Answer: The biggest difference between the two is that the torque transmission of the wet clutch is achieved through the wet clutch friction plate immersed in oil, while the dry clutch transmits torque through the friction plate on the clutch driven plate. The wet clutch theoretically has a longer service life than the dry clutch and can withstand greater torque. Since the dry clutch saves the related hydraulic system, the wet clutch consumes more energy during gear shifting friction than the dry clutch, so the dry system greatly improves fuel economy.
