The Car Connection's Take
TCC Rating
8.0
8.0
TCC’s Bottom Line
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. The 2014 Acura RLX leaves the bold ambition to other brands; it's a studied update that delivers smoother looks, quicker performance, and better fuel economy, but no more excitement.
