The Car Connection's Take
TCC Rating
8.4
8.2
TCC’s Bottom Line
The 2015 Kia Optima meets all your needs in a sensible four-door sedan, but exceeds expectations for more flair and features. The stunning exterior of the 2015 Mazda 6 isn't leading you on; with an athletic driving experience and a lot of sophistication for the money, this a charming sedan with a surprisingly frugal side.
