Each wheel has its own engine, independently controlled by software. The "improved diff-lock effect" should result in stupendous capability. And, with all torque instantly available, only the quality of the rubber and the skill of the driver could adversely affect traction. When configured correctly, this vehicle will outdo anything else, as proven by the classic inventor of the electric wheel, the late R.G. (Bob) Le Tourneau, who also invented the bulldozer and much else. They built nuclear-powered rubber tyred snow trains for use in the Arctic. You can find it online and on YouTube. Many earthmoving devices were Diesel-electric with electric motors in the wheels. Sorry, Volvo, you didn't invent that.
