PORSCHE up to the 917
From the raw, aluminum-clad Porsche 550 Spyder—the audacious “giant killer” that humbled larger machines on the world’s toughest circuits—to the ferocious, flat-12-powered 917 that finally delivered Porsche’s first overall victories at the 24 Hours of Le Mans, this collection traces one of the most remarkable engineering and sporting evolutions in automotive history.
These mid-engined prototypes embodied Ferry Porsche’s relentless pursuit of lightweight agility, innovative aerodynamics, and race-bred technology. Each generation built directly on the lessons of the last: the four-cam flat-four of the 550 gave way to refined spaceframe chassis in the 718 RSK/RS 60, then to the sophisticated flat-eight prototypes of the 907 and 908, culminating in the awe-inspiring 917 that rewrote the rules of endurance racing and dominated Can-Am. Their on-track legacy—class wins at Targa Florio, outright triumphs at Daytona and the Nürburgring, and Le Mans glory—cemented Porsche’s reputation as a manufacturer that punches far above its weight.
Today, that same racing DNA drives an extraordinary surge in the collector market. Authentic, well-provenanced examples from this golden era routinely command multimillion-dollar prices at prestige auctions, with record-breaking sales reflecting their extreme rarity, unmatched historical significance, and enduring cultural cachet—from Steve McQueen’s silver-screen 917 to unrestored 550 survivors with patina. Whether you seek the intimate thrill of a 550 Spyder, the balanced poise of a 718 RSK, the endurance-proven precision of a 908, or the raw power of a 917, these cars represent the purest expression of Porsche’s competitive soul.
Welcome to Porsche Up to the 917—a chronological journey through the machines that transformed a small Stuttgart workshop into a global motorsport legend, and whose auction values continue to reflect their timeless appeal.

550
The Porsche 550 Spyder (including the evolved 550A variant) is a rare, purpose-built mid-engine sports-racing car produced in limited numbers from 1953–1958. Approximately 90 examples of the original 550 (often called RS Spyder or 550/1500 RS) were built, followed by about 40 of the lighter, spaceframe-chassis 550A. These "giant killers" featured aluminum bodies by Wendler, four-cam flat-four engines (typically 1.5 liters, producing 110–135 hp), and exceptional competition pedigrees in events like Le Mans, Sebring, and Nürburgring.
Auction prices for authentic, well-provenanced examples have consistently reached multimillion-dollar levels, driven by extreme rarity, historical significance, originality/patina, matching-numbers components, and racing history. Values vary based on condition (unrestored survivors often command premiums), provenance, and series (550 vs. 550A). The current market benchmark is in the $3–6+ million range, with private sales sometimes higher.

Value Drivers
- Series Differences: Early 550s emphasize raw racing heritage and patina; 550As offer lighter spaceframe construction and refined performance, often appealing to buyers seeking works-car history. Both use similar Wendler aluminum bodies.
- Key Value Factors:
- Originality/Unrestored Condition: Survivors like 550-0090 and 550-0060 command premiums for untouched patina and low mileage.
- Provenance/Racing History: Works entries, famous drivers/owners (e.g., Seinfeld, Carel Godin de Beaufort), or period results (Le Mans, Sebring) add significant value.
- Matching Numbers: Original engine, gearbox, and chassis boost authenticity.
- Documentation: Period photos, correspondence, and continuous history are critical.
- Condition/Rarity: Only ~130 total across series; unrestored or barn-find examples can surprise (though some require work).
- Auction Houses: Bonhams, Gooding & Company, and RM Sotheby's dominate high-end sales, often at prestige events (Amelia Island, Goodwood Revival, Scottsdale, Monterey, Paris).
- Trends: Prices have risen sharply since the early 2010s due to collector demand for 1950s Porsche racing icons. Recent sales (2022–2024) show resilience in the €3–4+ million range despite market fluctuations. Private sales may exceed auctions for exceptional cars.
1955 chassis 550-0060
2016 SOLD for $ 5.3M by Gooding
Porsche had been a company for engineering and development. After war, the founder's son Ferry Porsche creates his brand of sports cars. The first model is the Porsche 356.
Porsche also very soon offers bodies of Spyder type, a wording chosen by the Italian brand Cisitalia with which Ferry Porsche maintains a close cooperation.
Porsche continues to innovate. The engine type 547 is robust and reliable, with a new design of the camshaft. Unfortunately, it is very difficult to assemble and is not compatible with the 356 chassis. The Porsche 550 with a 547 engine, created in 1953, is an important step in the product line of the brand.
Released in 1953, the Porsche 550 Spyder is efficient and agile with its flat four 1.5 liter engine. Porsche had made a good choice because this category of small volumes is undisturbed by the changes in the rules that follow the 1955 disaster at Le Mans.
The 550 has all the features to become a fetish model. On September 30, 1955, James Dean tries his brand new Porsche. He did not want any rival in his way, and he dies by hitting at full speed a branching Ford.

