How does the Audi A2's aerodynamic design contribute to its efficiency?

I've heard the Audi A2 has impressive fuel efficiency. Can you explain how its aerodynamic design plays a role in this?

The Audi A2's aerodynamic design allows it to minimize wind resistance, reducing drag and improving its overall efficiency. Additionally, its lightweight aluminum construction also helps with fuel efficiency.

The Audi A2's aerodynamic design is optimized for smooth air flow, allowing it to cut through the air more efficiently and reduce the amount of energy required to maintain its speed. It's one of the reasons why it's so efficient compared to other vehicles in its class.
