Even though some Full Hybrids have four-wheel-drive, they're not really designed to go off road. These 4WD vehicles are, in fact, sending power to the front wheels, but there's still some slippage, so you're not getting the kind of 4X4 you'd want to run over the Rubicon Trail.
Finally, while many people do tow trailers and cars behind different types of Hybrid vehicles, even Full Hybrids are not officially "rated for towing", therefore, they are not suitable for towing trailers over long distances.
According to Greg Wilson, who has his eye on the future of Hybrid trucks, alternative powertrains for trucks (including fuel cells, gas-electric Hybrids and diesel-electric hybrids) are only a few years away, but only Hybrid vehicles with an integrated starter generator have any real potential to match the hauling and towing performance of traditional big block engines.