The increase of power of the racing cars in the first half of the 1950s seems inevitable and is indeed somewhat frightening when we consider in rear view the disasters at Le Mans and in the Mille Miglia.
Amidst the bolides by Ferrari, Mercedes-Benz, Jaguar, Aston Martin and Maserati, Porsche has the merit of finding innovative solutions by promoting small cars with low displacement volumes in a brilliant technology that reaches the extreme limit of feasibility.
The 356 had opened to Porsche the market of the sports cars. The 550 Spyder is their first experience of a car designed for the race. From its first competition in 1953, this model with a 1.5 liter engine built its reputation as a killer of giants.
The 550 is a victim of its own success and many units were damaged. One of them, made in 1955, is in an exceptional condition close to a time capsule.
Its early history is not known. Discovered by an amateur in Massachusetts in the early 1960s within a lot of second hand cars, it has preserved up to now its original paint and upholstery, and of course kept also its matching number equipment. It is one of very few examples by which an amateur can still retrieve the pleasure of driving an authentic Porsche Spyder of the 1950s.
This wonder was only 16,000 km from new when it was acquired in 2007 by Jerry Seinfeld. The comedian, also known for his great enthusiast in driving old Porsche cars, respected and maintained its perfect condition, adding only 800 Km to its odometer. Now he chooses to part ways from it. This car was sold for $ 5.3M by Gooding on March 11, 2016, lot 034.

1956 550 RS, chassis 550-0090
2016 SOLD for £ 4.6M by Bonhams
When the spyder superseded the speedster, Porsche created the glamour car of the 1950s. Taking advantage of the complex classification of the endurance competitions, the German brand demonstrates the unprecedented effectiveness of its model 550 RS with its low displacement of 1,5 liters.
This small speedy car does not intimidate the wealthy individuals and perfectly meets the desires of the young 'rebel' Americans after the war. It is no coincidence that James Dean trades in 1955 his Porsche 356 speedster for a 550 spyder. Shortly afterward Chinetti will force Ferrari to create the California Spider targeting a similar clientele.
These small Porsche cars were pushed up to their limits by their owners eager for new sensations and new glamorous conquests. Such vehicles kept in their original condition are scarce and precious.
According to these criteria the 550 RS offered by Bonhams on September 10, 2016 is considered as perfect in the press release issued by the auction house. Not enjoying the miracle of a time capsule, it was used by its owners but careful services have prevented any restoration.
This car made in 1956 is one of the last 550 before this model was replaced by the 550A. It was coachworked by Wendler as a two seater spyder. It was sold for £ 4.6M, lot 140.
The competition remained essential to promote such a product line. Another 550 also made in 1956 and coachworked in single seater was sold for $ 3.75M before fees by Mecum on August 17, 2013.

1958 chassis 550A-0145
2018 SOLD for $ 5.2M by Bonhams
Continuous improvement is a must for competition. In 1956 the 550A Spyder gets a lighter and more rigid frame, with a weight distribution carefully redesigned to improve the stability. It has a reputation of being very pleasant to drive.
Porsche built four prototype coupes of the 550A, specially designed with a newly patented streamlined roof. They followed with stiffness improvement and reduced weight the two special 550 RS which finished first and second in class and 15th and 16th overall at the 1953 Le Mans 24.
Driven by Maglioli, the first 1956 example won overall the Targa Florio ahead of larger displacement competitors.
Forty 550A are built. The last but one is sold in April 1958 to Carel De Beaufort who uses it in competition in that year. In May De Beaufort dares to engage his little spyder in the Dutch Grand Prix of Formula One at Zandvoort. He finishes in last position six laps behind the winner. Meanwhile Porsche had developed the 718 that De Beaufort will now more logically use in Formula One. In a great loyalty to the brand, De Beaufort almost only used Porsche cars from 1957 to his death in 1964.
That spyder also had a racing history in period in Le Mans and Nürburgring. It passed at Gooding on August 20, 2016. It had been introduced in a video. It was sold for $ 5.2M by Bonhams on January 18, 2018, lot 44. Please watch the video prepared by Bonhams.

Porsche 550A. Compare Chassis 0116, unsold by RM Sotheby's on April 25, 2026, lot 165, vs. Chassis 0145, sold by Bonhams on January 18, 2018, lot 44.
Here's a detailed comparison of two rare Porsche 550A Spyder examples from the ultra-limited production run (approximately 40–46 units built between 1956–1958). These cars represent the evolved "A" variant of Porsche's pioneering 550 series, featuring a lighter, stiffer spaceframe chassis (replacing the earlier ladder frame), refined low-pivot swing-axle rear suspension, and the potent 1.5-liter DOHC flat-four "Fuhrmann" four-cam engine. Both are coachbuilt by Wendler and embody the "giant killer" ethos that helped establish Porsche's racing reputation in the 1950s.

