FWIW I have never ran out of torque, not once. I have pulled buggies out of the muck at just off idle and I climb hills that I really shouldn't have due to the real concern of death. With that said my tires do not have tight tread to hold mud and they are skinny, wide tires would eat more power in the soup than these. If you look at the actual power to the ground by something like a 2008 Teryx with a carb or a Rhino etc..and that snowmobile/golf cart belt technology the P5 has less parasitic waste of power and more usable power down low due to less slippage in the drive line. And those buggies have much larger engines.
EDIT to add, the power to weight ratio of the P5 compared to the 700 is the same.
