Why does the Audi A1 have a smaller wheelbase compared to other models?

I noticed that the Audi A1 has a significantly shorter wheelbase compared to other Audi models. Why is this the case and how does it affect the car's performance and handling?

The shorter wheelbase on the Audi A1 allows for better maneuverability and agility, making it easier to navigate through tight city streets or winding roads.

In addition to improved handling, the shorter wheelbase also results in a lighter overall weight for the Audi A1, leading to better fuel efficiency and a more dynamic driving experience.