Both are coachbuilt by Wendler and embody the "giant killer" ethos that helped establish Porsche's racing reputation in the 1950s.
Key Specifications and Context
- Shared Traits: Both are 1957–1958 550A Spyders with matching-numbers potential (engine original to chassis in 0145; likely similar for 0116), drum brakes, lightweight aluminum bodywork, and exceptional period competition capability in SCCA, FIA, and endurance events. Production was tiny, making any authentic 550A highly desirable among collectors.
- Chassis 550A-0116 (1957, Lot 0165 / or similar at RM Sotheby's Monaco, April 25, 2026):
- Delivered new to prominent California racer Jack McAfee (with Stan Sugarman).
- Competed extensively in American SCCA events (1957–1962), scoring class and outright wins at circuits like Laguna Seca, Riverside (including a victory), and Pomona.
- Known as a "Giant Killer" in U.S. sports car racing.
- Later ownership spanned multiple continents (U.S., South Africa, Japan, Germany); acquired by Japanese collector Hui Takahara in 1993, then underwent a complete overhaul in Germany.
- Recently completed an exhaustive six-year restoration (invoices exceeding £307,000); described as "box-fresh" with minimal post-restoration mileage (e.g., only an initial test drive in some reports). Concours-ready, with awards including Best in Class at events like The Amelia (post-war race cars pre-1965).
- Chassis 550A-0145 (1958, sold Bonhams Scottsdale, January 18, 2018, Lot 44):
- One of the final 550As built (second-to-last or penultimate example); benefited from all late-production refinements.
- Porsche Works entrant from new, with a factory-backed competition history in European FIA World Sportscar Championship events.
- Key results: 2nd in class and 5th overall at the 1958 24 Hours of Le Mans (driven by owner/racer Carel Godin de Beaufort); class winner at the Nürburgring 1000 km; class winner at the 12 Hours of Reims; class winner at Zandvoort NAV Race; class winner at the Dutch Grand Prix (believed to be the only 550A to compete in a Grand Prix).
- Later participated in 10 editions of the Mille Miglia Storica.
- Engine No. P90127 original to the chassis; highly documented with a detailed 2013 inspection report by specialist Andy Prill.
- 0116: Strong privateer/U.S. club racing pedigree focused on SCCA success against larger-displacement rivals. Tied to American motorsport icon Jack McAfee. No major European factory-backed endurance outings, but consistent wins in a competitive domestic scene. Post-racing life involved global ownership and a thorough restoration.
- 0145: Superior international factory-level provenance. As a Porsche Works car, it competed in prestigious world championship events with factory support. Its Le Mans result (top-5 overall in a small 1.5L car) and multiple class wins in major endurance races give it deeper historical significance in Porsche's motorsport heritage. Also unique as a GP competitor among 550As.
Auction History and Market Performance
- 0116: Upcoming at RM Sotheby's Monaco 2026 (estimate €3,500,000 – €3,800,000, roughly $3.8M–$4.1M USD at current rates). No recent public sale noted; prior ownership transitions were private. The fresh, high-quality restoration and "box-fresh" condition position it as turnkey for vintage racing or shows. Monaco timing (during Historique weekend) should attract strong European and international bidding.
- 0145: Sold for $5,170,000 (including premium) at Bonhams Scottsdale 2018 (estimate $4.5M–$5.5M). It was a headline car and topped the sale. Previously offered (unsold) at Gooding & Company Pebble Beach 2016 with a $5M–$6M estimate. The result reflected strong demand for its works/Le Mans history at the time.
- 0145 (at 2018 sale): Well-maintained with original engine; visually preserved but used in historic events (Mille Miglia). Detailed specialist report supported its authenticity.
- 0116 (2026 offering): Exceptional post-restoration condition — exhaustive work, low mileage since, and concours-proven. Likely matching or highly original components given the care taken. Ready for immediate use without further investment.
- Strongest Racing/Provenance: 0145 wins for its Porsche Works status, Le Mans 5th overall, multiple international class victories, and GP participation — a true factory hero with deeper ties to Porsche's global legacy.
- Restoration/Condition: 0116 has the edge with its recent, costly, "box-fresh" restoration and concours success; it's arguably more immediately presentable and drivable.
- Driver/Story Appeal: 0145 links to Carel Godin de Beaufort and factory efforts; 0116 to Jack McAfee and vibrant U.S. SCCA racing.
- Market/Investment: 0145 realized a higher price in 2018 ($5.17M vs. 0116's €3.5–3.8M estimate). The latter may represent relative value or appeal to buyers seeking a turnkey example, though final 2026 results will depend on bidder interest in Monaco. Both are among the most significant surviving 550As.
- Desirability: These are pinnacle 1950s Porsche racers — lightweight, agile, and historically important. 0145 suits collectors prioritizing factory provenance and endurance glory; 0116 appeals for its American racing wins, pristine restoration, and versatility in vintage events/concours.
718
The Porsche 718 RSK (and closely related RS 60/RS 61 variants) represents the evolution of Porsche's mid-engined Spyder racing cars from the 550 series. Produced in very limited numbers (around 34–35 customer + works RSKs from 1957–1959, followed by RS 60/61 developments into 1962), these cars featured a lightweight spaceframe chassis, independent rear suspension, and the potent Type 547 four-cam flat-four engine (typically 1.5–1.7 liters, 140–160+ hp). They achieved major successes in sports car racing, including class wins and outright victories at events like Sebring, Targa Florio, Nürburgring, and Le Mans. Bodies were hand-formed aluminum by Wendler.
Only a handful of authentic examples reach the open market, with values driven by rarity, period racing history (especially works entries), matching-numbers components, originality, and provenance. Auction results typically fall in the $2–4+ million range, with exceptional Werks or heavily documented cars exceeding $4 million. The broader 718 Spyder family (including RS 60) has seen peaks above $5 million.

