What is the minimum speed in second gear without accelerating?
2 Answers
The minimum speed in second gear is approximately 10 kilometers per hour (10 km/h). If the vehicle speed drops below 10 km/h, continuing to drive in second gear may easily cause the engine to stall. Beginner drivers often determine gear shifts based on vehicle speed, but in reality, each gear does not have a specific speed requirement; instead, it depends on the engine RPM. Below is an introduction to engine RPM: 1. Starting in first gear: Engine RPM around 1000-1500, vehicle speed at 10 km/h, then shift to second gear. 2. In second gear: Accelerate, engine RPM around 1500-2000, vehicle speed reaches 30 km/h, then release the accelerator and shift to third gear. 3. In third gear: Accelerate, engine RPM around 1500-2000, vehicle speed reaches 40 km/h, then release the accelerator and shift to fourth gear. 4. In fourth gear: Accelerate, engine RPM around 1500-2000, vehicle speed reaches 50-70 km/h, then release the accelerator and shift to fifth gear. 5. In fifth gear: Accelerate, engine RPM around 1500-3000, vehicle speed reaches 80-120 km/h.
As a veteran driver with over 20 years of manual transmission experience, I've encountered this situation many times. When coasting in second gear without throttle input, the car's minimum speed typically ranges between 15 to 20 km/h, as the engine idle speed sits around 700 rpm - just enough to keep the vehicle moving. Going slower may cause engine shuddering or even stalling, especially noticeable on inclines. I recommend beginners practice on flat, open roads, but never force it to avoid vehicle damage. For safety, immediately apply slight throttle or downshift when speed drops to ensure smooth transition. Remember each engine behaves differently - my old Santana usually stabilizes at 18 km/h while my friend's Hyundai might handle slightly lower speeds. Regular idle speed checks can also prevent potential issues.
