New teaser video from Audi shows a few of the new design lines of the upcoming next-generation A6.

Here's a very brief and not terribly revealing teaser video released by Audi for the upcoming next-generation Audi A6.

We get to see some hints of its overall shape and get a glimpse at some of its new design lines.

The good news is that Audi will be releasing more details, and hopefully, more images, this week (December 1st).

With the A6 slated to go into production before the end of the year, there's not much more time left for it to hide in the shadows. A full product release is expected early in 2011.

The next-generation A6 will be built at Audi's Neckarsulm plant alongside sibling models such as the A8, A8 L (extended-wheelbase), the A7 Sportback and the R8 Spyder.

The next-generation A6 is a very important launch for the premium German brand and for the VW Group in general. The mid-level sedan accounts for a huge chunk of Audi's revenue and Audi has been the largest profit earner in the VW Group as of late, with the German automaker counting on its Ingolstadt-based premium brand to deliver the goods for the company's bottom line.
