Why does the Audi A7 have a lower drag coefficient compared to other luxury cars?

I've noticed that the Audi A7 is often touted for its aerodynamic design. Can you explain why this is significant and how it compares to other luxury cars in terms of drag coefficient?

The Audi A7 has a very sleek and streamlined design, with a drag coefficient of only 0.27. This means it has less resistance and can cut through the air more easily, resulting in improved fuel efficiency and overall performance. Other luxury cars may have a higher drag coefficient, making them less efficient and potentially affecting their top speed and handling.

The A7 utilizes advanced technologies such as active grille shutters, underbody shields, and a rear spoiler which can automatically adjust based on driving conditions, to further reduce drag and improve efficiency. This is just one of the many ways that Audi has prioritized aerodynamics in the design of their vehicles.
