De Dion-Bouton - Expansion

Expansion

In 1900, De Dion-Bouton was the largest automobile manufacturer in the world, producing 400 cars and 3,200 engines. The company soon began producing engines and licenses for other automobile companies with an estimate of 150 makes using them. Production was so great, it proved impossible to test every engine; if it failed on the bench, it was simply disassembled. Every engine was being made by hand; the assembly line had not yet been introduced. By 1904 some 40,000 engines had been supplied across Europe. That year, De Dion-Bouton's factory at Quai National (now Quai de Dion-Bouton), Puteaux, employed 1,300 and produced more than 2,000 cars, all also by hand.

The engine moved to the front in 1903 in the Populaire with 700 or 942 cc (43 or 57.5 cu in) engines, the latter being powerful enough to allow trucks to be added to cars, and by the end of the year reverse gear had also appeared. It was joined by the 6 CV (4 kW) 864 cc (52.5 in3) Types N and Q (the latter a low-priced K), the 8 CV (6 kW) R, and their first multi-cylinder model, the two-cylinder 1728 cc (105 in3) 12 CV (8 kW) S, followed in 1904 by the four-cylinder 2,545 cc (155.3 cu in) 15 CV (11 kW) Type AD and 24 CV (18 kW) AI. The cars were also getting more and more conventional in styling, with the radiator moving in front of the engine and the clutch changing from hand lever to pedal.

A pair of works 10 CV (7.5 kW) De Dion-Boutons, in the hands of Cormier and Collignon, ran in the 1907 Peking to Paris rally, without success. Bouvier St. Chaffray did no better in the New York to Paris in 1908. That year, De Dion-Bouton peaked as a manufacturer.

The company became the first to make a successful mass-produced V8 engine, a 35 CV (26 kW) 6,107 cc (372.7 cu in) CJ in 1910, followed by a 7.8 liter and a 14.7 liter for the U.S., as well as by a 3,534 cc (215.7 cu in) Type CN in 1912. (They trailed Ader in racing the 1906 Adams, which used an Antoinette aircraft engine.) This would be the company's last innovation.

During World War I the company made gun parts, armoured vehicles, and aircraft engines, as well as cars and trucks. The company produced an anti-aircraft version of the French 75 mm field gun mounted on a V8-powered De Dion-Bouton truck for the French Army between 1913 and 1918.

Famous quotes containing the word expansion:

    The fundamental steps of expansion that will open a person, over time, to the full flowering of his or her individuality are the same for both genders. But men and women are rarely in the same place struggling with the same questions at the same age.
    Gail Sheehy (20th century)

    Every expansion of government in business means that government in order to protect itself from the political consequences of its errors and wrongs is driven irresistibly without peace to greater and greater control of the nation’s press and platform. Free speech does not live many hours after free industry and free commerce die.
    Herbert Hoover (1874–1964)

    We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventions—telephones, electricity, steel bridges, horseless vehicles—they are all leading somewhere. It’s up to us to be on the inside in the forefront of progress.
    John Dos Passos (1896–1970)
