As shown in the link above, only a fraction of power from each of four motors is being used. It's six of one and half a dozen of another. As far as I'm aware - and it's early yet so I may not be thinking straight - you'll never get more tractive force in the direction of travel than from what you'd get on a regular 2WD robot. The motors from which that power comes and in what ratio shift as your direction changes, but the cumulative output will remain the same.
