The 911 GT3 RS is already one of the most extreme road cars you can buy. A 4.0-litre naturally aspirated flat-six screaming to 9,000rpm, 525 horsepower, a 0-60 time in around three seconds, and aerodynamics so aggressive the car generates more downforce than some race cars. The base price sits north of $230,000, and with options that figure climbs well past $300,000. This particular example, built by Porsche’s Sonderwunsch programme in collaboration with Porsche Centre Geneva, is a one-off. For good reason.

This stunning GT3 RS is finished in Macadamiametallic, a warm, deep nutty tone sourced from Porsche’s Paint to Sample range. Macadamia, of course, is the nut that ends up in the finest chocolates. Whoever ordered this car clearly knows that. The carbon fibre components, ordinarily black, have been given a clear coat infused with brown pigments developed exclusively for this build, resulting in a shade you’d find on a praline, not a race car.

It is one of the first times a manufacturer has tinted carbon at this level for a single customer. Pastelorange accents appear on the Weissach wing end plates, the LED headlight rings and the brake calipers, while the interior wraps the occupants in Truffle Brown leather and Race-Tex orange stitching running throughout.

Porsche has been making colour a competitive advantage for decades. Rubystar, Viola Metallic, Riviera Blue, the legendary Gulf Orange that became so synonymous with Porsche’s racing identity that other manufacturers started borrowing it. Ford’s Gulf-liveried GT supercar owes its cultural power almost entirely to what Porsche and Gulf built together at Le Mans in 1968.

The Sonderwunsch programme, revived from its 1970s origins, exists precisely for when a customer wants something that cannot be ticked from a configurator. The craftsmanship takes months, and the cost is undisclosed. Which usually means it’s considerable. The irony is that the 911 GT3 RS was built to be driven hard, ideally on track. But this is one that might never see that day thanks to how special it’s turned out.
