 The engine problems with the Maybach were never overcome and lowering the hull to save weight, as was done for the final prototype, made it impossible to install a larger engine.Recognizing that the problem of combining excellent mobility with heavy armour was for the time being irresolvable, the AMX 50 project was terminated in 1959; the priority given to mobility demanded a new design concept, leading to the AMX 30, the lightest MBT of its time.Only in the early 1980s would France again attempt to combine heavy armour and armament in its tank designs, beginning with the later AMX 32 prototypes.
