As a replacement for the plush DTS flagship, the XTS falls short. It handles better, but the ride is jittery and feels very ordinary for a luxury car. Further, the 3.6-liter V6 sounds coarse when prodded. The XTS does have a quiet, posh, and beautifully finished interior however, and the seats are very comfortable. But the touch-activated CUE infotainment interface is unintuitive and frustrating to use, and the high rear deck impedes the view aft. Various safety systems, including lane-departure detection, will vibrate the driver's seat as a warning. A high-performance Vsport version with a twin-turbo V6 is also available, and all-wheel drive is an option on all but the base-trim versions.
