Our spy photographers snapped images of Audi’s drop-top RS5 undergoing testing near the Nürburgring.Despite it’ camouflage the new model show an assertive front design with LED headlights. The rear sports the current S5 design while the final production model will have a sportier bumper and a massive dual exhaust system. Much like the facelifted coupe, power will be provided from a 4.2-liter V8 engine producing 331kW and 430 Nm. The engine will be mated to a seven-speed S tronic transmission which should enable the convertible to accelerate from 0-100 km/h in less than five seconds.The new RS5 cabriolet will debut sometime in 2012.
