Automobiles Grégoire

Automobiles Grégoire was a French manufacturer of cars and aero engines, established in 1902 in operation for about 20 years.

The company grew from an earlier enterprise making engines under the name "Cyclone", established in 1899 by Louis Soncin, in Poissy, but was largely the creation of Pierre Joseph Grégoire (1876 - 1962).

After World War I, Grégoire introduced its first car with an overhead-valve engine.

From these, the company evolved towards aircraft engines- "Moteurs d'Aviation Grégoire-Gyp"- made at Suresnes.
