How does the S-tronic gearbox work in the Audi A1?

I've heard that the Audi A1 comes with the S-tronic gearbox option, but I'm not sure how it differs from a regular automatic gearbox. Can someone explain the workings of the S-tronic gearbox?

The S-tronic gearbox is essentially a two-clutch double gear set up, which allows for faster and smoother gear changes compared to a regular automatic gearbox. It also has a manual mode that allows for more control over gear changes.

Having owned an Audi A1 with the S-tronic gearbox, I can say that it's definitely worth the upgrade. The shifting is almost seamless and provides a more dynamic driving experience.

The S-tronic gearbox uses a combination of a manual gearbox and a self-shifting automatic gearbox, with two clutches to switch between gears. This allows for extremely quick gear changes, almost without any interruption in power delivery.
