I know this is more detail, but, I'd guess this is using high efficiency fuel cell technology (at least two sets of cells, for redundancy), and that, baring the jump jets, this is basically an electrical vehicle, with direct drive of all six wheels (i.e. they all have their own electric motor, or equivalent).
It might be worth noting that loosing even two wheels, as long as they are not adjacent ones, means that it can keep going, though at reduced power, and it is possible (with some field engineering work) to move wheels around in an emergency. Might it even be possible to limp along with only three powered wheels, as long as there is a functioning fourth non-powered one left?
Looking at partial failure modes for vehicles can be useful, particularly for those writing stories using them. [grin]
