What is the maximum speed achievable in first gear?

When the throttle is fully depressed in first gear at 8000 RPM, the speed can reach 50 km/h, and at 12000 RPM, it can reach 70-80 km/h. Below is relevant information about first gear speeds: 1. Speed ranges for each gear: In first gear, fully depressing the throttle at 8000 RPM can achieve 50 km/h, and at 12000 RPM, it can reach 70-80 km/h. For second gear, the corresponding speed range is 15-80 km/h; third gear corresponds to 0-120 km/h; fourth gear to 25-160 km/h; and fifth gear to 30-200 km/h. 2. Notes on gear shifting: When shifting gears while driving, it's important to note that higher gears have lower torque, and accelerating in them may actually slow the car down. First gear should be used when starting the car, and after starting, you can shift to second gear, gradually shifting up based on speed. Looking down at the gear lever during shifting can easily lead to rear-end collisions and other traffic accidents.
When driving, I often test the performance of different car models. First gear can generally reach speeds between approximately 15 to 40 kilometers per hour, depending on the vehicle size and engine horsepower. For example, small sedans may max out around 20 km/h, while large SUVs might exceed 35 km/h. Since first gear is primarily designed for starting and climbing steep slopes, its gear ratio is set very low—resulting in high RPMs but slow speeds. Frequently revving the engine in first gear can wear out both the engine and transmission, potentially leading to overheating issues over time. That’s why I always shift to second gear or higher as soon as possible in real-world driving, which saves fuel and enhances safety. Using first gear briefly in city traffic jams is fine, but it’s definitely not advisable on highways. Car knowledge like this is quite fascinating, and understanding these details can help extend a vehicle’s lifespan.
As someone who has worked on cars for many years, I've seen all kinds of situations. The top speed in first gear is generally in the range of 20 to 30 kilometers per hour, depending on engine RPM and gear ratio settings. For example, a regular family car might reach 25 km/h at 5000 RPM, but don't force it higher, as this could easily damage the clutch or drive shaft. The key point is to regularly check the vehicle's maintenance status - lack of engine oil or low battery voltage can affect speed performance. If owners notice first gear being unusually fast or slow, I recommend checking throttle response and wiring issues. Safety first - focusing on proper shift timing while driving can prevent accidents.
When I first started learning to drive, I was also curious about first gear speed. My instructor told me it can only reach about 10-25 km/h at most. Why so slow? Because first gear is designed for smooth starting - the engine revs high but the car barely moves. Try pressing the accelerator to feel it yourself. There are noticeable differences between new and old cars, as well as between manual and automatic transmissions. In actual driving, I quickly shifted to higher gears to save fuel and protect the car. This reminds me that as a beginner, I should focus more on practice rather than obsessing over low gears, because safe driving is what matters most.
