The Grégoire-IHA Collection

The collection essentially consists of 11 unique cars or prototypes, among which we can distinguish:

• a Tracta, the first "front-wheel drive" car designed by J.-A. Grégoire with the help of his friend Pierre Fenaille. It is similar to the car with which J.-A. Grégoire raced in the 24 hour Le Mans race from 1927 to 1930, which excelled in its category.

• the  Adler Junior prototype , the first example of the use of a cast aluminium structural part.

• the Amilcar Compound (1937), the first car with a cast aluminium body.

• the AFG prototype (Aluminium Français Grégoire, 1942) and a forebearer for the Dyna Panhard (1951).

• the Grégoire R prototype and a Hotchkiss-Grégoire coach.

• two electric cars: the  CGE Tudor and the CGE Grégoire.

• a Renault-Dauphine equipped with the so-called "aerostable" Grégoire suspension system.

• one of the rare Grégoire Sport convertibles whose bodywork was designed by Chapron.

The collection also includes various chassis in cast aluminium alloys, which showcase the technique developed by J.-A. Grégoire and even some aluminium mechanical parts: differential housings, front axles, engine casings, drum wheels... but also wind tunnel models,  paintings, cups, medals, books and manuscripts, because in addition to his work as an engineer, J.-A. Grégoire was also a writer.
