Should the clutch be released quickly or slowly when shifting gears?

When shifting gears, the clutch should be released slowly. Introduction to the Clutch: The clutch refers to the separation device between the car engine and the transmission, also known as the clutch. In automatic transmission cars, the clutch is integrated into the transmission, enabling automatic gear shifting. Function of the Clutch: As the name suggests, the clutch serves to separate and connect. It disengages and engages the engine from the wheel transmission system. When the clutch is pressed, the engine's transmission system disconnects from the wheels, preventing the engine's power from reaching the wheels to drive the car. When the clutch is released, the engine's transmission system connects to the wheels, transferring power to the wheels and enabling the car to move.
I've been driving manual transmission cars for over a decade and believe the clutch should be released slowly during gear shifts, especially when starting or driving at low speeds. Releasing the clutch too quickly during shifts can easily cause the car to jerk, resulting in an unstable ride, and may even lead to engine stalling or excessive wear on the clutch plates. Of course, with experience, one can adapt to quicker movements, such as faster clutch release during upshifts while cruising at high speeds, which isn't a big issue. But to ensure smoothness, the key lies in controlling the foot movement—first holding at the half-clutch point to stabilize the RPM, then gradually releasing it completely. I've seen many people release the clutch quickly to look 'cool,' only to end up with a jerky ride that's both unpleasant and unsafe. I recommend beginners start with slow releases to get a feel for it before adjusting. Overall, slow release is fundamental—it helps match the engine and transmission speeds, reduces mechanical stress, and can even save fuel and extend the car's lifespan.
I've gained some experience from daily commuting: release the clutch pedal slowly when shifting gears, don't rush it. Quick release may cause power interruption, making the car jerk as if being towed, which not only makes passengers uncomfortable but also accelerates clutch component wear. For example, during upshifts or downshifts, I'm accustomed to first pressing the clutch to shift, then slightly delaying throttle engagement, and finally releasing the pedal evenly. This technique works particularly well for frequent starts at urban traffic lights – gradually lifting the clutch allows for smooth acceleration and prevents sudden jerks. Over time, I've noticed significantly less clutch disc wear, and even mechanics compliment my maintenance habits. Of course, in extreme situations like track driving, faster releases may be appropriate, but for normal road conditions, slow release is the safer and more reliable choice that also enhances driving pleasure.
I think clutch operation depends on the situation. Generally, it's recommended to release the clutch slowly when shifting gears. For starting off, you must release it slowly to avoid stalling; when upshifting, release it slightly faster but in coordination with the throttle; when downshifting, release it slower to prevent jerking. The key is to find that engagement point—when releasing the clutch slowly, the engine speed remains steady, and the vehicle transitions smoothly. Releasing the clutch too quickly over time can accelerate component fatigue, leading to abnormal noises or sounds. Therefore, it's important to develop the habit of releasing the clutch slowly during normal driving, as it protects your car and reduces frequent malfunctions. Of course, experienced drivers can adjust the speed based on their experience.
