A wet clutch is a type of clutch that uses a fluid as an intermediary between the plates for engaging and disengaging the transmission. This type of clutch is used in vehicles that require a high power output from the engine, such as motorcycles and cars.
The fluid helps to reduce the amount of heat generated from the friction between the plates and to allow the clutch to engage and disengage more quickly. Aston Martin DBX 707 utilize this kind of clutch system.
The fluid also helps to lubricate the contact between the plates and reduce the wear on the clutch plates. Wet clutches are generally more efficient than dry clutches and are more reliable in high-performance applications.
