A remarkably rare 1985 Porsche 959 ‘Vorserie’ prototype, renowned for its groundbreaking technology and storied history, is set to be auctioned by RM Sotheby’s. This particular model, one of only five surviving V-series prototypes, boasts some significant provenance, having been first registered to Ferdinand Piëch, a key figure in Porsche‘s history.
The 959, upon its 1985 debut, redefined the supercar market with its pioneering features like sequential turbochargers, adjustable suspension, intelligent four-wheel-drive and lightweight magnesium wheels. Under the guidance of Helmuth Bott and Manfred Bantle, Porsche’s engineering team created what was then the world’s most advanced supercar at the time.
This V-series prototype, informally known as “V5KOM,” is distinguished by its comprehensive documentation and photography by its factory-assigned test driver, Dieter Röscheisen. Notably, Röscheisen extensively tested V5 at renowned tracks like Ehra-Lessien, Nardo, the Nürburgring and the Contidrome, in addition to long-distance trips across Europe. His detailed records and photographs were later featured in Jürgen Lewandowski’s book, “Porsche 959.”
Originally finished in Grand Prix White with a Dark Grey cloth interior, V5 was used extensively for testing chassis, suspension and traction control before being handed over to Piëch. The prototype features unique elements like a single wing mirror, a hood-sealed fuel-filler cap, and rear fender ducts.
After its testing phase, V5 was used by Piëch as his personal vehicle until 1987, when it was sold to chef Hasi Unterberger. The car then passed through the hands of notable owners, including automotive photographer Rene Staud, who upgraded the interior to leather. In 2021, V5 was acquired by its current owner, bringing its total mileage to approximately 48,143 miles.
The storied vehicle is now set to go under the hammer as part of RM Sotheby’s Monterey Sale and is expected to fetch as much as $2,300,000 USD.
