TCC’s Bottom Line
Though the 2015 Audi Q7 might show a little of its age, there are so few faults here that it's hard not to love this big SUV. The 2015 Mercedes-Benz GL-Class offers the most Mercedes luxury to the most people, with a pleasant ride and easy driving dynamics to boot. The 2015 Porsche Cayenne is no longer the only blasphemous off-roader in the Porsche family; this year, it gets improved powertrains and massaged looks in a familiar package.
