Why does the Audi A7 have a lower drag coefficient than other vehicles in its class?

I am aware that the Audi A7 has a significantly lower drag coefficient than other vehicles in its class, and I am curious to know what design features or techniques contribute to this advantage.

The low drag coefficient of the Audi A7 is a result of its meticulously crafted, aerodynamic design. Not only does it enhance the vehicle's performance and fuel efficiency, but it also adds to its sleek and stylish appearance.

One of the key contributing factors to the Audi A7's low drag coefficient is its sleek and streamlined body shape. This minimizes air resistance and allows for smoother and more efficient movement on the road.
