What is the speed range for fourth gear?
3 Answers
The speed range for fourth gear is typically 40-60 km/h. For most vehicles, the optimal gear shift timing occurs when the engine speed reaches 2000 rpm, preferably not exceeding 2500 rpm. Speed ranges for gears 1 through 5: First gear is for starting, with speeds generally between 0-5 km/h; second gear corresponds to 5-20 km/h; third gear to 20-40 km/h; fourth gear to 40-60 km/h; and fifth gear to 60-100 km/h. Gear shifting precautions: Do not look down at the gear lever while shifting. When shifting gears, there's a tendency to instinctively look down at the gear shift. While looking down, the left hand holding the steering wheel may unconsciously apply a downward force, which can easily cause the vehicle to veer off course. If the speed is slightly high, this could potentially lead to danger. Proper clutch coordination is essential when shifting gears. Whether using the double-clutch shifting method or the single-clutch shifting method, it's important to fully depress the clutch pedal when shifting. After completing the shift but before fully releasing the clutch, gently press the accelerator, then slowly release the clutch, maintaining a semi-engaged state until the vehicle speed stabilizes before completely releasing the clutch. Control speed before shifting. Gear shifts should be determined based on vehicle speed. When upshifting, first increase the speed; when downshifting, first reduce the speed. It's worth noting that when downshifting, to prevent mechanical wear, it's best to use the double-clutch method.
Bro, when it comes to fourth gear speed, there's no fixed number—it depends on what car you're driving. I've been driving manual for over a decade, and in small city cars, fourth gear at 50-60 km/h feels smooth; on the highway, you can push it past 90 km/h. The key factors are engine RPM and gear ratios—at 1500 RPM you might be doing 50 km/h, but at 3000 RPM you could hit 100 km/h. Tire size and vehicle weight also play a role—lightweight sports cars can pull higher speeds. Don't trust random numbers online—your best bet is to check the owner's manual or test it yourself during a test drive, otherwise you're just wasting effort.
Talking about the 4th gear in manual transmissions, I feel this thing varies quite a bit. Compact cars have tighter gear ratio designs, typically cruising between 60-70km/h; whereas larger SUVs or trucks feature extended gear ratios, easily hitting 80-100km/h without breaking a sweat. Engine output power also plays a role—low-power engines tend to vibrate at higher speeds, while high-power ones remain smooth. A practical tip while driving is to keep an eye on the tachometer; maintaining 1500-3000rpm in 4th gear is the sweet spot. Vehicle maintenance impacts speed too—rusty or worn chains can slow you down. Don’t overlook these minor issues; regular check-ups save headaches.
