With an estimated auction value of $1,250,000 to $1,700,000, the 959 Speedster is poised to make waves in the collector car market. This article delves into the origins, significance, and allure of this automotive unicorn, exploring why it stands as a pinnacle of Porsche’s legacy.
The Porsche 959: A Technological Trailblazer
To understand the significance of the 959 Speedster, one must first appreciate the Porsche 959 itself. Introduced in 1986, the 959 was Porsche’s answer to the burgeoning supercar wars of the era, competing with the likes of the Ferrari F40 and Lamborghini Countach. However, the 959 was not merely a contender; it was a revolutionary leap forward. Designed as a homologation special for Group B rally racing, the 959 combined cutting-edge technology with breathtaking performance, earning its place as one of the most advanced cars of its time.
The 959 boasted a twin-turbocharged 2.85-liter flat-six engine, producing 444 horsepower and 369 lb-ft of torque. Its all-wheel-drive system, adjustable suspension, and lightweight construction—featuring aluminum and Kevlar panels—set new benchmarks for performance and handling. The car’s top speed exceeded 195 mph, making it the fastest production car in the world upon its debut. Beyond its raw performance, the 959 introduced innovations like a six-speed manual transmission, a precursor to modern all-wheel-drive systems, and a sophisticated electronic control system that adjusted power distribution in real time. These features, now commonplace in modern supercars, were groundbreaking in the 1980s.
Porsche produced only 337 units of the 959 between 1986 and 1988, including both Komfort and Sport variants. Its limited production, combined with its technological prowess, cemented its status as a collector’s dream. Yet, among these rare machines, one stands alone: the 959 Speedster, a roofless marvel that pushes the boundaries of exclusivity.
The Birth of the 959 Speedster
The Porsche 959 Speedster is not a factory creation but a bespoke masterpiece born from the vision of a single owner and the craftsmanship of a renowned coachbuilder. In 1989, a wealthy Porsche enthusiast commissioned the conversion of a 959 Komfort into an open-top Speedster, a configuration Porsche never officially produced. The project was entrusted to Carrozzeria Pininfarina, the legendary Italian design house responsible for some of the most iconic cars in history, including numerous Ferraris.
The transformation was no small feat. The 959’s complex engineering, including its all-wheel-drive system and lightweight composite body, presented significant challenges for creating a convertible variant. Pininfarina’s artisans meticulously reworked the chassis, reinforcing the structure to maintain rigidity without a fixed roof. The result was a seamless integration of the 959’s original design with a sleek, open-top aesthetic. The car retained its signature Aquamarine Blue paint, a nod to Porsche’s classic color palette, and its interior was updated with bespoke leather upholstery, blending luxury with the car’s performance pedigree.
What makes this 959 Speedster truly unique is its status as a one-off. Unlike other Porsche Speedsters, such as the 911-based models, this car was never intended for production. It exists as a singular expression of creativity and ambition, a testament to the lengths one enthusiast went to realize a dream. The car’s full documentation, including records of its conversion and maintenance, accompanies it to auction, further enhancing its provenance.
Design and Engineering Highlights
The 959 Speedster retains the core attributes that made the original 959 a legend while introducing a daring open-top configuration. Its exterior design is a harmonious blend of the 959’s aerodynamic lines and the timeless appeal of a Speedster. The removal of the roof accentuates the car’s low, wide stance, and the Aquamarine Blue finish shimmers under the light, drawing attention to its flawless curves. The iconic 959 features—pop-up headlights, wide rear fenders, and a subtle rear spoiler—remain intact, preserving the car’s unmistakable silhouette.
Mechanically, the 959 Speedster is identical to the Komfort variant from which it was derived. The twin-turbo flat-six engine delivers the same exhilarating performance, with a 0-60 mph time of approximately 3.6 seconds and a top speed approaching 200 mph. The all-wheel-drive system, with its adjustable torque split, ensures exceptional grip and handling, even in challenging conditions. The car’s adjustable suspension allows drivers to tailor the ride height and damping, a feature that was decades ahead of its time.
