Built as a Homologation-Special for Group 4 The Porsche 906 was developed in 1966 to compete in FIA Group 4 sports car racing, with 50 units produced to meet the homologation requirements — allowing it to race both as a prototype and GT.
Lightweight Fiberglass Body Over a Steel Space Frame The bodywork was made of fiberglass to reduce weight, and it sat on a tubular steel space frame, giving the 906 a curb weight of just 580 kg (1,280 lbs) — featherlight for its class.
Powered by a 2.0L Flat-Six Engine The standard 906 Carrera 6 featured a 2.0-liter air-cooled flat-six, producing around 210 horsepower, derived from the engine used in the 911R, but tuned for racing.
Top Speed of Over 280 km/h (174 mph) Thanks to its sleek aerodynamics and low weight, the 906 could hit over 280 km/h, making it one of the fastest two-liter race cars of its time.
Designed Under Ferdinand Piëch’s Leadership The 906 was one of the first cars developed under Ferdinand Piëch, who would later become a key figure in the Volkswagen Group. His influence pushed Porsche toward serious racing innovation.
Featured Gullwing-Style Doors and Clear Engine Cover The Carrera 6 had gullwing-style plexiglass doors and a clear plastic rear engine cover, allowing spectators and drivers to view the engine — a unique and futuristic touch.
Successful in Endurance Racing The 906 took class wins at the 24 Hours of Le Mans, Daytona, Sebring, and Targa Florio, often outperforming much more powerful rivals due to its agility and reliability.
Some Versions Equipped with Fuel Injection or Flat-8 Engines While most 906s ran with carbureted flat-sixes, a few were fitted with fuel-injected engines or even Porsche’s flat-8 F1-derived engines, turning them into full-blown prototypes.
Driver-Focused, Spartan Interior The 906’s interior was purely functional, with racing harnesses, minimal gauges, and a single seat in most variants — everything focused on lightness and control.
Paved the Way for Porsche’s Prototype Dominance The 906 laid the groundwork for the 917 and 908, and is now considered a milestone car in Porsche’s racing evolution, blending production-based components with advanced engineering.

The Porsche 906 Carrera 6 (1966–1967) is one of the most coveted racing Porsches of all time—a lightweight, mid-engine prototype that dominated its class at Le Mans, the Targa Florio, and beyond. With only ~50 units built, it’s a seven-figure masterpiece.
Here’s the latest market insight (mid-2024):
Current Value Estimate (EU & Global Market):
€3,500,000 – €6,000,000+ Lower end: Non-continuous racing history, restored, or missing original parts. Upper end: Factory team provenance (e.g., Le Mans/Targa Florio participants), matching-numbers engine, or ex-works cars.
Auction Records:
2015 (Gooding & Co.): $4.84M (~€4.2M) for a Targa Florio class-winner.
2023 Private Sales: Rumored €5M+ for pristine, documented examples.
Why So Expensive?
✔ Rarity: Only ~50 built (street-legal "LH" versions are even rarer). ✔ Racing Pedigree: Beat Ferrari Dinos in the 1966 World Sportscar Championship. ✔ Design: Fiberglass body over tubular chassis—direct predecessor to the 907/908. ✔ Investment Grade: Tracks alongside Ferrari 250 LM and Jaguar D-Type in value growth.
Key Price Factors:
Provenance: Works team cars (e.g., #906-143, 2nd at ’66 Targa Florio) command €1M+ premiums.
Originality: Matching-numbers Type 901/20 flat-six (220hp) is critical.
Condition: Unrestored, patina-rich survivors > heavily restored examples.
History: Documentation (FIA papers, period photos) is essential.
Where to Buy?
High-End Auctions: RM Sotheby’s, Gooding & Company, Bonhams.
Private Brokers: Girardo & Co., DK Engineering, Canepa.
Porsche Specialist: Maxted-Page (UK) or Jürgen Alzen Motorsport (DE).
Market Trend:
Explosive Growth: Prices have tripled since 2010 (€1.5M → €5M+).
Future Outlook: As Porsche’s racing golden age gains prestige, the 906 is a blue-chip asset.
Fun Fact: The street-legal 906 "LH" (Langheck) had a long-tail body and sold for €6.8M in a 2021 private sale—one of the most valuable Porsches ever.
