The maximum speed in first gear is 5km/h. Here are some precautions for gear usage: 1. Gear shifting: Remember the principle of accelerating before upshifting and decelerating before downshifting. Before upshifting, press the accelerator to increase the speed; before downshifting, release the accelerator to reduce the speed. 2. Shifting technique: When shifting gears, try to use the double-clutch method. For upshifting, follow the steps of pressing (clutch), shifting (to neutral), pressing (clutch), and engaging (higher gear). Quickly pressing the clutch pedal twice can make gear shifting easier. 3. Downshifting: Follow the steps of pressing (clutch), shifting (to neutral), releasing (clutch), pressing (accelerator), pressing (clutch), and engaging (lower gear).

I've driven many cars, and the top speed in first gear is usually around 15 km/h. When driving my family car, I need to shift up once the RPM reaches 2000 during startup, otherwise the loud engine sound reminds me not to push it. Occasionally, I can reach 20 km/h when going downhill, but prolonged use causes significant wear to the engine and transmission—like that time I struggled while hauling cargo uphill. Different models vary noticeably: my friend’s heavier SUV is slower in first gear, around 10-12 km/h, while my lighter compact car can hit 15. Ultimately, first gear isn’t designed for high speed; timely shifting protects the car and saves fuel. As an experienced driver, I advise against pushing limits and recommend regular vehicle checks to avoid issues. Remember, safety first—smooth shifting makes for comfortable driving.

As a car enthusiast who loves tinkering with vehicles, I observe the gear ratio and engine RPM most closely in first gear. A standard car typically reaches about 15-20 km/h at 3000 RPM before hitting the redline. If the clutch is worn or the transmission fluid is old, performance may drop to around 10 km/h. I've restored original performance by replacing parts during repairs. Road conditions also matter: speed decreases with heavy loads or uphill driving, while downhill allows slightly higher speeds—though not recommended. Different brands vary; economy cars have gentler first-gear settings, while sports cars may be quicker but risk engine damage. Listening to engine sound helps determine shift points to avoid high-RPM driving and part wear. Routine maintenance like regular oil changes is crucial to prevent failures, and simple checks can significantly extend a car's lifespan.

Having played with performance cars for years, I can accelerate quickly in first gear on the track. My modified car reaches 25-30 km/h at its 5000 rpm limit, with strong instant burst at launch. However, in city driving, it's restricted to under 15 km/h to avoid excessive noise and fuel consumption. Different cars like off-roaders have more durable but slower first gears, while supercars offer precise handling but prolonged hard pulls damage the engine. As an enthusiast, I focus on timely upshifts for safety.

I just started learning to drive, and my instructor taught me that first gear is only used for starting. When the speed reaches 10 km/h, I should shift up to avoid stalling. When driving the practice car, the fastest I went was only 12 km/h, and going downhill at 15 km/h felt unstable and dangerous. Different cars perform differently, but controlling the throttle and clutch is key. As a beginner, I learned to listen to the engine's hum to judge when to shift up in time, protecting the car and saving energy. Simple driving habits cultivate safety awareness.
