Why does the Audi A2 have a high drag coefficient?

I recently purchased an Audi A2 and was surprised to learn that it has a relatively high drag coefficient of 0.28. Can someone explain the reasons behind this and how it affects the car's performance and efficiency?

The Audi A2 has a unique design with a flat underbody and smooth side panels, which increases its aerodynamic drag. To improve performance and efficiency, you can consider installing a front spoiler or side skirts.

The A2 was designed in the early 2000s when reducing drag was not a top priority. Its boxy shape and large windshield also contribute to its high drag coefficient. To minimize drag, avoid adding roof racks or accessories that increase the car's frontal area.

While a high drag coefficient may seem like a disadvantage, it also means the car has a larger frontal area, providing more space and comfort for passengers. To improve aerodynamics, keep the windows closed and try to maintain a consistent speed on the highway.
