What is the speed for shifting from third gear to fourth gear?
2 Answers
The corresponding speed for shifting from third gear to fourth gear is between 30-60km/h. Below is additional information about gear shifting: 1. RPM: The optimal gear shift timing for most cars is when the engine reaches 2000r/min, preferably not exceeding 2500r/min. For some high-displacement, high-power engines, the maximum efficiency range may be slightly delayed, so shifting around 3000r/min can be considered. 2. Engine: Different vehicles have engines and transmissions that perform differently. Drivers can determine the shift timing by listening to the engine sound. Generally, if the engine sound is dull, it indicates that it's time to upshift.
I've been driving manual transmission cars for over a decade. Shifting from third to fourth gear usually happens between 50 to 60 km/h, depending on the car. For example, with my old Volkswagen, the gear change is smoothest around 3000 RPM, providing quick acceleration without wasting fuel. For smaller 1.6L engines, shifting at lower speeds is fine, but larger engines like a 2.0T might need to rev up to 3500 RPM to avoid lugging. Pay attention to the engine sound changes – when you hear a slight roar, it's time to upshift. Beginners can rely on the tachometer; move when the needle reaches the mid-range. This habit saves the engine and ensures safety, especially in urban areas with frequent traffic lights. Each car has its own characteristics, and you'll naturally figure it out after driving for a month.
