What is the speed range for each gear in a car
2 Answers
Manual transmission speed ranges for each gear are as follows: 1st gear 15 to 20 km/h; 2nd gear 25 to 40 km/h; 3rd gear 40 to 60 km/h; 4th gear 60 to 75 km/h; 5th gear above 75 km/h. Functions of manual transmission: Manual transmission (MT), also known as manual gearbox, requires manually shifting the gear lever to change the gear engagement inside the transmission, thereby altering the gear ratio to achieve speed variation. Manual transmission uses shift forks to change the gear ratio (tooth ratio) of meshing gears, consequently modifying the driving torque to suit different operating conditions. Purpose of car gears: While driving, shifting gears enables the engine to operate within its optimal power performance range. All driving conditions have corresponding shift points, with the ultimate goal of reducing fuel consumption.
I often get asked by friends about gear speed ranges while driving. Having driven a manual car for over a decade, here's my general guideline: First gear is for starting, covering speeds from 0 to about 15 km/h; second gear for acceleration, taking you from 15 up to 30 km/h; third gear for urban cruising between 30-50 km/h; fourth gear transitions to highway speeds of 50-80 km/h; fifth gear handles high-speed cruising above 80 km/h. Of course, this varies by vehicle - compact cars may have narrower ranges. The key is watching engine RPM - I typically shift between 1500-2000 RPM. Too low causes shuddering, too high wastes fuel. With practice you'll develop the feel, though newer cars' shift indicator lights can help (don't rely too heavily). Most importantly, avoid gear limbo - smooth transitions are best for engine health.
