The Car Connection's Take
TCC Rating
7.8
8.0
TCC’s Bottom Line
A sporty yet smooth driving feel, quiet interior, and top-tier safety all add up to a lot of appeal for the 2015 Acura RDX, although its lack of features and flair stop it short of greatness. The 2015 Infiniti QX50 isn't as useful as many of its competitors, but it's more fun to drive–and comes with a handsome, well-appointed interior.
