[Spec 1]

Porsche engineers were recently spotted testing a high-performance version of the Cayman at Germany’s Nurburging circuit, which is expected to be a new ‘Clubsport’ or ‘RS’ model. The car will be a stripped-out racer designed for track use and is expected to make its debut alongside a similar Boxster version this October. There’s a chance that Porsche will also launch a new international one-make race series for the car.

The new Clubsport is expected to be introduced as a special run-out edition before the launch of the next-generation model due in 2011. It will be based on the facelifted Cayman lineup, although the prototype seen in these spy shots is based on the recently introduced Cayman S ‘Sport’ model.

Created in a similar vein to the 911 GT3 RS, the Clubsport will feature a number of weight saving measures such as a stripped-out interior, lightweight body panels, a plastic rear window, forged alloy wheels, and carbon-ceramic brakes.

The engine in the Clubsport will likely be an uprated version of the standard Cayman S’ 320hp (235kW) 3.4L flat-six, complete with VarioCam Plus valve technology and direct-injection.

A six-speed manual gearbox and limited-slip differential are expected to be standard, according to Autocar. Optional extras will be a six-point harness and roll car, plus a fire extinguisher.
