Isotta Fraschini Tipo 8A SS Cabriolet

Vehicle Overview

The Isotta Fraschini Tipo 8A SS Cabriolet by Castagna stands as a testament to the pinnacle of luxury and craftsmanship in the 1920s. During this era, a tour of the world’s most exclusive motor car manufacturers would include visits to Hispano-Suiza in France, Pierce-Arrow in Ohio, Rolls-Royce in England, and Bugatti in Molsheim. Yet, the discerning aficionado would dedicate time to Milan, where Fabbrica Automobili Isotta-Fraschini, Italy’s premier car maker, resided. Founded in 1900 by Cesare Isotta and Oreste Fraschini, the company quickly progressed from showcasing their first 5hp, single-cylinder car at the 1901 Milan Exposition to achieving celebrated victories in motorsport, including the 1908 Targa Florio and a notable second place in the 1908 Vanderbilt Cup. By the 1920s, under Chief Engineer Giustino Cattaneo’s guidance, Isotta-Fraschini adopted a single-model policy similar to Rolls-Royce, introducing the world’s first production straight-eight motor car, the Tipo 8, in 1920. Early Isotta engines, with push-rod operated overhead valves and a 5.9-liter capacity, set high manufacturing standards, delivering 80hp and incorporating sophisticated mechanical, servo-operated, four-wheel brakes. In 1924, the Tipo 8A emerged with a 7.3-liter engine producing approximately 115bhp, making it the most powerful straight-eight in production. This model also featured Isotta’s highly regarded three-speed synchromesh transmission and enhanced chassis and suspension systems. The 8A was unapologetically expensive, aimed primarily at the American market, and attracted a clientele of celebrities and influential figures, including Rudolph Valentino, Clara Bow, William Randolph Hearst, and Jack Dempsey. For those desiring even greater performance and individuality, Isotta-Fraschini offered the Spinto or Super Spinto versions, featuring twin carburetors, higher compression engines producing 150bhp, and tailored rear axle ratios for increased speed. These models were often built on shorter wheelbase chassis, although coachbuilders preferred the standard chassis for their intricate designs. Among the high-quality coachbuilders associated with Isotta-Fraschini were Carrozeria Italiana Cesare Sala and Carrozeria Castagna & Co. Established in 1906 by Carlo Castagna, Castagna & Co. was renowned for its exceptional craftsmanship. Carlo managed the business and finances, while his sons Ercole and Emilio focused on design and construction. Castagna’s work, especially with Isotta-Fraschini, is epitomized by the elegant Tipo 8A SS Cabriolet, which features a well-proportioned design, extended scuttle, long bonnet, low-profile windscreen, high waist molding, and a distinctive rear with a central spine and collapsible trunk rack. This car exemplifies the blend of luxury, performance, and bespoke craftsmanship that defined Isotta-Fraschini and its illustrious coachbuilders during the golden age of automotive excellence.
