Type O6 45/50 Double Pare-Brise by Rothschild





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. It was an advanced four-cylinder design, machined to a high standard.

The massive O6 chassis was launched in late 1913, a few months before the beginning of World War I. It was a natural progression from the previous exclusive models, and the dual-ignition 8-liter engine was a technical tour de force: six cylinders cast in two blocks of three, side valves, full pressure lubrication, and an oil pump driven directly from the camshaft. In keeping with Delaunay-Belleville's marine heritage, the oil pump was designed like a small steam engine where an oscillating piston pumped and distributed the oil. A pressure gauge is fitted to the dashboard, and pump action can be controlled by the driver. 100 horsepower was developed at a very conservative 1,500 rpm, and power was fed through a multiplate dry clutch, another recent Delaunay-Belleville innovation. Production was curtailed by the War, and it is believed that a mere 55 O6 chassis were built.

The company started with three models, all fours: a live axled 16hp (12 kW; 16 PS) and a 24hp (18 kW; 24 PS) and 40hp (30 kW; 41 PS) 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 2 imp gal (9.1 l; 2.4 US gal) 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 70hp (52 kW; 71 PS) 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 coach built 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 26hp (19 kW; 26 PS) 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 10hp (7.5 kW; 10 PS) four-cylinder, undoubtedly the most expensive voiturette on the market, as well as a 15.9hp (11.9 kW; 16.1 PS) 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 20hp (15 kW; 20 PS) and 10hp (7.5 kW; 10 PS) six-cylinder models continued to be produced until 1927. The last gasps were the 3,180 cc (194 cu in) 21hp (16 kW; 21 PS) six of 1928 and the 3,619 cc (220.8 cu in) 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.
