Hybrids and off-roading rarely are available in the same package, so the segment is not very broad. The Volkswagen Touareg hybrid provides a way to reduce one's environmental footprint and still enjoy off-road capability for $8,000 cheaper than a Porsche Cayenne.
The TDI Touareg is no slouch for fuel economy-- it is capable of 28 mpg on the highway and makes over 400 lb-feet of torque and features the same off-road capability and 7700 lbs of towing ability for less than $47,000.
