Why does the Audi A2 have a higher drag coefficient than other Audi models?

I noticed that the Audi A2 has a drag coefficient of 0.3, which is higher than other Audi models. Is there a specific reason for this difference?

The unique design of the Audi A2, specifically the curved roof and angle of the rear window, contribute to the higher drag coefficient compared to other Audi models. This makes the A2 more aerodynamically efficient at higher speeds.

The Audi A2 was designed to be a more compact and lightweight vehicle, which meant making sacrifices in certain areas such as aerodynamics. However, this allows for better fuel efficiency and lower emissions.

The Audi A2 was first released in 1999, which was a time when aerodynamics and fuel efficiency were not as much of a priority in the automotive industry. As newer models have been released, Audi has made improvements to the overall aerodynamics of their vehicles.
