What is the speed range for 4th gear in a manual transmission car?
2 Answers
Fourth gear corresponds to a speed range of 40-60 km/h. The speed ranges for manual transmission gears are as follows: 15 km/h for 1st gear, 25 km/h for 2nd gear, 35 km/h for 3rd gear, and 65 km/h for 5th gear. Below are some related details about gear usage: Relationship between gears and speed: Generally, start in 1st gear and shift to 2nd gear after traveling a few meters. When the speed reaches above 20 mph but below 35 mph, shift to 3rd gear. When the speed reaches above 35 mph but below 45 mph, shift to 4th gear. When the speed exceeds 45 mph, shift to 5th gear. The above applies to standard 5-speed transmission cars. For cars with 6 or more gears, you can upshift one gear for every additional 15 mph increase in speed. Additionally, when shifting gears, pay attention to the engine RPM; it's best to shift when the RPM is around 2500. Introduction to gear usage: Most cars have 5 forward gears and 1 reverse gear, with neutral in the middle. Use 1st gear for starting; 2nd gear for speeds between 20-40 km/h; 3rd gear for speeds between 40-60 km/h; 4th gear for speeds between 60-75 km/h; and 5th gear for speeds above 75 km/h.
After driving for so many years, I've seen quite a few manual transmission cars. The speed in fourth gear usually ranges between 60 to 90 km/h, depending on the car's displacement and power. Generally, in the city, I prefer shifting to fourth gear when the speed stabilizes around 60 km/h, keeping the engine RPM between 2000 to 3000, which is more fuel-efficient and smoother. On the highway, fourth gear can even push beyond 100 km/h, but it's not recommended as it strains the engine at high RPMs. It's best to rely on actual driving feel—when the engine sounds too loud, it's time to shift up or down. Getting the shift timing right not only extends the car's lifespan but also saves a lot on fuel. Experienced drivers know every car is different, so try it out with your own ride.
