Gobron-Brillié was the name of first car which had achieved the speed of 100 mph around 1904. It was an early French automobile manufactured from 1898 to 1930. Louis Rigolly was the first person who had this achieved this speed using this car. On 17 July, Rigolly became the first person to exceed 100 mph with an averaging of 103.56 mph per kilometre on his 15-litre four-cylinder Gobron-Brillie in Ostende Automobile Week.

The French company Societé des Moteurs Gobron-Brillié was established in 1898 by industrialist Gustav Gobron and engineer Eugene Brillié. Eugene Brillié brought with him a rather unusual engine design that featured two opposed pistons in one cylinder. The ignition stroke was subsequently triggered between them when the compression stroke involved the two pistons approaching each other. A revolving petrol distributor was developed, instead of a carburettor, with the quantity of fuel being regulated by a drip-feed. The engine was mounted at the rear on a triangulated tubular chassis.

It was mounted with chain-drive to the wheels. This design produced a 15-litre four cylinder powered Gobron-Brillié. Brillié had left the company in 1903. Eugene Brillié is a French engineer who studied at the École centrale des arts et manufactures and began his career from 1887 to 1898 in the Railway Co. of the West. He studied at the Central School of Arts and Manufactures. Gustave Gobron started as director of Godillot, a supply company to the military, before he created a car manufacturing company, under his own name.

Eugene Brillié joined with Gustave Gobron to create the Society of Motor GOBRON-Brillié and develop very specific type of internal combustion engine he had invented, in which each cylinder has two opposing pistons. Gobron-Brillié opposed-piston engine, with overhung yoke. After the world War, Gobron-Brillié did not resume production until 1922 and without the engineering genius of Eugene Brillié, the company failed to maintain its name. The manufacturer was forced to file for bankruptcy in 1930. Nowadays only some examples of cars are alive. Louis Rigolly in his car which first exceeded 100 mph in 1904. Gobron-Brillié was excluded from the 1908 French Grand Prix in what was effectively the start of formula racing to control the sport in general, and engine size in particular.
