Dual Clutch is a type of transmission system that uses two separate clutches to engage and disengage gears. It consists of one clutch for odd-numbered gears (1, 3, 5) and another clutch for even-numbered gears (2, 4, 6). This allows the engine to be in a different gear than the transmission, which results in smoother shifting and improved fuel efficiency. Dual Clutch Transmissions are commonly used in high-performance cars and racecars due to their quick and precise shift times.
