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. This results in smoother acceleration and improved performance. DCTs are commonly found in high-performance vehicles and some everyday cars, offering a balance between manual control and automatic convenience. They enhance fuel efficiency and driving dynamics, making them popular among car enthusiasts and manufacturers alike.
