ZUFFENHAUSEN, GERMANY / EuroWire / — Porsche has presented a one-off 911 GT3 RS created through its Sonderwunsch programme, combining the track-focused sports car with a bespoke design treatment inspired by haute couture. The vehicle is finished in Macadamiametallic from the Paint to Sample range and uses brown-tinted carbon fibre elements developed for the project, giving the model a distinct visual identity while retaining the technical basis of the current 911 GT3 RS series model.
The project was carried out in collaboration between Porsche Centre Geneva and Porsche Sonderwunsch in Zuffenhausen, where the brand’s individualisation work includes detailed exterior and interior commissions. The car applies a restrained palette of deep metallic brown, tinted carbon, orange accents and Truffle Brown cabin materials. Its design focus is based on contrasts between the GT3 RS bodywork, exposed carbon surfaces and colour elements selected to align with the fashion-inspired brief.
The underlying 911 GT3 RS remains the road-approved high-performance model built around a 4.0-litre naturally aspirated six-cylinder engine. Porsche lists output at 386 kW, or 525 PS, with acceleration from zero to 100 kilometres per hour in 3.2 seconds and a top speed of 296 kilometres per hour. WLTP data for the GT3 RS lists combined fuel consumption of 13.2 litres per 100 kilometres and CO2 emissions of 299 grams per kilometre.
Bespoke exterior details
The exterior treatment centres on Macadamiametallic paint and tinted carbon components whose clear coat contains brown pigments developed specifically for this build. The carbon treatment is applied to selected body elements, including the rear wing, where Weissach branding appears on the side plates. Orange Porsche lettering adds a contrasting colour point on the wing, while Pastelorange accents appear in the rings of the LED headlights to link the exterior details.
Inside, the cabin carries the same colour direction through Truffle Brown leather and Race-Tex, supported by orange decorative stitching. Porsche said the interior and exterior were aligned to create consistency across materials, colours and surfaces. The build uses numerous components made for the project, with the Sonderwunsch work extending beyond standard option selection into detailed coordination of finishes, upholstery and visible carbon elements across the vehicle.
Sonderwunsch programme context
The Sonderwunsch programme is Porsche’s modern interpretation of a customer personalisation offer that dates to the late 1970s. It allows individual commissions to be developed with customers and realised by the company through factory-backed processes. For new vehicles, the offer can include bespoke Sonderwunsch options integrated into production, while Paint to Sample Plus allows customers to request the development of an individual exterior colour.
The programme also supports vehicle refinement after production, including redesigned interiors and exteriors or technically individual projects under the Sonderwunsch Factory Re-Commission offer. For older vehicles, the offering can include restoration as part of the process, while restoration remains available separately. The Macadamiametallic 911 GT3 RS demonstrates the programme on a current GT model, combining series production performance data with project-specific materials, colours and craftsmanship.
