What is the speed corresponding to C1 gear?

Gear and speed correspondence: 1st gear - starting; 2nd gear - 20 km/h; 3rd gear - 30 km/h; 4th gear - 40 km/h; 5th gear - 60 km/h. Here is some additional information: 1. Gear shifting: Gear shifting is generally based on RPM. It is recommended to develop the habit of shifting gears based on RPM, shifting between 2000-2500 RPM. 2. Manual transmission: A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the drive wheels. It enables the vehicle to achieve different traction forces and speeds under various conditions such as starting from a standstill, climbing hills, turning corners, and accelerating, while also allowing the engine to operate within a more favorable RPM range.

When I first started learning to drive, I was also particularly curious about the speed in C1 gear, but honestly, it's not fixed at all—it entirely depends on what type of car you have. For example, my first car was a small city car, and first gear could push it to around 15 km/h, but if you're driving an SUV or a pickup truck, first gear might only get you to about 10 km/h at the start, feeling much more sluggish. Engine size, vehicle weight, and road conditions all affect the speed—it’s even slower on steep slopes or when fully loaded. I recommend checking the vehicle manual, which usually provides a recommended speed range, like around 10 to 20 km/h for starting in an economy car. Don’t worry about shifting mistakes; it’s common for beginners. With more practice, you’ll learn to upshift when the engine sound gets louder or the RPM exceeds 2500, making the drive smoother.

Having driven for over a decade, I've noticed significant speed variations in the C1 gear, which relate to vehicle design and actual driving conditions. In my experience, compact cars can reach up to 18 km/h in first gear, while mid-sized vehicles might only achieve around 12 km/h. Key factors include engine power—a 1.5L engine differs from a 2.0L in speed limits—and road gradient matters too; flat roads allow higher speeds, but uphill often drops to 8 km/h. Load also plays a big role—when fully loaded, cautious deceleration is necessary. I often advise friends not to rigidly memorize numbers but to rely on feeling engine vibrations or listening to sounds—shifting gears at around 2,000 RPM is safest. Always leave some margin while driving to avoid stalling or jerking.

From a technical perspective, there is no standard speed value for C1 gear, as it is determined by the transmission gear ratio and engine RPM. Simply put, a higher gear ratio means slower wheel rotation per engine revolution. For small-displacement vehicles, first gear may propel up to 15 km/h, while larger vehicles may be slightly slower. Through testing various models, I've found that starting at idle with engine RPM around 2000 achieves optimal speed, but exceeding 3000 RPM produces harsh noise. Other influencing factors include tire size and terrain - speed may halve when climbing or off-roading. I recommend using the tachometer as reference, maintaining within the green zone for optimal fuel efficiency. Remember, C1 gear is primarily for starting or low-speed maneuvers - never force it back at high speeds to protect the transmission.
