Porsche lined up a particularly special 70th birthday present for Louise Piëch, daughter of company founder Ferdinand Porsche. To mark the occasion, on 29 August 1974, the factory gifted her a 911 Turbo prototype (chassis 9115600042). Even more special, this example of the first road-going 911 to feature forced induction was quite different from the final model that would enter production the following year. For starters, it was based around a narrow Carrera chassis rather than gaining the full-fat Turbo’s eventual and distinctive wide stance. In addition, a turbocharged 2.7-litre flat-six was initially installed rather than a 3-litre powerplant, plus the tachometer showed an ambitious red line of 10,000 rpm.

Finished in silver over a tartan interior, as chosen by Mrs Piëch, the prototype was completed at the Zuffenhausen factory on 17 July 1974. She evidently enjoyed driving “911 Turbo No. 1” greatly. Upon handing the car over to the Porsche Museum four years later, the odometer recorded nearly 32,000 kilometres from Mrs Piëch’s touring of continental motorways.

With 2024 marking 50 years since the original 930-generation 911 Turbo was revealed to the public at the Paris Motor Show in October 1974, Porsche fittingly commissioned the one-off ‘911 Turbo Exclusive Manufaktur’ offered here. Presented in GT Silver, this car is a loving modern-day interpretation of Mrs Piëch’s personal prototype. The stunning homage comes as a result of a collaboration between Style Porsche, Porsche Exclusive Manufaktur, and Porsche Middle East and Africa FZE in an exercise showcasing the Sonderwunsch request program, which provides bespoke customisation services to create unique special editions.

Unveiled at the Icons of Porsche festival held in Dubai in November 2023, this car is fitted with a host of Exclusive Manufaktur options. These include the Sport Design Package, which notably adds upturned tips for the rear wing, more pronounced side sills, and an aggressive restyling of the extended front bumper. Meanwhile, the side strakes and mirrors are painted to match the body colour. To authentically recreate the look of Mrs Piëch’s 1974 prototype, Style Porsche designers in Weissach have added the Austrian autobahn decal on the right-front wing. Porsche Classic also provided special permission for the script from the first-ever production 911 Turbo to be reused for the rear badge. The exterior configuration is capped off by black five-spoke wheels that hark back to the famous Fuchs alloy design.

With the Heritage Design Classic package selected, the interior features retro-style green illuminated dials for the tachometer and Sport Chrono dial. The upholstery for the remastered Turbo compromises two-tone Lipstick Red and black, while the seat centres and door cards are trimmed with red and blue tartan trim just as Mrs Piëch originally requested. Like the rear badging, the seats are capped off with original Turbo lettering embroidered into the headrest.

While the appearance is a clear tribute to Porsche’s past, the dynamics are at the leading edge. As a 992-generation 911 Turbo, the car boasts a 3,745-cc six-cylinder boxer engine enhanced by symmetrical turbochargers to deliver 580 PS. With that power transmitted to all four wheels via an eight-speed PDK transmission featuring an aluminium gear selector, the sprint to 100 km/h takes just 2.8 seconds while the top speed is 320 km/h. That considerable performance is accessed by unlocking the car with a bespoke dual-finish key that features the tartan pattern and GT Silver colours.

Showing delivery use only, with the odometer displaying just 35 kilometres at the time of cataloguing, the sale of this 911 Turbo ‘Exclusive Manufaktur’ is particularly special. A seldom-offered opportunity to become the first owner of a one-off Porsche that celebrates 50 years of the manufacturer’s forced-induction flagship, here is an opportunity for marque enthusiasts and supercar collectors alike that’s not to be missed.
