The 1923 Hispano-Suiza H6B Cabriolet, chassis number 10734, is a concours-winning example of one of Europe’s most technically advanced and aesthetically elegant automobiles of the interwar years. Winner of First in Class at the 2024 Pebble Beach Concours d’Elegance, this Hispano-Suiza combines Fernandez et Darrin’s sleek cabriolet coachwork with the marque’s aircraft-derived engineering to create a motorcar of exceptional presence. Finished in black over light gray leather with nickel-plated trim, the H6B represents a world-class candidate for the most exclusive concours events worldwide.

Chassis 10734 was purchased new in June 1923 by Albert Venot. While the original body is not recorded, factory documentation suggests that the Hispano-Suiza was returned in 1929 for rebuilding, with Fernandez et Darrin completing the present Cabriolet bodywork in 1932. In the 1950s, the Hispano-Suiza was discovered in a French salvage yard, with the chassis and engine numbers verified against the original Venot car. The H6B was later acquired by collector Mr. Bitel and then passed to Dutch enthusiasts Jan Bruijn and J.A. Palman in the late 1980s. After a period of incomplete restoration, the Hispano-Suiza was sold to Otis Chandler in 2002 and entered the care of Stu Laidlaw in California. Following Chandler’s passing, George Fernandez of Spain assumed ownership before being acquired by collector Sam Mann in 2015, who completed the restoration. Today, the Hispano-Suiza is offered in fully restored, concours-winning condition with a fascinating and well-documented history.

The exterior coachwork by Fernandez et Darrin is finished in a sleek black with nickel-plated hardware throughout, in overall excellent condition. The Hispano-Suiza features a folding black soft top, dual coach doors with nickel handles, Marchal headlights, sweeping fenders with art deco accent lamps, and the marque’s signature Flying Stork mascots at both the radiator and rear deck. Dual windshields, including a cleverly concealed screen for rumble seat passengers, provide elegance and functionality. Full cloth side mount wheel covers, and a prominent grille complete the striking, period-correct presentation.

The interior is upholstered in light gray leather with black piping, complemented by matching grey carpets and floor mats which are all in excellent condition. Mahogany wood trim adorns the doors and dashboard, while the etched nickel-plated instrument panel features Jaeger gauges labeled in French, including a 130 km/h speedometer and matching auxiliary instruments. The right-hand drive configuration, complete with steering wheel throttle controls and a floor-mounted shifter, reflects the car’s original sporting character. A Cognac Brown convertible headliner and nickel-plated hardware complete the thoughtful, authentic finish. Every element of the Hispano-Suiza’s interior reinforces the quality and craftsmanship expected of one of Europe’s premier luxury marques.

The Hispano-Suiza H6B was engineered by Swiss designer Marc Birkigt and became legendary for its technical sophistication. Powered by a 6.6-liter inline six-cylinder derived from aviation practice, the H6B employed steel cylinder liners in an aluminum block, overhead camshaft valve actuation, and a pressure-lubricated crankshaft with seven main bearings. Servo-assisted four-wheel brakes, patented by the marque, gave the Hispano-Suiza stopping power unmatched by contemporaries. Chassis 10734 retains its early-style rear axle assembly and crankcase, with evidence of an updated block dating from the 1929 rebuilding, while original components including the carburetor, distributor caps, and valve covers remain present. The Hispano-Suiza runs very well, reflecting both the brilliance of its engineering and the care invested in its recent restoration.
