Can You Step on the Throttle While in Half-Clutch?

Yes, you can step on the throttle while in half-clutch. The engine transmits power to the car's transmission via the clutch. The half-clutch state is a brief transitional process during vehicle startup, where the engine speed synchronizes with the transmission speed. To prevent the engine from stalling due to a rapid increase in power during startup, it's appropriate to step on the throttle to increase engine power. The shorter the half-clutch duration, the less wear on the clutch disc. Prolonged half-clutch operation will shorten the clutch's lifespan. Clutch semi-engagement refers to the unstable connection state of the clutch, where the driver gradually reduces the pressure on the clutch pedal, causing the driving disc and driven disc to be in a state of simultaneous rotation and slipping.
I've been driving manual transmission cars for almost twenty years. Of course, you can step on the throttle while half-clutching, but it depends on the timing. When stuck on a long uphill slope, lightly tapping the throttle while half-clutching to prevent rolling back is essential, and it's completely reasonable to rev up to around 1500 RPM in this situation. However, beginners should never imitate experienced drivers by stomping on the throttle in a half-clutch state. Last time my nephew was learning to drive, he revved hard to 4000 RPM while half-clutching, and the clutch plate ended up smoking blue. Actually, apart from starting and hill driving, there's usually no need to drive like this in daily situations—shifting to neutral at red lights is much more convenient. Remember, manual transmission is all about the coordination between throttle and clutch. Adding a bit of throttle while half-clutching during a turn can actually make the car more stable, but this technique takes time to master.
As a driving instructor, I've taught thousands of students how to handle the half-clutch acceleration situation. The key points are actually just three: engine RPM should not exceed 2000, duration shouldn't last more than 5 seconds, and the left foot should lift gently as if stepping on a raw egg. Focus on practicing that critical point during hill starts: when the car shakes, release the handbrake, gradually apply throttle while lifting the clutch, keeping RPM stable around 1200. If you're using half-clutch while queuing in underground parking lots, remember to watch for the warning sign of burning clutch smell. Last week, a student kept using half-clutch for ten minutes straight while climbing a slope, and the clutch plate was completely ruined.
