The 1000 HP Porsche Slantnose Revival: Guntherwerks F-26

Porsche has always had a way of making even the most unusual designs into legends. The Slantnose, with its flattened front end, may not have been universally loved, but it earned its place in history thanks to the Porsche 935 race car. Now, Guntherwerks is carrying that spirit forward with something wild, raw, and modern—the Project F-26.

Unveiled during Monterey Car Week at The Quail, the Project F-26 blends inspiration from Porsche’s past with futuristic performance. Under the hood sits a Rothsport Racing developed air-cooled 4.0-liter twin-turbocharged flat-six engine producing an astonishing 1000 horsepower and 750 pound-feet of torque. All of that power is channeled through a 6-speed manual transmission and delivered to the rear wheels via a limited-slip differential.

To handle such performance, Guntherwerks engineered a motorsport-grade cooling system, including a race-style flat fan, a bespoke carbon fiber intake, and a 935-inspired exhaust with external wastegates. Beyond the sound and fury, the chassis has been heavily reworked. The F-26 weighs only 2700 pounds, supported by Continental ExtremeContact Force tires measuring 335 millimeters in the rear and 295 millimeters in the front. A double-wishbone front suspension, adaptive JRZ dampers, traction control, and motorsport ABS make sure this machine does not just go fast in a straight line but remains planted through every corner.

The design is both aggressive and elegant, ditching the old pop-up lights for fixed carbon fiber housings and adding a massive wing for downforce. Side intakes remind you this is race-bred, and inside, the mix of exposed carbon fiber, Alcantara, and custom leather shows Guntherwerks’ dedication to craftsmanship. Even with all the raw performance, modern touches like Apple CarPlay integrated into a Porsche Classic radio keep it usable for everyday enjoyment.

Production is limited to just 26 cars, each tailored to the buyer. Pricing has not been revealed, but expect it to start well north of $1 million. For Guntherwerks, this is not just about numbers—it is about building one of the most extreme Porsche-based creations ever imagined.