Inside, the 959 Speedster offers a bespoke experience. The cabin, trimmed in premium leather, balances sportiness with refinement. The analog gauges, manual gearshift, and minimalist layout evoke the 1980s, while the craftsmanship reflects Pininfarina’s attention to detail. The open-top design amplifies the sensory experience, allowing drivers to hear the turbocharged engine’s distinctive whine and feel the rush of wind at high speeds.
The Auction: A Moment in Automotive History
The upcoming auction in Milan, hosted by RM Sotheby’s, marks a rare opportunity for collectors to acquire a piece of Porsche history. The 959 Speedster’s estimated price range of $1,250,000 to $1,700,000 reflects its rarity and significance. While this figure is substantial, it is not unprecedented for a car of this caliber. In recent years, rare Porsches, particularly those with unique provenance, have commanded multimillion-dollar sums at auction. For example, a 959 Komfort in pristine condition sold for over $2 million in 2023, underscoring the model’s enduring value.
The 959 Speedster’s appeal lies in its uniqueness. As a one-off creation, it is unlikely to ever be replicated. Its combination of Porsche’s engineering, Pininfarina’s design, and the Speedster’s open-top allure makes it a holy grail for collectors. The car’s documented history, matching numbers engine, and pristine condition further enhance its desirability. RM Sotheby’s has positioned the auction as a highlight of its 2025 calendar, expecting fierce bidding from Porsche enthusiasts and investors alike.
The Milan setting adds a layer of prestige to the event. Italy, home to Pininfarina and a hub of automotive design, is a fitting stage for the 959 Speedster’s debut on the auction block. The car’s Italian connection, through its coachbuilt conversion, makes the location all the more symbolic. Collectors from around the world are expected to attend, either in person or via remote bidding, to vie for this once-in-a-lifetime opportunity.
The Cultural and Historical Significance
The Porsche 959 Speedster is more than a car; it is a cultural artifact. The 959 itself was a product of Porsche’s ambition to push boundaries, born during an era when automakers were racing to redefine performance. Its influence can be seen in every modern supercar, from the use of all-wheel drive to the integration of advanced electronics. The Speedster variant takes this legacy a step further, embodying the spirit of individuality and craftsmanship.
In the context of Porsche’s history, the 959 Speedster joins a lineage of iconic open-top models, from the 356 Speedster to the 911 Speedster. Yet, its connection to the 959—a car designed for rally stages and autobahns—sets it apart. It represents a bold reimagining of what a Speedster can be, blending the raw performance of a supercar with the freedom of an open cockpit. This duality makes it a bridge between Porsche’s past and its future, a reminder of the brand’s ability to innovate while honoring its heritage.
The car’s journey to auction also reflects broader trends in the collector car market. In recent years, one-off and bespoke vehicles have surged in popularity, as collectors seek exclusivity in an increasingly homogenized world. The 959 Speedster, with its singular story and impeccable pedigree, is a perfect example of this trend. Its sale will likely set a benchmark for future auctions, signaling the growing value of unique automotive creations.
Why the 959 Speedster Matters Today

Electric vehicles, autonomous driving, and sustainability dominate the conversation, while traditional combustion-engine cars face an uncertain future. Against this backdrop, the 959 Speedster serves as a poignant reminder of a bygone era. Its analog driving experience, mechanical purity, and bespoke craftsmanship offer a counterpoint to the digital age, resonating with enthusiasts who crave authenticity.

The 959, and by extension the Speedster, embodies Porsche’s relentless pursuit of excellence, a ethos that continues to define the company.
For collectors, the 959 Speedster represents the ultimate prize. Its rarity, beauty, and historical significance make it a trophy unlike any other. Whether it finds a home in a private collection or a museum, its story will continue to inspire future generations of car enthusiasts.
