What Speed Matches Which Gear?

Manual transmission gear speeds are as follows: 1st gear: generally around 10km/h; 2nd gear: generally around 20km/h; 3rd gear: typically used between 20 to 40 km/h; 4th gear: between 40-60km/h; 5th gear: above 60 km/h. Below is an introduction about gears: Upshifting: Regardless of the current gear, when the engine reaches 2500 RPM, shift up one gear. The gears in the transmission are arranged by size. Gear and gear position matching: The larger the gear, the slower the rotation speed, corresponding to a lower gear position and slower vehicle speed; The smaller the gear, the faster the rotation speed, corresponding to a higher gear position and faster vehicle speed.
The matching of speed and gear is not fixed; it relies more on feel and experience. Having driven for over a decade, I generally follow this principle: use first gear from start to 15 km/h, then shift to second gear up to around 30 km/h, keep third gear between 30-50 km/h, fourth gear between 50-70 km/h, and fifth gear for speeds above 70 km/h on highways. Different car models and situations vary—small-displacement cars benefit from early upshifts for fuel efficiency, while larger vehicles climbing hills should delay upshifts for power. Keep an eye on the tachometer; maintaining around 2,000 RPM is usually the smoothest—too high causes noise and wastes fuel, too low makes the car shudder. In city traffic, second and third gears are common, while fifth or sixth gear is ideal for highway cruising. A few practice runs will make it intuitive—the key is listening to the engine’s smooth sound, avoiding excessive roaring or struggling.
Matching speed and gear is key to safety and fuel efficiency. For speeds below 20 km/h, it's recommended to stay within second gear for safe starts and to avoid stalling. Between 30-60 km/h, use third or fourth gear for smooth driving, avoiding sudden acceleration that could harm the engine. At speeds above 70 km/h, shift to fifth gear for cruising to save fuel. Pay attention to the RPM, aiming to shift gears within the 1800-2500 RPM range to protect the transmission's lifespan. Different road conditions have a significant impact: when going downhill, downshift early to use engine braking; when going uphill, delay upshifting to prevent lugging. Beginners should remember that if the car starts shaking or smoking, it's a signal of gear mismatch—pull over and adjust. Developing this habit leads to smoother driving, reduces the risk of accidents, and saves a considerable amount on fuel costs.
