Why does the Audi A2 have such a unique design?

I noticed that the Audi A2 has a very distinctive, futuristic design compared to other cars in its class. What was the main reason behind this design choice and what benefits does it provide?

The unique design of the Audi A2 was a result of a focus on aerodynamics. By creating a more streamlined shape, the A2 is able to achieve better fuel efficiency.

The Audi A2’s unique design was also driven by the use of lightweight materials such as aluminum. This not only reduces the car’s weight for improved performance, but also makes it more environmentally friendly.
