01 / THE STORY

History & context

The Alfa Romeo 6C 2300 Coupé Aerodinamico is a rare and historically significant automobile that reflects the elegance and engineering prowess of pre-war Italy. Originally manufactured in 1934, this exceptional car was produced as a fixed-head coupé by Carrozzeria Castagna Milano, a renowned coachbuilder known for crafting bespoke and luxurious automobile bodies. The car’s striking appearance features a two-tone grey body with black fenders, exemplifying the aerodynamic styling that was avant-garde at the time. The interior is equally distinguished, featuring red leather seats that add a vibrant contrast to the exterior. Under the hood, the Alfa Romeo 6C 2300 Coupé Aerodinamico is powered by a robust six-cylinder engine, although no engine number is recorded. The car’s chassis number is 700.500, indicating its unique identity among Alfa Romeo’s 6C series. The 6C 2300 itself was a significant model for Alfa Romeo, representing a shift towards more refined and powerful touring cars, while maintaining the marque’s commitment to innovation and performance. Throughout its life, the 6C 2300 Coupé Aerodinamico has been preserved with great care. In 1994, it was documented in John Fulton De Boer’s “The Italian Car Registry,” marking its continued recognition among classic car enthusiasts. In 2010, the car was featured in the “Uniques 2010” publication and was displayed at the Uniques Special Ones International Concours held in Florence, Italy, from September 24th to 27th, where it bore the race number #96. This event celebrated some of the most unique and historically significant cars from around the world. In 2014, Fabio Morlacchi included the car in his volume dedicated to the Alfa Romeo 6C 2300 and 6C 2500 series, further affirming its importance within the Alfa Romeo legacy. Today, the car is proudly housed at the Museo Alfa Romeo in Italy, where it remains a celebrated piece of automotive history, admired for its design, craftsmanship, and the legacy it represents within the Alfa Romeo lineage.
