The creations from Gunther Werks are truly something special. Their appeal should grow with another model—which is somewhat more accommodating than their hardcore 400R. That said, the new 430-horsepower Sport Touring is still quite quick.

This particular car, unveiled at The Quail, A Motorsports Gathering this past weekend, enjoys several options specific to the Sport Touring. Included are new carbon fiber seats as well as a revised intake plenum for the 4.0-liter Rothsport Racing engine. In the interest of saving weight and sharpening focus, Gunther Werks removed the rear seats, added some decorative carbon panels to spruce up the vacant area, and fitted a fire extinguisher. Though it is a touring model, it still screams track toy.

The comparatively subdued exterior makes the car less of a bold statement than its bewinged brother, but takes inspiration from some of the understated icons like the 2.7 RS with its distinctive ducktail. That said, the a carbon widebody still commands some attention—it's three inches wider at each corner!

The bespoke motor and carbon bodywork certify the Sport Touring as something special, but there's even more to make the aficionado salivate. Massive Brembo brakes are somehow squeezed underneath the Fuchs-style wheels, and JRZ shocks provide the sort of deceleration and roadholding a track scalpel—albeit a slightly comfier version of one—should enjoy.

“The response we received after debuting the first Sport Touring model at The Quail, A Motorsports Gathering this year was incredible,” said Peter Nam, CEO of Gunther Werks. “We thought Rennsport Reunion would be the perfect event to showcase the next Gunther Werks conversion because the event has become synonymous with some of the greatest Porsches ever made.”

Like the 400R, Gunther Werks will only be releasing 25 Sport Tourings, and despite the estimated ~$500,000 price, it's likely these will all be snatched up in a short time. This brand already has some real head-turning power, and with a little more exposure, it might become the one other boutique operation which truly challenges Singer.
