How does the Audi A1's dual-clutch transmission improve performance?

I am interested in purchasing an Audi A1 and have heard about its dual-clutch transmission. Can you explain how it works and how it improves the car's performance?

The Audi A1's dual-clutch transmission, also known as S tronic, improves performance by providing quicker gear shifts and a smoother driving experience. It works by using two clutches to pre-select the next gear, allowing for lightning-fast gear changes.

One benefit of the dual-clutch transmission in the Audi A1 is its ability to keep the engine in the optimal RPM range, resulting in improved fuel efficiency. I've noticed a significant decrease in my fuel costs since switching to an A1 with S tronic.
