The first pictures of the Volkswagen Golf R Cabriolet have been spied while its prototype was undergoing testing at 2011 Worthersee tuning show. The Golf R Cabriolet was previewed as a concept last year, and is set to become the quickest and meanest Volkswagen convertible in history. From the leaked images, it is obvious that the prototype model features the same styling cues and parts as the GTI Cabriolet in all areas, but it sports the larger and distinctly styled five-spoke alloy wheels and the much larger disc brakes up front. Even though the prototype has a low-key appearance, the production model is expected to feature an aggressive front fascia, aerodynamic side skirts and a center-mounted dual exhaust system. Besides, a sport-tuned suspension alongside a high-performance brakes and an upgraded interior are included.

Coming to its power specifications, the new Golf R Cabriolet will be powered by a 2.0-litre turbocharged petrol engine that generates 270 PS (199 kW / 266 hp) and 350 Nm (258 lb-ft) of torque. The power to the four wheels will be sent via a six-speed manual or six-speed dual-clutch DSG transmission like the Golf R hatch. Despite the same body panels and badges in the current Golf Cabriolet models, the new model features larger breaks and alloy wheels that confirm the bodywork hides the most powerful and sporty soft-top variant to date.

According to the sources, the Golf R Cabriolet would act as a send-off for the Golf VI range, when the next-generation Golf VII is due to be unveiled at the 2012 Paris motor show in September. Meanwhile, the current-generation Golf R should remain in the markets for some time until a high-performance replacement is launched. The Golf R Cabriolet arrives hot on the heels of the Golf GTI Cabriolet that debuted at the 2012 Geneva Motor Show in March.
