Would you mind listing them? Because I sure couldn't come up with any.

I get the impression that you think that "harnessing" your power at one point will make the robot more powerful. This is simply not the case (darned physics ). In general terms, as long as all the motors are somehow connected to a wheel on the ground, it doesn't give you more power to have more or less wheels on the ground. Now, if you were considering having four motors driving instead of two, yes, that would give you more power. But if you wanted four motors driving two wheels as opposed to four motors driving four wheels, that wouldn't give you more power.
