Comparing: Renault G1 vs. BDR G1 B vs. ARL 44

Developed from 1935 through 1940. The vehicle was comparable to the T-34 in terms of its characteristics. Among several presented prototypes, the Renault G1R project was eventually selected. The vehicle had individual torsion-bar suspension and an innovative gun-mounting scheme. A prototype was built by 1940. However, the development was stopped when France was defeated later that year.

The project of a new vehicle was suggested by engineers of the Baudet-Donon-Rousell company in June 1938. However, the design was never developed.

Development of the vehicle started while France was still occupied by the German forces. It was an attempt to use the obsolete B1 Bis chassis and fit it with a modern, more powerful gun. The project was finished by the Atelier de Construction de Rueil Design Bureau. A total of 60 vehicles were manufactured. However, the tank was considered unsuccessful compared to similar foreign vehicles.
