What is the optimal engine RPM for shifting gears?

[DelAlex]

Shifting gears is generally recommended between 1500-2500 RPM. Below are key points about gear shifting: 1. If you want better power performance, you can shift gears around 2000-2500 RPM. 2. The relationship between vehicle speed and RPM is not one-to-one; it mainly depends on the transmission gear ratio. For instance, in a speed-RPM gear comparison chart, when the engine is at 2000 RPM, there's a significant difference between 4th and 5th gear speeds. Most vehicles typically shift appropriately between 2000-3000 RPM, but shifting from 1st to 2nd gear is often lower, around 2000 RPM or slightly above. 3. Some low-RPM engines can deliver substantial torque and power at lower RPMs, allowing gear shifts around 2000 RPM or even 1500 to 1800 RPM. Generally, non-turbocharged engines achieve over 80% torque output only above 2500 RPM, so maintaining power requires shifting between 2500-3000 RPM, though this consumes more fuel. 4. For turbocharged engines, torque output reaches over 90% at around 2000 RPM, allowing gear shifts at this point. The ideal RPM for shifting largely depends on driving experience.
