Total vaporware. Their claimed performance is just ridiculous - they propose a massive hauler truck with 4x the battery capacity of a Tesla Model S while getting...5x the range? and 4x the HP.
It is not a fully electric system like the Model S. The drive system is electric but the electricity itself comes from an onboard CNG turbine. The battery just acts as a buffer and place to store regenerative breaking energy.
It's a natural gas powered hybrid, not a pure electric.
400KW turbine on the back is what provides the added range.
