At this moment however it was recognized by the commission that the weight estimate earlier made by the bribed Infantry officer had been a deliberate falsehood and that the best that could be expected was 28 tonnes. Also the claimed first production date, that had already led to a limiting of Char B1 bis orders, later was proven to be wildly optimistic. In April 1938 Renault claimed that weight could be saved by retaining the torsion-bar suspension, limiting the crew to four and keeping the ammunition load to its bare minimum. The commission decided however to bring the weight limit of the project to thirty tonnes, as this was in line with the other projects and the planned inner hull side armour (located behind fifty millimetres external suspension protection plates) of ten millimetres was deemed too thin. The weight advantage in relation to the rival designs thus largely disappeared.
