Porsche 904
The Ultimate Guide
After having withdrawn from Formula One at the end of the 1962 season, Porsche focused again on sports-car racing. The 904 debuted late in 1963, for the 1964 racing season, as a successor to the 718, which had been introduced in 1957. Porsche designed the GTS variant to compete in the FIA-GT class at various international racing events. The street-legal version debuted in 1964 in order to comply with group 3 appendix J homologation regulations requiring a certain number of road-going variants be sold by the factory. Several versions were made.

The Porsche 904: The Stunning Racer That Combined Style, Innovation, and Success
The Porsche 904, also known as the Carrera GTS, is one of the most celebrated race cars in Porsche’s history. Introduced in 1963 for the 1964 racing season, the 904 was a game-changing model that blended stunning design, innovative engineering, and formidable performance. It marked a shift in Porsche’s motorsport approach, showcasing the company's commitment to both competition success and road-going practicality. The 904’s legacy lives on as a symbol of mid-20th-century automotive innovation and as one of the most beautiful race cars ever produced.
Origins and Development
The Porsche 904 was born out of a need to compete in the FIA-GT class under the newly revised Group 3 regulations. To qualify for homologation, Porsche had to produce a minimum of 100 units for sale to the public. The 904 was the first Porsche to use a fiberglass-reinforced plastic (FRP) body bonded to a steel ladder frame, a groundbreaking approach that reduced weight while maintaining structural rigidity. Designed by Ferdinand "Butzi" Porsche, the 904 featured a sleek, aerodynamic profile with clean lines and a low-slung silhouette.
Under the rear deck, the 904 was initially powered by a 2.0-liter, four-cylinder, air-cooled "Fuhrmann" engine, producing around 180 horsepower. This engine was paired with a 5-speed manual transmission. The mid-engine layout provided excellent balance and handling, making the 904 a nimble and capable racer. Later variants of the 904 were equipped with six-cylinder and even eight-cylinder engines, offering more power and versatility.
Racing Success
The Porsche 904 quickly established itself as a formidable competitor on the international racing scene. In its debut season in 1964, the 904 claimed an impressive victory at the Targa Florio, driven by Antonio Pucci and Colin Davis. This win underscored the car’s durability, handling, and adaptability to challenging road conditions.
The 904 continued its success with a class victory at the 24 Hours of Le Mans in 1964, finishing seventh overall. This performance highlighted the car's reliability in endurance racing, a key attribute that would define Porsche's motorsport philosophy for years to come. The 904 also secured victories at the 12 Hours of Sebring and numerous hill climb events, proving its versatility across different racing disciplines.
One of the 904's most notable strengths was its ability to compete against more powerful rivals. Despite being outgunned by larger-displacement competitors, the 904's lightweight design, excellent aerodynamics, and superior handling allowed it to punch above its weight class. The 904's success in GT racing and prototype classes helped solidify Porsche's reputation for building race cars that prioritized efficiency, reliability, and agility over sheer horsepower.
Design and Innovation
The Porsche 904's design was both functional and beautiful. Its aerodynamic shape minimized drag and maximized high-speed stability, while the mid-engine layout provided balanced weight distribution. The use of fiberglass bodywork was a pioneering step for Porsche, showcasing their willingness to experiment with new materials and manufacturing techniques.
The 904 featured a low-profile nose, pop-up headlights, and a sharply raked windshield that enhanced its aerodynamic efficiency. The interior was minimalistic yet functional, designed to keep weight low while providing essential instrumentation for racing. The car's lightweight construction, combined with its reliable engine and sophisticated suspension, made it one of the most competitive and enjoyable race cars of its era.
Variants and Evolution
While the original 904 Carrera GTS featured a four-cylinder engine, Porsche also experimented with different powerplants to enhance performance. The 904/6 variant was equipped with the 2.0-liter six-cylinder engine from the Porsche 911, providing more power and torque. Additionally, the 904/8 featured an eight-cylinder engine, further expanding the car's capabilities.
These variants allowed Porsche to compete in different classes and adapt the 904 to the demands of various racing events. The versatility of the 904’s chassis and design laid the groundwork for future Porsche race cars, including the 906 and 910, which would build on the innovations introduced by the 904.
Legacy of the Porsche 904
The Porsche 904's impact on motorsport and automotive design cannot be overstated. It demonstrated that lightweight construction, aerodynamic efficiency, and balanced handling could triumph over raw power. The 904's victories in endurance racing, hill climbs, and road events solidified Porsche’s reputation as a leader in motorsport innovation.
Today, the Porsche 904 is highly sought after by collectors and enthusiasts, with surviving examples commanding significant prices at auctions. Its timeless design, racing pedigree, and pioneering engineering make it a cornerstone of Porsche’s racing history. The 904 also influenced the design language of future Porsche models, blending form and function in a way that continues to inspire the brand's road and race cars.
The Porsche 904 remains a testament to Porsche’s relentless pursuit of excellence, innovation, and performance—a philosophy that continues to define the brand to this day.
