The Story Behind the Porsche 917

Porsche built the 917 because of a rule change in sports car racing. In the late 1960s, the governing bodies changed the regulations for Group 5 sports prototypes. The new rules favored cars with larger engines. Porsche saw an opportunity. They needed a car that could compete with the dominant Ford GT40s and Ferrari prototypes. The result was the Porsche 917, a bold and radical design that would shake the racing world.

Why Porsche Decided to Build the 917

Porsche had been winning races with smaller, lighter cars. The 907 and 908 models were competitive, but they lacked the raw power needed to beat the big American and Italian challengers. Porsche engineers knew they needed more horsepower. The flat-eight engine they developed for the 917 produced over 1,000 horsepower in its early forms. This was unprecedented for a sports car at the time.

The decision to build the 917 was not taken lightly. It required massive investment from the car manufacturer. Porsche committed significant resources to designing, testing, and building this revolutionary machine. The project was a gamble, but it paid off in spectacular fashion. The Porsche 917 proved that bold engineering could overcome sheer power advantages from competitors.

How Many Porsche 917 Models Were Produced

The total number of Porsche 917 cars built is a subject of great interest among collectors and historians. The production numbers tell a story of a car built for racing, not for mass appeal. Only a small fleet of these machines ever left the factory in Stuttgart, Germany.

The Original Porsche 917 (Short Tail)

The first version of the Porsche 917 was the short-tailed model, often called the “917 Short Tail” or simply the original 917. Porsche built approximately 25 of these cars between 1969 and 1970. These early examples had a compact rear end that made them very fast on certain tracks. However, they were also notoriously difficult to handle. The aerodynamics were not fully optimized, which caused stability issues at high speeds.

The short-tail Porsche 917 had a 4.5-liter flat-six engine that produced around 520 horsepower. While this was impressive for 1969, the car struggled in its first racing season. At the 1969 24 Hours of Le Mans, a Porsche 917 crashed early in the race, killing a driver. This tragic event cast a shadow over the model and forced Porsche to rethink its approach to the design.

The Porsche 917K (Kurzheck)

Porsche quickly responded to the challenges of the original design. The result was the Porsche 917K, where the “K” stands for Kurzheck, meaning short tail in German. Wait, this sounds confusing. Let me clarify. The 917K actually had a redesigned, shorter rear bodywork compared to the original long-tail version. This is different from the “short tail” original model.

The 917K was a massive improvement. It was much more stable at high speeds and easier to drive. Porsche built around 120 of the 917K variants. This version became the workhorse of the Porsche racing fleet. It dominated the Can-Am series and proved competitive at Le Mans. The Porsche 917K is now one of the most sought-after classic cars in the world.

The Porsche 917LH (Long Tail)

The Porsche 917LH, where LH stands for Langheck (long tail), was designed specifically for high-speed endurance races. The long tail bodywork improved aerodynamics and top speed. This version was built for tracks like Le Mans, where straight-line speed is crucial.

Porsche produced around 16 of the long-tail variants. These cars were even more extreme than the 917K. They had longer rear sections that streamlined the car for maximum velocity. The Porsche 917LH was the version that brought Porsche its first Le Mans victories. It remains one of the most beautiful racing cars ever created.

Racing Success and the Porsche 917 Legacy

The racing success of the Porsche 917 is the stuff of legend. This car did not just compete. It dominated. The victories came thick and fast once the kinks were worked out of the design.

Le Mans Dominance

The 24 Hours of Le Mans is the most famous endurance race in the world. The Porsche 917 conquered this grueling event in 1970 and 1971. In 1970, a Porsche 917 driven by Hans Herrmann and Richard Attwood crossed the finish line first. The following year, the Porsche 917 did it again. This back-to-back dominance cemented the car’s place in racing history.

Racing at Le Mans is incredibly demanding. Cars must endure extreme heat and stress for 24 straight hours. The conditions push both machine and driver to their limits, much like the extreme heat a car can face sitting in direct sunlight, as explored in How Hot Can A Car Get In The Sun. The Porsche 917 proved it could handle these punishing conditions with remarkable reliability.

Can-Am Series Success

The Porsche 917 also found great success in the Can-Am series, a North American racing championship. In 1971, the Porsche 917K dominated the Can-Am season. The car’s massive horsepower advantage was simply too much for the competition. It was like comparing the top speeds discussed in How Fast Can A Nascar Race Car Go to everyday street cars. The Porsche 917 was in a league of its own.

The Can-Am victories showed that the Porsche 917 was not just a Le Mans specialist. It was a versatile racing machine that could excel on different types of circuits. This versatility added to its legendary status among enthusiasts and collectors.

The Famous Martini Racing Livery

No discussion of the Porsche 917 is complete without mentioning its iconic livery. The black and orange Martini Racing colors became synonymous with the car. This distinctive paint scheme made the Porsche 917 instantly recognizable on track. Today, many replica and restored Porsche 917 cars wear the Martini colors as a tribute to the original racing heritage. The livery has become one of the most recognized designs in all of motorsport.

The Manufacturing Process and Production Numbers

Understanding how many Porsche 917 cars were made requires looking at the manufacturing process. These were not mass-produced vehicles. Each one was built with painstaking care and attention to detail.

Factory Production Details

The Porsche factory in Stuttgart-Zuffenhausen was the birthplace of every Porsche 917. The production process was labor-intensive and required highly skilled craftsmen. Unlike modern cars that roll off assembly lines by the thousands, each Porsche 917 was essentially a hand-built prototype racing car that was also street-legal.

The total production number for all Porsche 917 variants combined is estimated at around 91 cars. This includes the original short-tail models, the 917K variants, and the long-tail 917LH versions. The exact number varies slightly depending on how you count prototype and development mules, but 91 is the widely accepted figure for customer-delivered cars.

Why So Few Were Built

The low production number was not a mistake. It was by design. The Porsche 917 was built to meet homologation requirements for racing. Manufacturers needed to build a minimum number of road-legal cars to qualify them for competition. Porsche built just enough to satisfy the rules. There was no business case for producing more.

The cost of building each Porsche 917 was enormous. The materials, engineering hours, and racing development all added up. This was not a car that was meant for the masses. It was a legendary race car built for one purpose: winning on the track.

Interestingly, the manufacturing approach of Porsche is similar to how some car manufacturers focus on specific markets. For instance, while Porsche built the 917 in Germany, not all car manufacturers build their vehicles in their home country, as explored in Are Any Honda Cars Made In The Usa. The 917 was a pure product of German engineering and racing passion.

How Many Porsche 917 Cars Survive Today

Of the approximately 91 Porsche 917 cars originally built, far fewer remain in running condition today. Many were crashed or destroyed during racing. Others were lost to time or neglected. Estimates suggest that around 20 to 30 Porsche 917 cars still exist in some form, and even fewer are fully restored and roadworthy.

Surviving Porsche 917 cars are incredibly valuable. They regularly sell at auction for millions of dollars. Each one is a rolling piece of automotive history. The rarity of these cars makes them some of the most desirable collector vehicles in the world.