The broader 718 Spyder family (including RS 60) has seen peaks above $5 million.
Value Drivers
- Rarity & Variants: ~34–35 pure RSKs; even fewer true Werks cars. RS 60/61 versions feature refined aerodynamics and longer wheelbases in some cases. Center-seat configurations (rare, ~4–6 known) add uniqueness but can complicate sales.
- Key Factors:
- Racing Pedigree: Works entries or notable privateer results (e.g., Targa Florio, Sebring, Le Mans class wins) significantly boost value.
- Matching Numbers & Originality: Original engine, gearbox, and Wendler body command premiums; careful restorations preserving patina or history are preferred.
- Provenance: Continuous documentation, famous drivers/owners (e.g., Bob Holbert, Ed Hugus), and low owner count enhance appeal.
- Condition: Well-sorted, race-ready examples or unrestored survivors with period correctness outperform heavily modified ones.
- Market Trends: Prices rose sharply in the 2010s and have held firm in the $2.5–4+ million band for strong cars, with peaks for elite examples. Gooding & Company, RM Sotheby's, and Bonhams handle most high-end sales, often at flagship events (Pebble Beach, Monterey, Amelia Island). The 718 Spyder lineage benefits from broader 1950s–60s Porsche racing nostalgia, though supply remains extremely limited. Replicas trade at a fraction of the price.
- Related Models: The 550 Spyder (predecessor) and later 718 RS 61 often appear in similar contexts; values overlap but RSK/RS 60 command attention for their transitional engineering advances.
1959 718 RSK Spyder, chassis 718-006
2022 SOLD for $ 4.3M by RM Sotheby's
The 1950s saw the supremacy of the spyder body in endurance and hill climbing races. For winning, the brands invest in technological developments which are disturbed by the incessant and often essential changes in the regulation of racing.
During this period, Porsche became a formidable competitor against Ferrari and Jaguar. At the end of the decade, the Porsche 718 RSK Spyder is a culmination of their efforts. Bodied by Wendler, it is a small car, low and streamlined, with a light weight and high rigidity and stability in the follow of the 550.
34 cars were produced in this model, including 10 factory team alloy Spyders. An early RSK finished 1st in class and 3rd overall at the 1958 Le Mans 24.
One of these 718 RSK Werks Spyder got significant competition results in its 1959 factory team season, driven by von Trips, Bonnier, Herrmann, Maglioli, Barth, and MacAfee. It finished first in class at Sebring 12 hours and Nürburgring 1000 km and entered several hillclimbs. In 1960 new FIA rules supported the success in Europe of the improved RS 60 version and that Werks car was sold to a US privateer.
This car made in 1959 had also been the prototype for a modified rear suspension. Its original engine was damaged beyond repair in the 1970s. Polished to mirror like finish, the car had once been nicknamed the Shining Spyder.
Now extensively restored and re-painted, it was sold for $ 4.3M by RM Sotheby's on August 20, 2022, lot 344.
A 718 RSK made in 1959 was sold new to a US privateer. A US amateur then raced it in SCCA and USAC events from 1960 to 1963. It had been sold for $ 3.74M by Gooding in August 2018, lot 128.
It later had an award winning restoration by Rare Drive Inc in its 1959 Le Mans configuration with its Lucybelle private livery. It is illustrated in a pre sale press release. by Gooding before it passed on August 20, 2022, lot 137. It is introduced and driven by David Gooding with its detailed restoration narrated by the Rare Drive restorer in the video shared by the Gooding. It passed at Broad Arrow on March 2, 2024, lot 239. Please watch the video shared by Broad Arrow.
Also built in 1959, another example was sold by Gooding for $ 3.13M in January 19, 2013, lot 112.This car has retained its original engine and body. It also had a fair racing history in the hands of its first owner, a private driver.

