TCC’s Bottom Line

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.

TCC Likes

Relative value compared to some
Big back seat
Whisper-quiet ride

Handling and poise
Voluptuous sheet metal
Comfortable, supportive front seats

TCC Dislikes

…but may put some to sleep
Poor fuel economy
Lacking some safety tech

F Sport's stiffer ride
Responsiveness in GS 300
Mediocre mileage for GS 350
