Outside, the GT stands apart from the R8 crowd via numerous carbon fiber aerodynamic bits that also provide additional downforce and high-speed stability. The front fascia is adorned with a double-lip splitter and a winglet on both sides. At rear, there's a large spoiler, diffuser, and a carbon-fiber bumper. The R8's distinctive side blades also get the carbon fiber treatment.

At the core of the interior changes are lightweight fiberglass-reinforced plastic-frame sport seats. Combined, they're a full 69.5 pounds lighter than the stock V-10 seats, accounting for a large chunk of the GT's total weight savings. Unfortunately, these won't be offered in U.S.-market GTs because of federal regulations. European-market GTs are also fitted with a four-point harness instead of traditional three-point belts. The cabin also features a rollcage, fire extinguisher, and copious carbon fiber trim.

We got to take the R8 GT for a spin though the Bavarian countryside and a stretch of unrestricted autobahn a couple of days before the 2010 Paris auto show. Unfortunately, the weather didn't cooperate, with grey skies and wet pavement being the order of the day. Because of the inclement elements, Audi subbed the standard high-performance summer rubber with performance all-seasons. Given the R8 GT's limited production run, Audi can hardly be blamed for wanting to keep its few demo vehicles rubber-side down.
