Not to mention the slight aversion to water that electric motors DON'T have.

The thing is that an electric off-road vehicle would have a motor on each wheel hub, and each one would have 100% of it's power available from 0 RPM to full speed. The idea of "traction" being important is where this becomes critical. Each wheel will be able to sense slippage and reduce speed to maintain maximum traction while simultaneously the power to each wheel can be applied in a controlled manner by the computer so that each wheel's torque is increased or decreased in a smooth manner to avoid "breaking loose". If you think of the way you apply the clutch to a internal combustion car slowly and gradually to avoid spinning the tires and then translate that into individual control like that for each wheel automatically by the computer then you can see where an electric offroad vehicle would be awesome!
