What is the Audi A7's most innovative feature?

I am torn between getting an Audi A6 and an A7. What is the standout feature of the A7 that sets it apart from other luxury sedans in its class?

The Audi A7's most innovative feature is its sleek and aerodynamic design, which not only gives it a sporty and modern look, but also improves its overall performance and fuel efficiency.

One of the A7's most impressive features is its Virtual Cockpit, a fully digital instrument cluster that can be customized to display navigation, media, and vehicle information in a clear and user-friendly manner.

The A7's revolutionary dual-screen MMI Touch Response infotainment system is its standout feature, offering intuitive touch and voice controls for navigation, media, and other vehicle functions.