Porsche was becoming a formidable competitor against Ferrari and Jaguar. From 1958 the 1.5/1.6 liter 718 RSK Spyder is the culmination of their efforts. Bodied by Wendler Karosserie, it is a small car, low and streamlined, with a light weight and high rigidity and stability in the follow of the 550. 34 cars were produced in this model, including 10 factory team alloy Spyders. An early RSK finished 1st in class and 3rd overall at the 1958 Le Mans 24.
One of these 718 RSK Werks Spyder got significant competition results in its 1959 factory team season, driven by von Trips, Bonnier, Herrmann, Maglioli, Barth, and MacAfee. It finished first in class at Sebring 12 hours and Nürburgring 1000 km and entered several hillclimbs. In 1960 new FIA rules supported the success in Europe of the improved RS 60 version and that Werks car was sold to a US privateer.
This car made in 1959 had also been the prototype for a modified rear suspension. Its original engine was damaged beyond repair in the 1970s. Polished to mirror like finish, the car had once been nicknamed the Shining Spyder. Now extensively restored and re-painted, it was sold for $ 4.3M by RM Sotheby's on August 20, 2022, lot 344.
Developed in 1959 for Formula 2 with a 1.5 liter engine, the 718/2 becomes competitive in Formula 1 thanks to a further limitation of engine displacement in this category.
For endurance, the 718 is much modified in 1960 including a larger cockpit matching new FIA rules, improved brakes, smaller wheels and a larger wheelbase. That 718 RS 60 spyder is built in about 18 units of which 4 are attributed for the factory team.
Porsche want their cars to win with their own team. The RS 60 works cars receive exclusive aerodynamic improvements. They are driven by champions including Graham Hill, Stirling Moss and Jo Bonnier.
The RS 60 and its follower RS 61 are light, well balanced and handy to drive, well suited to difficult roads. It is really competitive against more powerful entrants.
For Le Mans 1960 two RS 60 works cars are equipped with 1,606 cc engines. In 1961 one of them receives a 1,678 cc engine for Sebring and for the Nürburgring. Meanwhile it amazingly performed at the Targa Florio with a 2-liter engine : driven by Stirling Moss, it was leading at the entrance of the last lap but had to stop a few kilometers before the finish line. This car is unique in its kind : it was the only RS 60 that could accommodate a 2-liter engine, thanks to a stiffening of the chassis.
It was sold for $ 5.4M by Gooding on August 16, 2015. After being restored, it was sold for $ 5.1M by RM Sotheby's on August 17, 2019, lot 348.
Delivered in the USA in 1960, the RS 60 718-060 had been extensively used in competition over four seasons, achieving 12 class wins in 17 races, finishing all of them thanks to the uncommon careful drive of its first owner who was a car dealer in Milwaukee. Never crashed or damaged, this car retains its original aluminum body by Wendler, and its engine is in matching numbers. It was sold for $ 3.5M by RM Sotheby's on August 15, 2025, lot 143.

907 and 908
The Porsche 907 (1967–1968) and 908 (1968–1971, in variants like 908/02 Spyder, 908/03, and coupe/short-tail/long-tail) were critical prototypes in Porsche's endurance racing evolution. The 907 featured a 2.0–2.2L flat-eight engine (up to ~280 hp) and served as a bridge from the 910/906 era, delivering Porsche's first 24-hour overall win (Daytona 1968). Only about 21 examples were built, in short-tail (K) and long-tail (LH) configurations.
The 908 advanced this with a 3.0L flat-eight (~350 hp), lighter construction, and variants optimized for different circuits (e.g., nimble 908/03 Spyders for Targa Florio/Nürburgring, short-tail coupes). Around 30–35 chassis were produced across series, including works and customer cars. These models achieved numerous class and outright victories (Targa Florio, Nürburgring 1000 km, etc.) and paved the way for the 917. Bodies were lightweight fiberglass or aluminum; values today emphasize works history, matching components, and period documentation.
Auction appearances are extremely rare due to low production and collector retention. Prices for authentic examples typically range $3–5+ million, with premiums for documented racing pedigrees.

