Ferrari 375 MM Spider Scaglietti

Vehicle Overview

The Ferrari 375 MM Spider by Scaglietti chassis 0366AM represents a singular variant within Ferrari’s mid-century sports racing lineage. Originally completed in 1953, the chassis bearing the number 0366AM was first bodied by Pinin Farina. Following damage sustained during its competitive use, the vehicle was rebodied in 1954 by Carrozzeria Scaglietti. This rebodied form, distinguished by its aerodynamic simplicity and functional design, reflects the evolution of sports racing aesthetics and engineering in the early 1950s. The 375 MM series derives its name from the engine’s unitary displacement—375 cubic centimeters per cylinder—yielding a total capacity of 4.5 liters. The V12 engine, based on the Lampredi long-block design originally developed for Formula One competition, was front-mounted and longitudinally positioned. It featured a bore and stroke of 84 x 68 mm, with dual overhead camshafts and a dry sump lubrication system. Output was rated at approximately 340 horsepower at 7,000 revolutions per minute. Power was transmitted through a four-speed manual gearbox to the rear wheels. The chassis consisted of a tubular steel frame, employing independent front suspension with unequal-length wishbones and a transverse leaf spring, while the rear utilized a live axle supported by semi-elliptic leaf springs. Scaglietti’s aluminum coachwork displayed a restrained yet purposeful design language. The car’s long, low profile, integrated fenders, and minimal cockpit structure emphasized aerodynamic efficiency and ease of serviceability in competition. The rebodied spider configuration contributed to a total dry weight of approximately 900 kilograms, permitting a maximum speed exceeding 280 kilometers per hour. Although this specific example’s individual competition record is not comprehensively documented, the 375 MM model series secured multiple victories in international endurance events, including the 12 Hours of Pescara and the 24 Hours of Spa. The model’s performance capability and technical configuration established it as a competitive platform during a transitional period in sports car racing. As a limited-production vehicle featuring bespoke coachwork, the 375 MM Spider by Scaglietti occupies a significant position in Ferrari’s development history. It represents both the culmination of early V12 racing experimentation and a precursor to the standardized yet sophisticated GT and sports prototypes that would dominate endurance racing in the following decade.
