How much does the needle drop during hill start?

When the clutch is in the semi-engaged state during a hill start, the engine speed will be maintained at around 1000 RPM. Here is the relevant information: 1. Hill start: A hill start is part of the on-site test for the second subject of the driver's license examination, which involves starting a vehicle parked on a steep slope. 2. Hill start test rules: (1) If the vehicle stops and the front bumper (for cars) or front axle (for motorcycles) is not aligned with the pole line, and the deviation exceeds 50 cm, it results in failure. (2) If the vehicle stops and the front bumper (for cars) or front axle (for motorcycles) is not aligned with the pole line, but the deviation does not exceed 50 cm, 10 points are deducted (originally 20 points). (3) If the vehicle stops and the body is more than 30 cm away from the road edge line, 10 points are deducted (originally 20 points). (4) If the vehicle starts and rolls back between 30 cm and 50 cm, 20 points are deducted. (5) If the vehicle starts and rolls back more than 50 cm, it results in failure. (6) If the engine stalls on the slope, 20 points are deducted. (7) If the vehicle does not start within 30 seconds after stopping, it results in failure due to timeout.
When I first started learning to drive, I was particularly afraid of hill starts. After several attempts, I kept stalling the car. Later, my instructor told me the key was to watch the tachometer. If the needle drops below 800 RPM during the start, the car is likely to stall. At this point, quickly release the clutch and give it some gas to stabilize it around 1200 RPM. Too low, and the car won't have enough power and might roll backward; too high, and it wastes fuel and damages the engine. Remember to keep your right foot lightly on the brake, slowly release the clutch with your left foot, and then gently press the accelerator with your right foot—don't rush. After practicing this a few times, you'll get the hang of it. Otherwise, rolling backward on a slope is very dangerous and could lead to a rear-end collision. Now, during my daily commute, I often encounter steep hill starts, and maintaining the RPM between 1200 and 1500 ensures everything goes smoothly and safely.
Having driven manual transmission cars for over a decade, I've learned that hill starts require special techniques. The sweet spot is when the RPM needle drops to around 1,000 - that's when it's smoothest. It's normal for RPM to dip slightly when initially releasing the clutch. As long as it doesn't fall below 800 RPM, the engine won't stall. Maintaining between 1,000-1,300 RPM is both effortless and effective. If it drops below this range, it means either insufficient throttle or releasing the clutch too quickly - immediate adjustment is needed. Conversely, revving above 2,000 RPM wastes fuel but won't cause mistakes. I recommend beginners practice on flat ground first before attempting real hills, using the parking brake to prevent rollback. Rely more on feel than just watching the RPM gauge for smoother driving. Also, regular vehicle maintenance matters - don't overlook tire wear as it affects traction during starts.