Value Drivers
- Rarity & Variants: 907 limited to ~21 total (short vs. long tail affects aero/ suitability for specific races). 908 variants include coupes (short/long tail), Spyders (908/02 "Flunder" lightweight), and hillclimb/Targa-optimized 908/03. Works cars or those with famous drivers (Elford, Siffert, Herrmann, Rodriguez, etc.) command the strongest premiums.
- Key Factors:
- Racing Pedigree: Daytona, Targa Florio, Le Mans, Nürburgring, or Sebring results add massive value; works entries outperform privateer cars.
- Originality & Matching Numbers: Factory engines, gearboxes, and bodywork; minimal modifications or careful period-correct restorations preferred.
- Provenance/Documentation: Continuous history, factory records, and photos are essential; long-term ownership (e.g., decades with one collector) boosts appeal.
- Condition: Race-ready or concours-level examples; patina on genuine survivors can be a plus.
- Market Trends: These 1960s–70s prototypes benefit from Porsche's prototype racing golden era nostalgia, overlapping with 917/550/718 interest. Prices have climbed since the 2010s, with 907 setting records in the $3.6–4.8M+ band and 908s holding $3.5–4.2M for top examples. Supply is minuscule; many change hands privately. Auction houses like Gooding & Company, RM Sotheby's, Artcurial, and Broad Arrow (Hagerty) dominate, often at flagship events (Amelia Island, Monterey, Rétromobile, Paris).
- Related Notes: Replicas or heavily modified cars trade far lower. Values overlap with contemporary prototypes but emphasize endurance success over outright power. For full chassis histories, specialist resources like racing databases or Porsche archives are ideal, as new details emerge with restorations or sales.
1968 chassis 907-031
2022 SOLD for € 4.4M by Artcurial
Since 1964, the Ford GT40 is the wonder of the circuits. Beautiful and effective, it still looks like a road car. In 1967, Porsche wants to become the great rival of Ford and Ferrari in endurance races.
Cars of that time have the required robustness for competitions of 12 or 24 hours or 1000 km. Porsche understands that the advantage must now come through the top speed in straight lines. Of course, the target of the German brand is Le Mans with its famous Mulsanne straight.
With the Porsche 907, the optimization is performed by the aerodynamic shape of the coachwork with lower body and long tail. This car inaugurates these new shapes which, beyond the oil crisis, lead to supercars. The new model reaches 300 km/h.
The 2.2 litres 8 cylinder engine is ready in 1968, replacing the original 2 litres 6 cylinders of the model. The new model 908 has the same 8 cylinder engine bored out to 3 litres. The fabulous career of Porsche in endurance racing has begun. As early as 1969, the Porsche 917 is released.
The penultimate 907 from 1968 was sold for € 4.4M by Artcurial on March 18, 2022, lot 203. Please watch the video shared by the auction house. This car was raced in many competitions including three times Le Mans 24, from 1970 to 1972, and the Nürburgring 1000 km in 1968 as an ex works car.

1969 chassis 908/02-06
2022 SOLD for $ 4.2M by Gooding
Porsche had a long tradition of entering small and light cars in racing competition. The brand got its advantage by the complexity of its small engines and the care to aerodynamics in the bodywork.
The 2.2 litres 8 cylinder engine is ready in 1968, replacing the original 2 litres 6 cylinders of the model. The new model 908 has the same 8 cylinder engine bored out to 3 litres.
Like Ferrari in the 1950s, Porsche appreciates that different competition profiles require various technical solutions. Developed in parallel in 1968 and 1969, the powerful 917 with a 4.5 liter engine and the small 908 do not have the same targets.
The 917 targets Le Mans. The 908 manages to be maneuverable on twisty circuits and winding roads such as Nürburgring and Targa Florio. The major challenge is the stability for the 917 and the light weight for the 908.
The first 908's had been coupes. The 908/02 version, released in 1969, is a spyder, lighter than the previous 908 coupe, weighing 600 kg in its aluminum frame. Its flattened body opens the style of extreme minimalism in the shape : the optimization of the aerodynamics leaves no place for an aesthetic initiative excepted for garish colors. It got the nickname Flunder, a flat fish.
With a shorter chassis the 908/03 introduced in 1970 weighs 500 kg. It includes the ultimate subtlety of decentering the weights to the right side for a greater efficiency in the closed circuits of Nürburgring and Targa Florio. Vertical fins are added to the rear in 1971.
The 908 wins the 1000 Km Nürburgring every year from 1968 to 1971, breaking the record of 6H 54 obtained in the previous year by a Porsche 910. The progression rewards the efforts of the designers : 6H 34 by a 908 in 1968, 6H 11 by a 908/02 in 1969, 6H 05 by a 908/03 in 1970 and 5H 51 in 1971 by a 908/03 piloted by a private team.
A 908/02 made in 1969 as a works car and acquired by a privateer after a few races was sold for $ 4.2M by Gooding on August 19, 2022, lot 44. It is illustrated in the pre sale press release. Please watch the video shared by the auction house. The car is accompanied with its previous Flunder body and its engine has been rebuilt. It remains otherwise a highly original example with no accident in its six year racing career.
The short tail K version (Kurz Heck) is steady but too heavy while the LH (Lang Heck) has a better top speed. The pilots went to prefer the LH. In 1970, the chassis 5 of the 1969-titled Porsche 908/02 Flunder is modified into a Lang Heck. In this configuration, it gets a fair history in endurance racing and participates in some running sequences in the film Le Mans.
This 908/02 Flunder LH prototype has been restored to its 1970 Martini team Le Mans-24 longtail appearance with which it had finished 1st in class and 3rd overall. It was sold for £ 2.2M by Bonhams on November 30, 2014, lot 23. Please watch the video shared by Broad Arrow before it passed on April 27, 2024, lot 145.

