What Speed for Which Gear?

The gear shift is located on the right side, and most designs are five-speed vehicles. First gear accelerates to around 10 km/h, meaning speeds from 0 to 10 km/h fall within the first gear range. Second gear covers 10-20 km/h; third gear, 20-30 km/h; fourth gear, 30-40 km/h; and fifth gear, 50 km/h up to the maximum speed. Below are the relevant details: 1. Start in low gear, typically using first gear, with an economical speed range of 15-20 km/h. Suggestion: Shift from second to first gear at speeds no higher than 18 km/h. 2. For continuous uphill driving, use low gears (1st or 2nd) to ensure sufficient vehicle power. The economical speed for second gear is 25-40 km/h. Suggestion: Shift from third to second gear at speeds no higher than 35 km/h. 3. For continuous downhill driving, use low gears (2nd or 3rd) to prevent excessive speed. This avoids prolonged brake usage, protecting the brake pads. The economical speed for third gear is 40-60 km/h. Suggestion: Shift from fourth to third gear at speeds no higher than 55 km/h. 4. The economical speed for fourth gear is 60-75 km/h. Suggestion: Shift from fifth to fourth gear at speeds no higher than 70 km/h. Fifth gear is suitable for speeds above 75 km/h.

Having driven manual transmission cars for most of my life, I’d like to share some experience. Shifting gears isn’t just about speed—it’s more about listening to the engine and adapting to driving conditions. Start in 1st gear at low speeds, shift to 2nd around 15 km/h, and 3rd works well between 25 to 40 km/h for smooth acceleration. Above 40 km/h, consider 4th or 5th. But don’t rigidly follow these numbers—lower gears are more flexible when carrying heavy loads or climbing hills, while higher gears can be engaged earlier downhill to save fuel. Remember, a fast-revving or noisy engine usually signals it’s time to upshift. Keeping shifts around 2,000 RPM ensures smooth and safe driving, and forming this habit can save you trips to the repair shop.

I always pay attention to fuel consumption when driving, as the gear shifting strategy directly affects fuel efficiency. Generally, shift to 3rd gear at around 20 km/h, move to 4th gear above 30 km/h, and use higher gears for cruising at speeds over 50 km/h on highways. This keeps the engine RPM between 1500 and 1800, reducing engine load and saving fuel. Avoid delaying shifts until high RPM, especially in stop-and-go city traffic. Timely upshifting minimizes idling and can save half a liter per 100 kilometers. Vehicle condition is also crucial—factors like low tire pressure or heavy use of air conditioning increase load. In such cases, delay shifting slightly to ensure sufficient power. Driving this way long-term will also ease the strain on your wallet.

As a beginner, I was quite confused about gear shifting. Here's a simple guide to starting rules: shift to 2nd gear at about 10 km/h after starting in 1st gear, change to 3rd at 20 km/h, move to 4th at 30 km/h or above, and use 5th or 6th gear on highways. Don't rely too much on the dashboard; listen for the engine sound getting higher to know when it's time to shift. With a few practices, you'll get the rhythm. Different vehicle types, like SUVs with more horsepower, might require slightly delayed shifting, but the basic principle remains the same. Keep your driving smooth and prioritize safety, ensuring the RPM is neither too low nor too high.
