Between the TT and the R8, Audi makes some pretty enticing sports cars. But there's a huge gap in the middle there, and the latest spy shots show a new derivative coming up to close the gap. Tentatively known as the TT-RS, the adrenaline-snorting top-shelf version of the stylish little Audi is expected to pack 350 horsepower thanks to a pair of sequential turbochargers driving all fours via a six-speed manual.

The undisguised bodywork on the test vehicle – spied undergoing hot weather testing in Arizona – looks suitably aggressive, while the output should close the distance between the 272-hp TT-S and the 420-hp R8, as well as compete directly with the 295-hp Porsche Cayman S. We don't have a launch date for the TT-RS confirmed yet, but the super-coupe looks just about ready judging from the spy shots, leaving us to wonder if we might see it as early as the Paris Motor Show in a month and a half.
