Of course, Louis Renault did his best to overturn this decision. On 1 April 1940 a subcommission received Renault's head engineer Serre, who argued it would be folly to discontinue the Char G1 project as it was so near fruition. The first armour set would be manufactured by "Schneider" in July 1940, the suspension and gearbox were almost finished, and a new 350 hp engine was being tested. (He didn't mention this had met much resistance from Louis Renault, who thought the existing engine used in the Char B1 was sufficient, if uprated.) The weight would be lower than 35 tonnes, perhaps as low as 32 tonnes. All theoretical studies could be completed in May and the first vehicle in September. This Commission, not as easily swayed as the previous one as the manipulation by Renault had become known, answered that the prototype could of course be finished as ordered, but that production of the type, despite its interesting advanced technological features, was excluded. The armistice of June 1940 ended all development.
