The Car Connection's Take

TCC Rating

8.4
8.0

TCC’s Bottom Line

The 2015 Acura RLX is an understated luxury full-sizer that puts emphasis on unique technical solutions instead of all-out style and flair. The 2015 Kia K900 reaches for the luxury stars--and grabs a little Lexus and old-school Cadillac, though it falls well short of Audi.
