Compagnie des Moteurs Gobron et Brillié. French maker of early cars.
1898 The Societé des Moteurs Gobron-Brillié was founded by engineer Eugène Brillié and industrialist Gustave Gobron, at Boulougne-sur-Seine, near Paris. Brillié had developed an unusual type of engine having with two opposed pistons in each cylinder.
Brillié left the company in 1903 to join the Ateliers Schneider at Le Havre (formerly the Ateliers d’artillerie des Forges et Chantiers de la Méditerranée, which had been bought by Schneider in 1897). There, he built touring cars and commercial vehicles of more conventional design.
After the First World War, the company changed name to Automobiles Gobron, and moved to new premises at Levallois-Perret. The design continued to use opposed-piston engines until 1922.
In 1922 a more conventional 1·5-litre Chapuis-Dornier engine was adopted, and the cars were additionally marketed under the name of Stabilia. Sales were poor, and the company became bankrupt in 1930.
