A dual-clutch transmission (DCT) is a type of automatic transmission that uses two separate clutches for odd and even gear sets. This design allows for faster gear shifts compared to traditional automatic transmissions, as one clutch engages while the other is pre-selecting the next gear. DCTs are commonly found in high-performance vehicles and some everyday cars, providing a balance between efficiency and sporty driving. DCTs operate similarly to manual transmissions but without the need for a clutch pedal. They can offer improved fuel efficiency and quicker acceleration, making them popular in sports cars and racing applications. Overall, DCTs enhance the driving experience by combining the convenience of automatics with the responsiveness of manuals.
