Race-honed, £1.2m recreation of a Porsche legend will go for gold in the hillclimb shootout this week
Californian Porsche tuner Gunther Weeks will bid for class victory on the Goodwood Festival of Speed hillclimb this week with a 1000bhp-plus reimagining of the iconic Porsche 911 Slantnose.
Project F-26 – numbered for the amount of examples that will be built, at around £1.2 million apiece – is a fighter jet-inspired recreation of the distinctive 935 Slantnose of the 1970s, based on the 993-generation 911.
It’s powered by a twin-turbocharged (but still traditionally air-cooled) Mezger 4.0-litre flat six, co-developed with a racing firm to produce a colossal 1067bhp – a little more than the Ferrari 849 Testarossa, for reference – and some 750lb ft of torque.
Sent through a six-speed manual gearbox and limited-slip differential to the rear axle, those outrageous reserves should be good for true supercar performance figures, given the carbon-bodied F-26 weighs only 1225kg dry – less than a Lotus Emira.
Gunther Works is hoping it will take the fastest time in its class when it runs up the hill at the Sussex festival next weekend, with ex-Formula 1 and Nascar driver Scott Speed at the helm.
The company will field the F-26 in the production road car category, the fastest of which at 2025’s event was the Koenigsegg Sadair’s Spear, which ascended the 1.16-mile climb in just 47.14sec.
The outright hillclimb record is still held by Gloucestershire-based McMurtry, whose 1000bhp electric fan car, the Spéirling, went from bottom to top in 39.08sec in 2023 – a record that’s unlikely to be broken for some time.
