What is the speed range for 2nd gear in a manual transmission?

Second gear is typically used between 20 km/h and 35 km/h. Below is a related introduction to the gears of a manual transmission car: 1. 1st gear: Used for normal starting or climbing very steep slopes. The speed is generally around 10 km/h when using this gear; 2. 2nd gear: A transitional gear for acceleration after starting, or used for low-speed driving or climbing steep slopes, with speeds generally around 20 km/h; 3. 3rd gear: Generally used at speeds between 20 km/h and 40 km/h, commonly used for city driving; 4. 4th gear: Can be used at speeds between 40 km/h and 60 km/h; 5. 5th gear: Used at speeds above 60 km/h, typically for high-speed driving.
I've been driving manual transmission for over ten years. The speed range for 2nd gear actually depends on your car model and engine. For regular compact cars, it's usually most comfortable between 20-40 km/h. For example, with a 1.5L engine, going below 15 km/h will cause lugging, while exceeding 45 km/h makes the engine roar. SUVs with greater torque might handle 15-50 km/h in 2nd gear. Don't just rely on the speedometer when shifting - listen to the engine sound, and upshift to 3rd gear when RPM reaches around 2500. Using 2nd gear at low speeds provides excellent stability when cornering on wet roads, and it helps with engine braking when descending steep slopes. Remember each car has its own characteristics - with enough practice, you'll naturally learn its optimal range.
There's no fixed speed for 2nd gear in manual transmission - it depends on the car's performance. For my small-displacement car, 20-35 km/h in 2nd gear works well, with the smoothest operation between 2000 to 3000 RPM. On uphill sections, downshifting to 2nd gear and revving to 3500 RPM can power through. The key is avoiding too low or high RPM: below 1500 RPM causes shaking, while exceeding 4000 RPM wastes fuel. You'll need to experiment with different cars to find the sweet spot - being off by 3-5 km/h isn't critical. When maneuvering in residential areas, I often use 2nd gear at around 15 km/h, which feels much smoother than 1st gear.
