California-based Porsche specialist Gunther Werks is set to compete for class honours at this year’s Goodwood Festival of Speed hillclimb with a radical reinterpretation of the legendary Porsche 911 Slantnose, boasting over 1000bhp of power.

Known as Project F-26 – the number denoting the total units that will be produced – this bespoke creation carries a price tag of around £1.2 million each. Drawing design inspiration from fighter jets, the car is a modern reimagining of the distinctive Porsche 935 Slantnose of the 1970s, built upon the 993-generation 911 platform.

Under the rear deck lies a twin-turbocharged, air-cooled Mezger-designed 4.0-litre flat-six engine, co-developed with a motorsport engineering firm. This powerhouse delivers an extraordinary 1067bhp and 750lb ft of torque – slightly exceeding that of the Ferrari 849 Testarossa.

Power is channelled to the rear wheels through a six-speed manual gearbox and a limited-slip differential. With its carbon fibre body keeping the dry weight down to just 1225kg – lighter than a Lotus Emira – the F-26 promises true supercar-level acceleration and dynamics.

Gunther Werks aims for the F-26 to top its class at the Sussex festival’s hillclimb next weekend. The car will be driven by former Formula 1 and Nascar racer Scott Speed, whose experience behind the wheel could prove crucial on the challenging 1.16-mile course.

The company will field the F-26 in the production road car category. For reference, the fastest time in this class at the 2025 event was set by the Koenigsegg Jesko Absolut’s Spear, which completed the climb in just 47.14 seconds.

While Gunther Werks has its sights set on class victory, the outright Goodwood hillclimb record remains in the hands of Gloucestershire-based McMurtry Automotive. Its 1000bhp all-electric fan car, the McMurtry Spéirling, stormed the hill in a remarkable 39.08 seconds back in 2023 – a benchmark that is expected to stand for the foreseeable future.
