Audi Quattro Concept Teased

Audi is preparing to unleash another iteration of its Quattro showcar concept, teased today with a handful of red-hot sketches.

And this time, it's expected to go into production, slotting into the Audi line-up just below the R8 supercoupe.  

Audi last taunted fans with the hope of a new sub-R8 performance hero in 2010 when it celebrated the 30th anniversary of its legendary Ur-Quattro coupe.
