Model is expected to feature a new biturbo V6 engine.

The Audi RS5 Coupe has been spied on the outskirts of the Nürburgring.

Dressed in swirly black and white camouflage, the high-performance model follows in the footsteps of the A5 and S5 but adopts a more aggressive front fascia with larger intakes.  Additional changes are hard to see but it appears the RS5 has extended fender flares which suggests the model could have a wider track.  The car has also been equipped with a four-tailpipe sports exhaust system, large five-spoke alloy wheels, and a short rear trunk with an integrated spoiler.

The interior will largely carryover from the standard model but we can expect an assortment of special touches including a flat-bottomed steering wheel, carbon fiber trim, and plenty of RS5 badging.

Audi has been tight-lipped about the model but previous reports have suggested the car could use a biturbo 3.0-liter V6 engine that produces between 420 and 450 horsepower.  Fans will likely mourn the loss of the naturally-aspired 4.2-liter V8 engine but the new powertrain should help to significantly improve the model's fuel-efficiency.

The 2017 Audi A5 will be unveiled on June 2nd so expect the RS5 to debut sometime next year possibly as a 2018 model.
