Description

Pierre DUMONT (1920–1987) Bugatti Royale Roadster Type 41 12.8-litre 1932 Gouache on card 18 x 50 cm (signs of damp, mould and soiling) Notes: “Although some pre-First World War cars had engines even larger than that of the Bugatti Royale, and even a longer wheelbase, the Type 41 was the giant of its era. Seven Royales were built; five still exist in the USA and one in France. Commercially, it was a failure and, in fact, none was ever sold to a monarch. The engine was typical of the make, with its eight-cylinder in-line layout and a single overhead camshaft operating three valves per cylinder; externally, it was a masterpiece of architectural symmetry. Its displacement was 12,763 cm³ (125 x 180 mm) and its power output 300 CV at 1,700 rpm. The engine had to be completely removed and dismantled in order to run it in or replace a valve. The three-speed gearbox, with a direct drive in second gear, was mounted directly onto the axle. The theoretical top speed in third gear was 170 km/h. The chassis was strictly conventional, without even a servo to assist the mechanically operated brakes. The Royale’s engine was mass-produced to power French railway railcars. [Here], the roadster is said to have been designed by Jean Bugatti for Mr Esders.’ Bibliography: P. DUMONT, *Aux Temps Des Automobilistes*, Lazarus, 1965, our gouache reproduced on p. 137.
