The Legendary Porsche 935: A Detailed Chronicle of Racing Excellence

 The Porsche 935 is a monumental figure in the annals of motorsport history, epitomizing the zenith of engineering, design, and racing dominance. Developed in the mid-1970s, the 935 was Porsche's answer to the FIA's Group 5 regulations, and it swiftly became a formidable force on racetracks worldwide.

Genesis of the Porsche 935

In 1976, Porsche unveiled the 935, a race car derived from the 911 Turbo (930) platform, meticulously engineered to comply with the FIA's Group 5 "Special Production Car" regulations. These regulations permitted extensive modifications, provided the vehicle retained the silhouette of the production model. Porsche's engineers seized this opportunity, transforming the 911 Turbo into a racing powerhouse.

The initial iteration of the 935 featured a 2.85-liter flat-six engine with a single turbocharger, delivering approximately 560 horsepower. This powerplant was paired with a four-speed manual transmission, channeling power to the rear wheels. The car's aerodynamics were extensively reworked, including a flattened front fascia, wide wheel arches, and a prominent rear wing, all designed to enhance downforce and stability at high speeds.

Evolution Through Innovation

Porsche's commitment to continuous improvement led to several evolutions of the 935:

935/77

In 1977, the 935/77 was introduced, featuring significant enhancements:

  • Twin-Turbocharging: The transition from a single to twin turbochargers reduced turbo lag and increased power output to around 630 horsepower.

  • Aerodynamic Refinements: The bodywork was modified to improve airflow, including the addition of a secondary rear window to direct air more efficiently to the rear wing.

  • Chassis Adjustments: The suspension system was upgraded for better handling and adaptability to various racing conditions.

935/77 "Baby"

To compete in the 2.0-liter class of the German Deutsche Rennsport Meisterschaft (DRM), Porsche developed the 935/77 "Baby":

  • Engine Downsizing: A 1.4-liter flat-six engine, equipped with a single turbocharger, produced approximately 380 horsepower, adhering to the class regulations.

  • Weight Reduction: Extensive use of lightweight materials and a simplified structure reduced the car's weight to about 735 kilograms.

Despite its smaller engine, the 935 "Baby" demonstrated remarkable performance, securing a victory at Hockenheim in 1977.

935/78 "Moby Dick"

The pinnacle of the 935 series was the 935/78, colloquially known as "Moby Dick" due to its elongated shape and white livery:

  • Engine Enhancement: The engine was enlarged to 3.2 liters, featuring water-cooled cylinder heads and dual overhead camshafts, producing up to 750 horsepower.

  • Radical Aerodynamics: The car's body was extensively redesigned, with a lowered nose, extended tail, and streamlined profile, enabling top speeds of approximately 366 km/h (227 mph) on the Mulsanne Straight at Le Mans.

  • Chassis Modifications: The chassis was reengineered to lower the center of gravity and improve handling dynamics.

Although "Moby Dick" showcased exceptional speed, it faced challenges with reliability and fuel efficiency, limiting its success in endurance races.

Racing Triumphs

The Porsche 935's racing pedigree is illustrious:

  • World Sportscar Championship: The 935 secured the championship for Porsche in 1976, ending a five-year hiatus.

  • 24 Hours of Le Mans: In 1979, a privately entered 935 K3, prepared by Kremer Racing, achieved an overall victory, a rare accomplishment for a production-based car competing against prototypes.

  • IMSA GT Championship: The 935 dominated the IMSA series in North America, with numerous wins between 1977 and 1982.

  • Deutsche Rennsport Meisterschaft (DRM): The 935 was a dominant force in the DRM, with drivers like Rolf Stommelen and Klaus Ludwig securing championships in 1977 and 1979, respectively.

Overall, the 935 participated in 370 races, clinching 123 victories, underscoring its dominance in the racing arena.

Legacy and Modern Homage

The influence of the Porsche 935 extends beyond its original production years:

  • Customer Teams and Variants: Porsche's policy of providing 935s to customer teams led to various successful variants, notably the Kremer K3 and K4, which featured further enhancements and achieved significant racing success.

  • 2018 Porsche 935 Tribute: To commemorate the 70th anniversary of Porsche's motorsport heritage, a modern interpretation of the 935 was unveiled in 2018 at the Rennsport Reunion VI at Laguna Seca Raceway. This limited-edition, track-only car is based on the 911 GT2 RS, featuring a 3.8-liter twin-turbo flat-six engine producing 700 horsepower. Its design pays homage to the original "Moby Dick," with a streamlined body and iconic livery. Production was limited to 77 units, making it a coveted collector's item.

The Porsche 935 remains a symbol of innovation, engineering excellence, and racing success, embodying Porsche's relentless pursuit of automotive perfection.
