It had been considered to use a more modern pneumatic suspension, but when the armour was increased a choice was made for a traditional configuration with steel coil springs and hydraulic shock-breakers, as the rubber seals of the pneumatic elements could not withstand the higher pressures. The type has often been compared to the many "Super Char B" projects from before the war. Its speed is likewise limited, the lowest of any fifty ton tank built after the war.
