Audi's hard at work expanding the number of models in its portfolio, and one of the most anticipated models of all is the 2008 RS6. With an absurdly wicked 5.2L V10 powerplant that's rumored to receive the turbo treatment to kick out well over 500hp, the RS6 looks like it's preparing to meet the M5 and AMG E-Class head-on.

The folks over at KGP Photography got some good pictures of the RS6 running the 'Ring, and there are subtle differences between it and the S6. The oval-tipped tailpipes and RS4-style rims fare immediate tiopoffs that something's afoot. The front air intake also appears to be tweaked, with its LED lighting apparently removed. The fenders have also been pushed out to accomodate larger wheels.

Does Audi want to rule the luxury world? Looks like it to us, and an RS6 that will be able to take on even the most formidable opponent is part of the plan. The car will duke it out with some pretty stiff marketplace competition, but in the end, we think the ultimate winners are customers who can afford $80,000 to $100,000 vehicles.
