Automobiles Delaunay-Belleville was a French luxury automobile manufacturer at Saint-Denis, France, north of Paris. At the beginning of the 20th century they were among the most prestigious cars produced in the world, and perhaps the most desirable French marque.
Julien Belleville had been a maker of marine boilers from around 1850. Louis Delaunay joined the firm in 1867 and married Delaunay's daughter, changing his name to Delaunay-Belleville and succeeded Belleville in charge of the company.
S.A. des Automobiles Delaunay-Belleville was formed in 1903 by Louis Delaunay and Marius Barbarou. Barbarou's family owned the boiler making company St. Denis in Belleville, with boiler design influences inspired by the company. Barbarou, then 28, had experience working for Clément, Lorraine-Dietrich and Benz and was responsible for design and styling, including the trademark round grille shell. The first car was exhibited at the 1904 Paris Salon, and it received enormous acclaim.
The company started with three models, all fours: a live axled and a and model, both chain-driven. These were likely the first automobiles to have pressure-lubricated camshafts. The bodies were attached with just four bolts, and the brakes were water-cooled, from a reservoir.
Delaunay-Belleville were a prestige marque, and one of the world's leaders, from the outset, and by 1906, Tsar Nicholas II. had purchased a 40. Other royal owners included King George I of Greece and King Alphonso XIII of Spain.
The first French car maker to offer a six-cylinder engine, Delaunay-Belleville's became available only in 1909, and then only in small numbers, remaining in limited production until 1912. This model came to be known as the Type SMT, or Sa Majesté le Tsar, because Nicholas purchased one of the last 70s built. He also ordered another in 1909; the demand for a silent starter, operable from the driving seat, became known as a Barbey starter, and was made standard at the end of 1910.
Like most prestige marques, the cars were sold as bare chassis and bodies were coachbuilt for them. Between 1906 and 1914, British imports were mainly bodied by Shinnie Brothers, a Burlington subsidiary, in Aberdeen, then shipped to London for sale.
Postwar, Continental bodies gained popularity, at least in Britain, as Belgium's D'Ieteren Fréres became most associated with the company: their landaulette, on a chassis, was priced in Britain at ₤900, between Napier and Rolls-Royce.
After Barbarou resigned, Delaunay-Belleville quality began to slip. In 1919, the company offered a four-cylinder, undoubtedly the most expensive voiturette on the market, as well as a four, the P4B, in 1922.
French anarchist gangster Jules Bonnot used a Delaunay-Belleville for his first hold-up.
New four-cylinder overhead valve 14/40 and 16/60 models appeared in 1926, and the prewar and six-cylinder models continued to be produced until 1927. The last gasps were the six of 1928 and the 21/75 OHV six of 1930. In 1931, Continental engines, imported from the U.S., were offered, being quieter and cheaper.
By the late 1920s, Delaunay-Belleville had lost its prestige, and converted to truck and military vehicle production. In 1936 the previously separate car company was merged with the Delaunay Belleville parent. Production of the Delaunay-Belleville RI-6 continued through the late 1930s and was revived after the Second World War. This was a six-cylinder-engined car strongly resembling the Mercedes-Benz 230, featuring independent suspension all-round; revived postwar, it featured Cotal preselector gearbox and a front grille design apparently copied from the 1939 Buick. However, the business was in decline: anyone buying a RI-6 in the 1940s would have done so in the knowledge after-sales service might disappear soon. Six cars were completed in 1947 and this sank to four during the first part of 1948.
The company continued to advertise new cars for sale until 1950, but the factory was sold to Robert de Rovin in 1948 and thereafter used to make cyclecars.
