The quad-ring obsessives over at Fourtitude have the inside scoop on what Audi plans to unveil in Detroit this January, and enthusiasts stand to benefit from a duo of performance products in the form of an R8 concept and what's likely to be the production version of the TT-S.

Audi's midship masterpiece has only been on the market a few months, but it's been all but confirmed that bigger things are on the way. The rendering above was supposedly released to a handful of lucky press outlets a few weeks back and it obviously foretells a future convertible variant of the R8. Rumors about a powerplant upgrade in the form of a V10 are also circulating, but we think its doubtful that Audi would blow it all on one show.

While the R8 convertible is pure motoring pr0n, the TT-S is proof that Audi is taking its performance offerings seriously. The exterior benefits from a number of S-line goodies originally spied at the 'Ring, while power is expected to come courtesy of the European S3's 265 HP 2.0-liter turbocharged four. The combination of a more aggressive suspension, larger brakes and upgraded rolling stock is sure to capitalize on the TT's already nimble chassis.

Head on over to Fourtitude for a rendering of the TT-S and to get an eyeful of the R8 cabrio concept.
