The Platinum and Platinum V-Sport models are further beautified by unique grilles, whereas illuminated door handles are standard on the Luxury, Premium Luxury, and Platinum models. Cadillac performed minor revisions to the chassis as well, starting with the choice of tires and wheel designs (19- and 20-inch). Additionally, NVH levels were also improved thanks, in particular, to an increased use of sound insulators.
CUE infotainment, even in its most basic form, has been upgraded to offer better graphics, faster response time, and smartphone-inspired navigation. With 18 cubic feet to its name, the 2018 Cadillac XTS also happens to offer more trunk capacity than most of its segment rivals. The Chrysler 300 and Mercedes-Benz S-Class, for example, make do with 16 cubic feet.
Other than the standard 3.6-liter V6, there’s a twin-turbocharged engine available in the lineup. Exclusive to the XTS V-Sport, the force-fed six-cylinder develops 410 horsepower and 369 pound-feet of torque. What’s not so great about the redesigned XTS is the transmission, which boasts the same six ratios as ever. By comparison, the CT6 and XT5 brag with eight-speed boxes.
A couple of small updates were brought to the interior as well, but more importantly, the XTS is safer than the model it succeeds. For 2018, the Driver Awareness Package features Low Speed Automatic Braking, Following Distance Indicators, and Lane Change Alert. For some reason or other, Automatic Parking Assist is limited to front-wheel-drive models.
