Throughout their history, the Gregoire cars from Possy were best known as fast, if conventional, small cars, though larger Gregoire cars were also made. Their earliest range, for 1904, consisted of a Gregoire 8CV single, a Gegoire 12CV twin, and a Gregoire 20CV four, but the first famous Grégoire appeared two seasons later, an 80x110mm twin. In 1908 a Gregoire could be had in 4-cylinder form as well as a 2-litre 10CV. Both Gregoire cars for sale were modern L-head Monobloc fours. In 1911 came the most celebrated Gregoire of all, the Gregoire 16/24hp with the same bore but the remarkably long stroke of 160mm. This Gregoire was a car of sporting performance that had originated as a racing voiturette, as the ultra-long stroke suggests. Both the Gregoire 10cv and the Gregoire 16/24 were listed in 1914, together with a new T-head sports model of 70x140mm, also with four cylinders. Its engine developed 38bhp at 2.500rpm, aided by light steel pistons and a short, stiff crankshaft. The Gregoire 10cv was still in evidence after World War 1. Even at that stage in its career, its efficient, high-speed engine, enlarged to 2.3-litres in 1921 and given overhead valves, made the Gregoire car an exceptionally fast car, capable of over 60mph. The last car to bear the Gregoire name was an 1.100cc overhead-valve voiturette of normal type, with three forward speeds and transverse-spring front suspension. This Gregoire car was in fact made by Hinstin and sold under the name Little Greg in Britain. The Gregoire factory was also responsible for the assembly of the 3-litre Bignan.
