History of the French automotive
industry

Having
started with designing of steam-engines, "De Dion-Bouton" in 1885 has designed modest by sight
the engine power of 0,5 h.p., than has brought the essential
contribution to car creation: it was the first high-speed automobile
engine working in a mode of 1500 ob./minutes, but capable to work
and for 3000 ob./minutes, thus not collapsing on a part.
For
comparison: engine "Daimler" could brag only 700-900 ob./minutes
This facilitated power unit at once has put the gasoline engine
ahead of gas and steam primogenitors, having bypassed them under the
technical and high-speed characteristics: reasonableness of a
mechanical part and, the main thing, the ignition breaker (for
prevention of any growth of number of revolutions). Such engine has
been installed on Dion's three-wheeled car De of 1895, and its power
constantly increased: from 0,75 h.p. to more impressive of 2,75 h.p.
New vehicles, inexpensive, easy in service
and simple in circulation, used steady demand. Soon some firms began
to alter them in four-wheel cars, constructing a place for the
passenger over a new front axle. "De Dion-Bouton" at once has
responded to inquiries of the market and in 1899 has exhausted the
four-wheel car ("voiturette").
The new improved version by power of 3,5 h.p.
represented known model "De Dion", with an original design of the
rear bridge and successfully grouped, that has allowed to reduce its
weight. It was not opening - such decision was already used on steam
cars, - yes for it and did not apply Dion, the Bud; but rather
successful scheme of the rear bridge - in it engineers of variety of
known firms, such as "Lancia" and "Rover" has been groped, many
years were convinced later.
Carefully developed by De Dion and the Bud
small one-cylinder cars have won popularity and have held on in the
market till 1912, despite occurrence of two-cylinder and
four-cylinder models. Reliability, comfort, simplicity in control
and sufficient power were the reason for that. Besides it the engine
"De Dion-Bouton" with 1898 for 1908 has given a life to one hundred
different versions, and they, in turn, - to many rather prestigious
cars.
