The project of "Lorraine de Dietrich" was based on its 1933 design for a light infantry tank. It was low and long with an excellent trench crossing capacity. This however implied there was no room for a 75 mm hull-based gun; its calibre was reduced to 47 mm, which seemed redundant given that it also had a 47 mm gun in an APX4 turret. The track was that of Carden-Loyd and considered too weak by the commission, as with the G1F project. Similarly the initial proposal to fit a Cleveland transmission was seen by the commission as unsuitable, and it was replaced by a Cotal. The planned engine was a Hispano-Suiza of 230 hp. The length was to be 550 cm, and the width was to be 250 cm.
