The 2015 Audi R8 has been spied for the first time.

Caught undergoing testing on the Nürburgring, the redesigned model is instantly recognizable but adopts sportier styling. The prototype is heavily camouflaged but we can see an aggressive front fascia with a prominent grille that is flanked by angular headlights and massive air intakes. Moving further back, there's distinctive sideblades, muscular rear fenders and an active rear spoiler. The model also has slender taillights, an aggressive rear diffuser and a four-tailpipe exhaust system.

The entry-level model is expected to use an updated 4.2-liter V8 engine that develops more than 430 HP (316 kW) and 430 Nm (317 lb-ft) of torque. We can also expect an improved 5.2-liter V10 engine that cranks out more than 525 HP (386 kW) and 530 Nm (391 lb-ft) of torque. Both engines are expected to be connected to a dual-clutch seven-speed transmission and a quattro all-wheel drive system.

The R8 was scheduled to go into production in mid-2014 but several changes have reportedly pushed the launch back until early next year.
