TCC’s Bottom Line
The 2012 Audi Q7 has what upscale suburban families want: a lavish interior, a cabin full of premium features, and performance and ride that are very carlike--plus serious towing ability if and when you need it. With rugged styling, fairly nimble handling and diesel economy, the 2012 Mercedes-Benz GL-Class can charm the mud right off a Land Rover Range Rover. The 2012 Porsche Cayenne comes equipped to take on a rugged trail, the racetrack, and child ferrying, all in the same day.
