@GuntherWerks just pulled the cover off its fastest naturally aspirated car yet at The Quail. Meet the GXR-Evo. Built around the 993-generation 911, it pairs a 455-horsepower naturally aspirated flat-six with a six-speed manual and weighs just 2,385 pounds dry. Double-wishbone front suspension, extensive carbon fiber and serious aero push this well beyond the typical air-cooled formula. Just 15 will be built.
