The rear window is gone, replaced by a shark fin that stretches back from the roofline. It's the first thing that stops you in your tracks when you look at the GXR-Evo from behind — from the front it's still that familiar 993 silhouette, but the rear has practically been rewritten.
The GXR-Evo debuted at Monterey Car Week as Gunther Werks' fastest naturally aspirated creation to date, limited to just 15 units worldwide. The body is built entirely from carbon fiber, bringing dry weight down to 2,386 pounds — 210 pounds lighter than the brand's own Coupe. A deeper splitter sits below the front bumper, with vents in the fenders channeling airflow away from the front wheels; an enlarged rear wing at the back practically takes over the visual center of gravity, while carbon fiber rear quarter windows direct air toward the engine. The 911's shape is still there, but every surface now serves function more directly.
Mounted at the rear axle is a 4.0-liter naturally aspirated flat-six, co-developed with Rothsport Racing, producing 455 horsepower and revving to nearly 9,000 rpm — a number that says everything about the driving experience Gunther Werks is after. Power still runs through a six-speed manual. In the team's own words, there are easier ways to build a faster modern performance car, but they chose to keep everything centered around the air-cooled engine, clutch pedal, and shift lever. That old-school mechanical vocabulary, wrapped inside a much lighter body covered in track-grade aero elements, is what makes the GXR-Evo genuinely interesting.
