TCC’s Bottom Line
There's much to love about the 2014 Audi Q7 and few if any failings; it does everything a three-row crossover vehicle should do, with great elegance and sophistication—and skips the faux-rugged nonsense. The 2014 Mercedes-Benz GL may be an expensive way to haul the family around, but it has excellent driving manners and some very sophisticated safety technology, too. Yes, Porsche does make a family car, and this is it; the 2014 Cayenne runs the gamut from sporty errand mule to track-worthy sports SUV, with some interesting green options in between.
