Some Porsche 911s are classics. Some are restomods. And some are apparently built for people who think 600-odd horsepower is an embarrassing shortage.

Enter the Gunther Werks Brundle Edition Turbo, a five-car fever dream created with former F1 racer Martin Brundle and his daughter, designer Charlie Brundle.

The paintwork pairs blue and white in tribute to Martin’s racing helmet, with Charlie adding personal references and secret Easter eggs.

Naturally, she’s keeping the latter under wraps. Because apparently, even a car costing an undisclosed fortune needs a spoiler that isn’t its spoiler.

And what a spoiler. The enormous adjustable rear wing is joined by forged-magnesium centre-lock wheels, carbon-fibre everything and an interior where subtlety has clearly been shown the exit.

There’s even a dashboard quote: “The most important bit of the car is the nut holding the steering wheel.” F1 fans will appreciate the joke. Owners may want to check theirs before attempting 860 horsepower.

Power comes from an air-cooled 4.0-litre flat-six producing 860 hp and 610 lb-ft of torque, channelled to the rear wheels through a six-speed manual.

Double-wishbone suspension and carbon-ceramic brakes provide some reassurance that stopping was included in the brief.

Each of the five buyers also gets a matching, signed Bell HP77 racing helmet. Pricing remains a mystery, presumably because faint-hearted bank balances need protection.

The Brundle Edition debuts at Wynn Las Vegas on October 29. Five cars, 860 horses, one very important nut.
