 3000 RPM, significantly increases fuel consumption. In city traffic jams, I often shift at 2000 RPM for a smooth drive; on highways or uphill, raising it slightly above 2500 is fine. Automatic transmission cars are worry-free, as the system adjusts automatically. However, the car type also matters—smaller engines are better with lower RPMs, while larger engines can handle slightly higher ones. The key is practice and listening to the engine sound. Protecting engine longevity is crucial, and driving this way long-term reduces repairs. Overall, smooth driving benefits both the car and the driver.

I'm a car enthusiast who loves driving manual transmission race cars, and I always shift gears above 3000 RPM! This way, the power bursts are stronger, and overtaking feels exhilarating. Generally, shifting between 2500 and 3500 RPM allows full utilization of the engine's torque curve—for example, my tuned car delivers peak performance at 2800 RPM. On the track or in mountain curves, keeping the revs high ensures quick response; for daily driving, dropping to 2500 RPM is fine if fuel efficiency is the goal. Just remember not to let the coolant temperature get too high, or it could damage the engine. Different speeds require different approaches: shifting at 2500 RPM is stable at 50 km/h, but above 80 km/h, 3000 RPM is necessary. With enough experience, you'll naturally grasp the rhythm.

From an energy-saving perspective, I recommend shifting gears between 1500 and 2000 RPM. The engine operates more efficiently at lower revolutions, reducing fuel consumption and carbon emissions. In urban traffic jams, I shift at 1800 RPM, ensuring smooth operation while being economical and eco-friendly; I maintain this habit on highways too, which reduces long-term fuel consumption. Automatic transmission vehicles handle this automatically, so no need to worry. Be careful not to go below 1500 RPM, as the engine might struggle; going higher wastes resources. A simple adjustment in driving habits benefits the environment.
