What is the speed for shifting from third gear to fourth gear?
4 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.
I always try to save some fuel when driving, so I shift from third to fourth gear relatively early, maintaining a speed between 40 to 55 km/h. At this point, the engine RPM is around 2500, right in the efficiency zone, ensuring complete combustion and lower emissions. When driving my small-displacement Ford, I shift at a slower speed of 45 km/h when climbing hills, and a bit earlier at just over 40 km/h on flat roads. Don’t rush to accelerate; easing off the throttle slightly before shifting makes it much smoother. Also, pay attention to the indicator lights on the dashboard—some newer models flash a green light to signal the optimal shift timing. Once you develop this habit, your car will experience less wear, and the annual inspection data will look better. Driving this way long-term can also help your fuel tank last longer between fill-ups.
When driving performance cars, I prefer accelerating to around 65 km/h in third gear before shifting to fourth, with the engine revving above 3,000 RPM for maximum thrill. Take my modified Civic for example - the power fully unleashes in the high-rev zone, maintaining thrust during gear changes. Shifting too early just makes the car feel sluggish, especially during overtaking or track driving. I recommend waiting until the engine roars before shifting. For city driving with frequent traffic lights, be more flexible - shift at around 55 km/h to prevent engine strain. Listening to the exhaust note is key - shift when the pitch rises sharply. Most stock cars should be operated below 4,000 RPM before fuel cut-off to preserve gearbox longevity.
