Porsche 908 - The Ultimate Guide

Porsche built approximately 31 Porsche 908s between 1968 and 1971, across several distinct versions and configurations, including 908/01, 908/02, 908/03, and 908/04 (a later modernized concept).

Each variant served a specific racing purpose:

The original 908/01 featured a long-tail body for high-speed tracks like Le Mans.

The 908/02 introduced a lighter, open-cockpit "spyder" design for twisty circuits like the Targa Florio and Nürburgring.

The 908/03 was even more extreme—ultralight and compact, built specifically for tight, technical courses.

The 908/04, created decades later as a tribute and concept, was never a factory race car but rather a modern homage blending retro design and modern tech.

Though production numbers were low, the 908 had an outsized impact in racing, earning numerous victories and playing a pivotal role in Porsche’s climb to prototype racing dominance.

Today, a genuine Porsche 908 can command prices ranging from $4 million to over $7 million, depending on the specific variant, originality, condition, and—most importantly—its racing history.

Cars with documented entries or podium finishes at legendary events like the 24 Hours of Le Mans, Targa Florio, or Nürburgring 1000km tend to reach the higher end of that spectrum, especially rarer versions like the ultra-light 908/03. Due to the car’s low production numbers (around 31 built) and its critical role in Porsche’s prototype racing legacy, the 908 is one of the most coveted vintage Porsche race cars among collectors and historic racing enthusiasts.

Some well-preserved or historically significant examples have exceeded $8 million in private sales or auctions, especially those with connections to iconic drivers or factory-backed teams.

The Porsche 908 was powered by a 3.0-liter flat-eight engine, developed specifically to comply with the new FIA prototype regulations introduced in 1968. Across its various iterations, the engine produced between 350 and 370 horsepower, depending on tuning, configuration, and variant.

This high-revving, air-cooled engine was a masterpiece of lightweight engineering, delivering strong power and excellent reliability—ideal for grueling endurance races like Le Mans and the Nürburgring 1000km. Later variants, such as the ultra-light 908/03, took full advantage of this power in a chassis weighing less than 600 kg (around 1,300 lbs), resulting in exceptional agility and performance on tight, technical circuits.

While the Porsche 908 was primarily known for its 3.0-liter flat-eight engine, there were a few notable variations and experimental configurations over its development that used different engines—though they were limited and not widely used in competition.

In the early 1970s, Porsche began experimenting with turbocharging in endurance prototypes, leading to the development of cars like the 917/10 and 917/30. A turbocharged version of the 908 flat-eight was tested but never widely raced. This experimentation helped pave the way for Porsche’s dominance in turbocharged racing later in the decade.

The Porsche 908/04 is not an original factory-built 908 but a modern tribute car, created by private enthusiasts and engineers decades later. Some of these feature modern turbocharged flat-six engines or other powertrains inspired by the original flat-eight, but they are not official Porsche engines and differ significantly from the factory originals. So, while the 3.0L flat-eight was the definitive and most widely used engine in the Porsche 908, there were experimental and modernized versions that used different engines, primarily for development or tribute purposes. However, none of these alternatives overshadow the original flat-eight’s role in the 908’s racing success and legacy.

The Porsche 908 was one of the most successful and versatile race cars of its era, playing a crucial role in Porsche’s rise to dominance in prototype endurance racing during the late 1960s and early 1970s. Designed to comply with the FIA’s new 3.0-liter prototype regulations, the 908 delivered a string of major victories and became a staple of Porsche’s factory and customer racing efforts.

The 908 debuted in 1968 and quickly proved competitive, scoring class wins and podium finishes at major events like the 24 Hours of Le Mans, where it finished 2nd overall that year. While it didn’t immediately clinch overall victories at Le Mans due to fierce competition from Ford and others, it showed tremendous reliability and consistency—traits that made it invaluable for Porsche's push toward championship success.

In 1969, the 908 truly hit its stride. It achieved 1st overall at the 1000 km of Spa, Nürburgring 1000 km, and the Targa Florio, solidifying its reputation as a formidable endurance contender. Porsche used a mix of 908/02 short-tail Spyders and long-tail coupes, depending on the circuit, giving the team maximum flexibility. The 908 was also a key part of Porsche securing the 1969 International Championship for Makes, a major achievement that proved Porsche could go toe-to-toe with Ferrari, Ford, and Matra.

Perhaps the most legendary variant, the 908/03, debuted in 1970. Designed for tight and twisty circuits, it was incredibly lightweight and agile. It won the 1970 and 1971 Targa Florio and Nürburgring 1000 km, dominating races that favored handling and finesse over brute power. Even after the introduction of the more powerful 917, the 908/03 continued to be used at specific events where its agility made it the better tool for the job.

In total, the 908 collected numerous overall wins, podium finishes, and class victories across the World Sportscar Championship, proving its worth in both factory and privateer hands. Its adaptability, endurance, and engineering excellence made it one of the most important race cars in Porsche history and a vital link between the early prototype racers and the legendary 917.

The Porsche 908 was special because it represented the perfect convergence of engineering precision, racing versatility, and strategic dominance—and it played a pivotal role in elevating Porsche from a class contender to an overall championship powerhouse in endurance racing.

Introduced in 1968, the 908 was Porsche’s answer to new FIA prototype regulations that capped engine size at 3.0 liters, the same limit as Formula 1. To meet this challenge, Porsche developed a lightweight, air-cooled 3.0-liter flat-eight engine, producing around 350–370 horsepower. But what made the 908 truly exceptional wasn’t just the engine—it was how Porsche tailored the car’s design to the specific demands of each circuit. From long-tail coupes for Le Mans to short-tail spyders and ultra-lightweight 908/03s for the Targa Florio and Nürburgring, the 908 wasn’t a single car—it was a platform for dominance, engineered with unmatched flexibility.

Its racing success spoke volumes. The 908 earned overall wins at major endurance races like the Targa Florio, Nürburgring 1000km, and Spa 1000km, and helped Porsche clinch the 1969 and 1970 International Championship for Makes. It became the foundation of Porsche’s strategic approach: choose the right car for the right track, and win through consistency, reliability, and intelligent design—not just brute force.

What makes the 908 especially important is that it bridged eras—it was the direct link between the earlier 906/907 racers and the legendary 917. Without the lessons learned from the 908, Porsche's greatest endurance victories might never have happened. Agile, adaptable, and victorious, the 908 wasn’t just a race car—it was a statement of intent, a turning point that proved Porsche could take on the world and win.
