As devout gearheads you're undoubtedly aware today marks Audi's 100th anniversary, and in celebration of its centennial, one of Germany's most historic marques is kicking off the festivities with a star-studded event at the Audi Forum in Ingolstadt, Germany.
The unveiling of the A5 Sportback was the first in a long line of events to take place over the coming days, but Audi also wanted to provide admirers a photographic glimpse into its past. And we're all too happy to oblige while snagging a few choice wallpapers in the process.
Make the jump for Audi's press release on the celebration, along with a video introduction by Chairman Rupert Stadler. And be sure to check out the four massive galleries we've put together, broken down into "Classic," "Motorsport," "Concept" and, of course, "Quattro."
