What is the speed range for first, second, and third gears?

First gear is the starting speed, typically ranging from 0-5 km/h. Second gear corresponds to a speed range of 5-20 km/h. Third gear corresponds to a speed range of 20-40 km/h. Additional information is as follows: 1. Timing for upshifting: When the engine has sufficient power, it emits a dull "humming" sound. If after upshifting there is no power deficiency or shaking of the transmission mechanism, and the vehicle speed increases rapidly with smooth and natural driving, it indicates accurate timing for upshifting. 2. Timing for downshifting: When the vehicle speed and engine RPM continue to drop, and you feel the car losing power with engine compartment vibration, it's time to downshift one gear. Downshifting too early will cause noticeable jerking, wasting engine power, increasing fuel consumption, and affecting the lifespan of the engine and transmission. Downshifting too late will result in continued power deficiency even after downshifting, and further downshifting will still feel jerky. Misjudging the shifting timing can lead to such "irreversible" consequences, which will inevitably affect the driving experience.
When I first started learning to drive, I often pondered the relationship between gears and speed. First gear is ideal for the initial acceleration phase, best suited for speeds between 0 to 20 km/h. Going too fast in first gear can strain the engine, but it works well for climbing hills or starting at traffic lights. Second gear is perfect for city driving at 20 to 40 km/h, like moving steadily in traffic jams—it feels like the car has ample power without much effort. Third gear covers the 30 to 60 km/h range, great for cruising on suburban roads or flat terrain, with gear shifts around 2000 RPM for better fuel efficiency. This can vary by car, though. I’ve driven different vehicles and noticed SUVs can hit 60 km/h in third gear at lower RPMs, while smaller cars might need higher revs. Paying attention to the tachometer and how the car responds helps build a habit for safer, more efficient driving. On slippery roads or inclines, gear selection requires extra caution to avoid accidents. With more practice, you’ll naturally get the hang of it.
Shifting gears is something I must say every car has its own rhythm. First gear works best at around 0-20 km/h, mainly used for initial acceleration or climbing steep slopes. When shifting to second gear at 20-40 km/h, the engine torque is stronger, helping avoid frequent braking in city traffic. Third gear enters the 30-60 km/h range, serving as the preparation stage for higher speeds, and can significantly reduce fuel consumption under smooth driving conditions. There are many influencing factors, such as diesel engines being more powerful at low speeds, allowing slightly earlier shifts to third gear up to 60 km/h, while gasoline cars require slightly higher RPMs. I recommend adjusting flexibly based on road conditions—shift earlier on dirt roads or in rainy weather to prevent skidding; observe vehicle vibrations during daily driving, as noticeable shaking indicates an inappropriate gear. Remember, smooth acceleration protects the engine, and with more experience, you'll naturally find the matching point. During weekend road trips, when encountering slopes, maintaining around 30 km/h in second gear is a safe approach.
