The Car Connection's Take
TCC Rating

TCC’s Bottom Line
Plush, safe, and well-equipped, the 2018 Genesis G80 remains a pure luxury sedan, even as rivals get increasingly sporty. The 2018 Kia K900 is a premium, luxury sedan without much of an identity. The 2018 Lexus GS is a worthy rival to its German foes in terms of luxury and handling, but its engine lineup is falling behind the competition.
