It is just like an Abrams except the turbine engine has been dumped in favor of a diesel-electric hybrid. It uses fuel at 50% the rate of the M1A with the same performance. Using an unmanned turret eliminates the bulky mechanisms and a lot of electrical slip rings. The crew is safer because the armor can be thicker and the ammo is outside of the crew compartment. Many drive components have been eliminated due to the use of electric drive motors, increasing the weight allotment toward more armor.
It is a good design.