917
The Porsche 917 (1969–1971, with later Can-Am derivatives) is one of the most legendary and dominant sports prototypes ever built. Porsche produced approximately 59 chassis to meet homologation rules (25 initial cars, plus evolutions), including short-tail K (Kurz) coupes, long-tail LH models, and a handful of Spyders. Powered by a 4.5–5.0L flat-12 (up to 630+ hp naturally aspirated; turbo variants exceeded 1,000 hp), the 917 secured Porsche's first overall Le Mans wins (1970 and 1971), numerous endurance victories (Daytona, Spa, Brands Hatch, etc.), and Can-Am dominance. Iconic liveries include Gulf, Salzburg (red/white), and Martini. Bodies were lightweight fiberglass or aluminum; values today hinge on provenance, matching components, works history, and originality.
Genuine 917s rarely appear at auction due to extreme rarity and collector retention. Public sales are exceptional events, often at flagship venues (Pebble Beach/Monterey, Amelia Island). Prices for top examples have reached eight figures, with film/history connections (e.g., Steve McQueen's Le Mans) driving premiums. The 917/30 Can-Am Spyder variant (only ~6 built, ultra-powerful turbo) has also set records in its class.
Chassis 917-022 (1970 917K, ex-Solar Productions Le Mans hero car): Owned by Jerry Seinfeld since ~2001–2002. Offered at Mecum Kissimmee, January 2025. Bidding reached $25 million (a new potential record), but did not sell (reserve not met). Seinfeld later confirmed a private sale in the ~$25M range. This Gulf-liveried car was McQueen's primary on-screen vehicle and personally signed by him; restored with full engine rebuild. Previously sold for $1.32 million at RM Sotheby's Monterey in 2000.

- Variants: 917K (short-tail, most common and successful in mixed conditions); 917LH (long-tail, high-speed aero for Le Mans); 917/10 and 917/30 (turbo Can-Am monsters). Chassis numbering can be complex due to repairs/re-stamping (e.g., some JW cars shared or transferred numbers).
- Key Factors:
- Racing Pedigree: Works entries, Le Mans participation/wins, or famous drivers (Rodriguez, Siffert, Elford, Bell, McQueen connection) add massive premiums.
- Provenance & Documentation: Film history (Le Mans), continuous ownership chain, factory records, and period photos are critical.
- Originality/Matching: Original engine, gearbox, body; careful restorations (vs. heavy modification) preferred. Patina on survivors can enhance appeal.
- Condition: Race-ready or concours-level; turbo Can-Am cars prized for raw power despite limited "road" use.
- Market Trends: Prices exploded in the 2010s with collector interest in 1960s–70s prototypes. The 2017 sale marked a milestone; 2025 bidding shows continued upward pressure for iconic examples. Supply is tiny—most change hands privately. Auction houses like Gooding & Company, RM Sotheby's, and Mecum handle the elite sales, often during Monterey or Amelia weeks. Replicas (even high-quality ones) sell for a fraction.
- Related Notes: Values overlap with contemporaries like the Ferrari 512 or Lola T70 but benefit from Porsche's Le Mans dominance and cultural cachet (e.g., Gulf livery). For full chassis histories, resources like Wikipedia's detailed table or specialist registries (e.g., stuttcars.com) are excellent.
1970 917K, chassis 917-024
2017 SOLD for $ 14M by Gooding
Porsche had never won the 24 hours of Le Mans. A change in regulations announced after the 1968 season by the ACO for the two classes 3 liters and 5 liters is seized as an opportunity. Porsche creates in parallel the models 908 and 917.
The rule for the 5 liter homologation requires that the model is produced in 25 identical units. Porsche's motivation is so intense that they line up their twenty-five 917 in the yard of the factory as early as April 1969. Success is still questionable because the 917 is very difficult to drive. None of them finished the 24 hours of Le Mans 1969 and a driver died during that race.
Porsche immediately conceived the necessary improvements, resulting in two variants of the chassis for each of the two models : K for Kurz Heck and LH for Lang Heck. The short variant is faster in top speed but less stable. Many drivers will prefer the LH.
On August 18, 2017, Gooding sold for $ 14M a historically important 917K, lot 44. Please watch the video shared by Gooding.
This car assembled in 1970 was immediately entered in the training and test sessions at Le Mans, Nürburgring and Ehra-Lessien in April and May, demonstrating the exceptional speed achieved by the 917K model.
It is purchased in June 1970 by Jo Siffert who does not use it in competition but leases it for the preparation of the film Le Mans. It is one of three 917K starring in this movie for which they also served as camera cars for shooting at full speed. This 917K was Siffert's favorite car and led his funeral procession in October 1971.
The car was found 30 years later in a Parisian suburb, covered with dust but untouched except for the absence of the engine. The next owner bought an original engine from the same series. The complete restoration was supervised by a former Porsche engineer who still had access to the factory archives of the 917 program.

