Dubonnet-Xenia wins "Most Elegant Closed Car" at 2000 Pebble Beach Concours

Updated: Jan 9, 2019

Procured and restored by Charles Bronson and his team at Boulevard Motorcar Company, Hispano-Suiza H6C Dubonnet-Xenia has won "Most Elegant Closed Car", at the 2000 Pebble Beach Concours D'Elegance.

Winner of the Most Elegant Closed Car award at the 2000 Pebble Beach Concours, this is a streamlined design of a car company known also for its aircraft manufacturing, and due to it's conceptualization from a WWI fighter pilot, Andre Dubonnet, heir to the Dubonnet aperitif business and race car driver. All windows are curved glass, the panoramic windshield, gullwing windows, and suicide doors.

Engine design was shared between the aircraft and cars... one crankshaft was carved from a 700 lb billet steel block. Consider that the types of engines in the 30's were huge displacement and fewer cylinders, like a 487 cu in straight 6 cyl. The Hispano Suiza had aluminum cylinder block and overhead camshafts at a time when Rolls-Royce's venerable Silver Ghost was still using side valves, and an iron block cast in several pieces.

It was also ahead of Rolls-Royce in the braking department. While the Rolls had brakes on the rear wheels only, the Hispano had four-wheel brakes, servo assisted by a shaft driven off the rear of the transmission. Rolls-Royce later adopted this system under licence from Hispano and used it for many years.
