The 2018 Cadillac XTS delivers on the brand's traditional strengths: a smooth ride quality, a quiet cabin, a big back seat and classy styling. It should be appealing if you value these qualities and don't need a bunch of performance capability in your luxury sedan.
That's not to say the XTS doesn't have any hustle. Although we've found the standard V6 struggles to launch the big sedan with any urgency, the 304-horsepower engine does fine once up to speed. We'd love to steer everyone into the top V-Sport trim and the 410-horsepower turbo V6 engine that comes with it, but that fully loaded model might be overkill for most drivers. Fast but perhaps not practical.
That's why it's hard to go wrong with any of the XTS trims, whether you just want a standard set of luxury and tech features or more modern conveniences and all-wheel drive. For 2018, the XTS gets a more refined cabin environment, with increased sound deadening and upgraded seats and a few exterior freshening tweaks. Whichever XTS you choose, you'll get a sharp luxury sedan with loads of room, especially in back, and a comfortable, quiet ride.
trim levels & features
The 2018 Cadillac XTS is a five-passenger large sedan available in four trim levels: base, Luxury, Premium Luxury and Platinum. The turbocharged V-Sport variant is only offered in Platinum trim. The base trim (called simply XTS) comes nicely equipped with a fair amount of luxury and tech, while the Luxury amps things up with features like heated front and rear seats and a navigation system. The Premium Luxury adds more desirable tech features, and the Platinum loads up with the best of the Cadillac catalog. The V-Sport Platinum also comes fully loaded but adds a 410-hp V6 engine.
The XTS comes equipped with a 3.6-liter V6 engine (304 horsepower, 264 pound-feet of torque) paired with a six-speed automatic transmission and front-wheel drive. All-wheel drive is available on all but the base trim.
Standard features on the base model include 19-inch wheels, LED headlights, heated side mirrors, rear parking sensors, keyless ignition and entry, dual-zone automatic climate control, power-adjustable front seats, leather upholstery, and 60/40-split folding rear seats with a cargo pass-through.
Tech features include a rearview camera, Bluetooth, OnStar (includes a 4G LTE data connection and Wi-Fi hotspot), an 8-inch touchscreen, Apple CarPlay and Android Auto smartphone integration, and an eight-speaker Bose audio system with satellite radio.
The Luxury trim adds automatic wipers, ambient interior lighting, extended wood trim, a heated steering wheel, heated and ventilated front seats, heated rear seats, a navigation system, front and rear parking sensors, and an automatic parking system (front-wheel-drive models only).
An optional Driver Awareness package for the Luxury trim adds lane departure warning, lane keeping assist (FWD only), blind-spot monitoring, rear cross-traffic alert, forward collision alert, a vibrating safety-alert driver seat and a surround-view camera system.
The Premium Luxury comes standard with the Driver Awareness package and adds 20-inch wheels, an adaptive suspension, adjustable front-seat thigh support, adaptive headlights, a head-up display, an upgraded driver-configurable gauge cluster display, a 110-volt power outlet, front-seat memory settings, a 14-speaker Bose surround-sound audio system, and tri-zone automatic climate control.
Moving up to the Platinum adds an electronic limited-slip differential, a panoramic sunroof, a simulated-suede headliner, upgraded leather upholstery, extended leather trim (center console, dash panel), 22-way power-adjustable massaging front seats, and a deluxe rear armrest with audio and sunshade controls. Advanced driver aids include adaptive cruise control and forward collision mitigation with automatic emergency braking
The V-Sport Platinum is, no surprise, equipped almost identically to the regular Platinum trim, with the exception of a turbocharged 3.6-liter V6 engine underhood (410 hp, 369 lb-ft). All-wheel drive comes standard with the V-Sport, as does a six-speed automatic transmission.
Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our full test of the 2014 Cadillac XTS V-Sport Premium (turbo 3.6L V6 | 6-speed automatic | AWD).
NOTE: Since this test was conducted, the current XTS has added tech features that include a Wi-Fi hotspot, wireless smartphone charging and Apple CarPlay/Android Auto. Our findings remain broadly applicable to this year's XTS.
