What is Audi's S tronic transmission and how does it work in the A3?

I'm considering buying an Audi A3, but I'm not sure what their S tronic transmission is and how it works. Can someone explain it to me?

Audi's S tronic is a dual-clutch automatic transmission that combines the convenience of an automatic with the efficiency and sportiness of a manual. It works by utilizing two separate clutches for odd and even gears, allowing for smoother and quicker gear shifts.

I recommend test driving an A3 with S tronic to really experience the difference. It's perfect for both city driving and spirited driving on winding roads. Plus, it's more fuel efficient than a traditional automatic.
