How does the Audi A2's aerodynamic design impact its fuel efficiency?

I've heard that the Audi A2 has a unique aerodynamic design that helps with its fuel efficiency. Can you elaborate on how it works and its impact on fuel consumption?

The Audi A2 has a sleek and streamlined design specifically engineered to reduce its drag coefficient. This helps the car move through the air more smoothly and efficiently, resulting in better fuel economy. In fact, the A2 has a drag coefficient of just 0.25, making it one of the most aerodynamic vehicles in its class.

The Audi A2 also features innovative features like automatic cooling airflaps that open and close depending on the vehicle's speed, reducing drag and further improving its aerodynamics. This attention to detail in design significantly contributes to its impressive fuel efficiency.