The Le Mans movie was produced by Steve McQueen's company Solar Productions. It is the most authentic depictions of motorsport ever captured. Another involved production company had prevented the actor to participate to the actual event in June 1970, due to the risk of a severe accident.
The plot places his character, driver Michael Delaney, behind the wheel of multiple Porsches over the course of the simulated race. The film was released in 1971.
One of these cars had been built by Porsche in 1969 for the FIA homologation of the 917 and converted to short tail specification 917K by the factory in April 1970.
That example was purchased new by McQueen and Solar and extensively used in the race sequences. Camera mounts and brackets were added. He departed from it after the movie. Afterward the 917K competed in and won off-screen races.
Reestablished in its blue and orange Gulf Oil livery of the movie and submitted in 2024 to a rebuild of its mechanical components and frame, it passed at Mecum on January 18, 2025, lot S237, from the collection of the Porsche-loving comedian Jerry Seinfeld. The V-12 engine is still in matching numbers. Please watch the video shared by the auction house.
Robb Report reported that Mr Seinfeld sold privately the Porsche after the Mecum auction for a price in the region of $ 25M.

1972 chassis 917/10-003
2012 SOLD for $ 5.8M by Mecum
In the early 1970s, the cars competing in endurance racing change their look and increase their speed. The development of the Porsche 917 in Spyder bodywork is a great success, both in terms of engineering and sport.
In 1972, Porsche subcontracted to Penske Racing the participation in the competitions. Their goal to dominate the prestigious series of events known as the Can-Am (Canadian American Challenge Cup) met a total success.
Driven alternately by the two Penske drivers, George Follmer and Mark Donohue, this serial number 917/10-003 actually won in 1972 no fewer than five of nine races counted for the Can-Am which was the best track record of the Porsche 917 model.

Driven alternately by the two Penske drivers, George Follmer and Mark Donohue, this serial number 917/10-003 actually won in 1972 no fewer than five of nine races counted for the Can-Am which was the best track record of the Porsche 917 model. It was sold for $ 5.8M by Mecum on August 18, 2012. Please watch the video shared by the auction house.
1973 chassis 917/30-004
2012 SOLD for $ 4.4M by Gooding
Porsche had dominated the Can-Am in 1972 with the 917/10. Its engineers did even better in 1973 : the Porsche 917/30 Can-Am Spyder was later elected by a committee of experts as the greatest racing car of all time. Its participation to competition was provided by the drivers of the Penske team including Mark Donohue.
With its 5.4-liter engine, 917/30 has an unsurpassed power. Compared to the 917/10, its aerodynamics is improved and a clever system of temporary acceleration raising up to 1500 bph enables to instantly leave any competitor behind.
This ultimate model of motor racing is indeed extremely rare despite its dominant performance : only six chassis were built.
001 is a prototype that had ensured the transition from 917/10 to 917/30. All feats in competition including the speed record of 355 km/h in closed circuit were achieved either by 002 or (mostly) by 003. Both are currently owned by Porsche but 002 was badly damaged in a crash at Watkins Glen.
004 was originally intended for the Penske team but the uninterrupted performance of 002 and 003 did not appeal for a spare unit. No longer needed in 1974 due to the fuel limitation imposed from the oil crisis, it is bought, admired and exhibited by the Porsche importer in Australia without entering a race.
Carefully maintained by its successive collectors and repainted in the livery of Sunoco which had been the main sponsor of the Penske team, 004 was sold by Gooding for $ 4.4M on March 9, 2012 and for $ 3M on March 11, 2016, lot 044.
The overwhelming success of the Porsche 917 had killed the suspense in the Can-Am events. This is not the only reason for the ephemeral career of the 917 : the oil crisis also forced the organizers of car racings to cut the costs.
005 and 006 have been much later assembled with smaller engines, 5 and 4.5 liters respectively.
