The 1966 Porsche 906 remains one of the most significant pillars in the history of endurance racing. Officially known as the Carrera 6, this model marked a departure from the earlier ladder chassis designs toward a more advanced multi-tubular frame. Only 65 of these aerodynamic masterpieces were ever constructed at Zuffenhausen to compete on the world stage. This particular example, chassis 906-115, was originally delivered to Italian hillclimb specialist Ermanno Spazzapan in the spring of 1966. It represents a rare opportunity to own a vehicle that successfully bridged the gap between amateur racing and factory-level performance. Because of its lightweight construction and reliable flat-six power, it became a frequent sight on podiums across Europe. The 1966 Porsche 906 is a true giant-killer that continues to inspire awe in collectors and vintage racers alike.
Italian Racing Pedigree and Championship Success
Competing under the pseudonym “Mann,” Spazzapan immediately pushed this 1966 Porsche 906 to its limits in domestic events. The car secured an outright victory at the Antignano–Monte Burrone hillclimb and a second-place finish at Vallelunga. In 1967, the vehicle transitioned to Ennio Bonomelli and began a rigorous campaign in international circuit racing. Its most notable performance occurred during the Imola 500 Kilometers, where it finished a remarkable fourth overall and first in class. Facing off against heavyweights from Ferrari and Alfa Romeo, the 906 proved its mechanical superiority and enduring speed. This chassis also tackled the grueling road circuit of the Circuito del Mugello, finishing tenth overall against works prototypes. Such a documented and successful competition record provides an incredible level of provenance for any serious motorsport historian.
Preservation and Meticulous Marque Maintenance
Following its contemporary racing career, this 1966 Porsche 906 was acquired by the prominent German collector Bernd Becker. He retained the vehicle for nearly twenty-five years, ensuring its survival in a highly original and functional state. During a later comprehensive rebuild, the car was noted for retaining its original GRP body panels and numbers-matching gearbox. Recently, the car received over sixty thousand dollars in specialized care from the experts at Road Scholars in North Carolina. This work involved rebuilding the carburetors and steering rack, along with calibrating the engine for optimal track performance. It even participated in a 300-mile road trip through the Colorado Rockies to celebrate its Alpine heritage. These investments guarantee that the car remains mechanically sharp and ready for the rigors of modern historic competition.
Engine Specifications and Racing Engineering
Power for the 1966 Porsche 906 comes from a 2.0-liter Type 901/20 six-cylinder engine that delivers roughly 210 horsepower. This engine utilizes a sand-cast magnesium crankcase, titanium connecting rods, and forged steel crankshafts to reach an 8,000 rpm redline. A compression ratio of 10.3:1 ensures the motor produces the high-revving soundtrack that enthusiasts expect from a period Porsche. Gear changes are handled by a five-speed Type 906/1 manual gearbox that remains original to this specific chassis. To minimize total weight, the unstressed fiberglass bodywork is draped over a sophisticated tubular space frame design. Braking performance is managed by a dedicated system that was revolutionary for a 2-liter sports racer in the mid-sixties. This lightweight and aerodynamic package allows the 906 to maintain incredible cornering speeds on technical circuits. It is a pure racing machine that emphasizes balance and mechanical efficiency over raw, unbridled horsepower.
Summary of a Sports Prototype Icon
The 1966 Porsche 906 is a masterpiece of functional design that defines the golden era of sports car racing. Chassis 906-115 stands out as a premier example due to its continuous ownership chain and verified racing results. It comes accompanied by an original Kardex and an extensive report from world-renowned Porsche expert Jürgen Barth. Whether competing in the Le Mans Classic or the Goodwood Revival, this car offers unparalleled eligibility and performance. The recent mechanical sorting by Road Scholars means it is one of the few prototypes ready for immediate track use. Its combination of an original GRP body and a numbers-matching gearbox is a rarity in the world of historic prototypes. This Porsche 906 is not just a collector’s item but a functional participant in the history of speed. It remains one of the most versatile and rewarding vehicles ever to leave the factory at Zuffenhausen.
