Better Peugeot 308 RC-Z Pics Reveal Retractable Rear Wing

Our spy photographers have once again managed to catch Peugeot's upcoming 308 RC-Z coupe undergoing testing in Europe.

Unlike the black RC-Z prototype we brought you earlier, these new pictures reveal more details about the car's overall shape as well as its retractable rear wing. Design wise, the production model appears virtually identical to the 308 RC-Z Concept that first appeared at the Frankfurt Motor Show in 2007. The small patch of camouflage on the roof even suggests that a version of the concept's "double bubble" roof may be destined for production.

Expected to be launched in 2010, the RC-Z will come equipped with several of the 308's more powerful engines including a possible high performance unit with 250hp (184kW).

Although Peugeot hasn't announced when the car will be officially unveiled, timing seems to suggest that it could make an appearance at the Frankfurt Motor Show in September.
