What are the corresponding speeds for the 5 gears?

1st gear: 10-40KM; 2nd gear: 15-80KM; 3rd gear: 0-120KM; 4th gear: 25-160KM; 5th gear: 30-200KM. Below is relevant information about gears: Concept: Gears are adjustment devices that regulate a car's speed and traction (torque). The lower the gear, the slower the speed, but the greater the car's traction (torque). The higher the gear, the faster the speed, but the smaller the car's traction (torque). Gears are generally divided into two main categories: forward gears and reverse gears. Engaging a forward gear makes the car move forward; engaging reverse makes the car move backward. Ordinary car gears: Typically, ordinary cars have five forward gears and only one reverse gear. The first forward gear is the starting gear, where the speed is the slowest (0-10 km/h), but the torque is the greatest. Application of each gear: 1st gear is also suitable for climbing steep slopes. After starting, when the engine speed reaches around 2000, shift to 2nd gear, which is suitable for low-speed urban driving and climbing gentle slopes. Similarly, shift to the next gear when the speed reaches around 2000. The 4th and 5th forward gears are high-speed gears, suitable for driving on highways with good road conditions.

I've been driving manual for ten years, and here's my usual approach: shift to second gear immediately after starting in first (10-20km/h), second gear is most commonly used for city driving (20-40km/h). Third gear is the smoothest for overtaking at 40-60km/h, with the RPM just around 2500. Fourth gear is fuel-efficient for 60-80km/h, and on the highway, I shift to fifth gear for cruising once I hit 80km/h. However, gear ratios vary by car. When driving a small-displacement car, the engine would scream if I pushed third gear to 70km/h, but in my friend's 2.0T car, third gear could easily reach 90km/h. The key is to keep an eye on the tachometer and not exceed 3000 RPM, which protects the engine and saves fuel.

I still use the gear-shifting mantra taught by my driving instructor: first gear for starting under 20 km/h, second gear for smooth driving between 20-40 km/h, third gear for sufficient power between 40-60 km/h, fourth gear for fuel efficiency above 60 km/h, and fifth gear for highway cruising starting at 80 km/h. However, in practice, I found big differences between new and old cars. My old Jetta would vibrate intensely when reaching 70 km/h in fourth gear, forcing me to shift to fifth. Yet when driving my cousin’s turbocharged car, second gear could even pull up to 80 km/h! So don’t just rely on the speedometer—listen to the engine sound to judge the right timing.
