Wearing minimal camouflage, the prototype appears virtually production ready. The overall design stays pretty faithful to the current model, but there's a revised front fascia, larger air intakes and a new four-tailpipe exhaust system.

Engine details remain elusive, but rumors suggest the car will have a turbocharged flat-six with approximately 550 PS (405 kW / 542 hp). It will be connected to a seven-speed manual or an optional PDK transmission, which should ensure this is one of the world's fastest convertibles.
