Standard equipment for the base XTS includes 19-inch wheels, adaptive suspension dampers, rear air springs with automatic leveling, HID headlamps, LED taillamps, heated mirrors, rear parking sensors, keyless entry and ignition, remote start, dual-zone automatic climate control, eight-way power front seats (with power lumbar adjustment), a power tilt-and-telescoping steering wheel, leather seating surfaces, and 60/40-split folding rear seatbacks with a lockable cargo pass-through.
Standard technology features include Bluetooth phone and audio connectivity, a 4G LTE connection with Wi-Fi hot spot capability, an 8-inch color touchscreen user interface, Apple CarPlay and Android Auto smartphone integration, OnStar, voice controls and an eight-speaker Bose sound system with a CD player, satellite radio, HD radio, USB connectivity and an auxiliary audio input.
The XTS Luxury Collection adds dual-exhaust outlets in the rear fascia, illuminated door handles, rain-sensing wipers, power-folding mirrors, interior LED lighting, extended wood interior trim, a heated steering wheel, driver and front-passenger memory functions, heated and ventilated front seats, a navigation system, heated rear outboard seats, front and rear parking sensors, a rearview camera and an automated parallel-parking system (front-wheel-drive models only).
An optional Driver Awareness package for the Luxury Collection trim adds lane departure warning, lane departure prevention (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 Collection comes standard with the Driver Awareness package, and it adds adjustable thigh support for front passengers, automatic adaptive headlights, a reconfigurable color head-up display, an upgraded 12.3-inch, driver-configurable gauge cluster display, a 110-volt power outlet, a 14-speaker surround sound Bose audio system and tri-zone automatic climate control.
The V-Sport Premium adds 20-inch wheels and an electronic limited-slip differential, though it loses the automated parking system and lane departure prevention due to its standard all-wheel-drive configuration.
An optional Driver Assist package for the Premium Collection and V-Sport Premium adds adaptive cruise control and a forward collision mitigation system with automatic braking. A power rear-window sunshade and manual rear side-window sunshades are also available.
Both the Luxury and Premium Collections are eligible for a panoramic sunroof.
The Platinum Collection includes the above options as standard, adding special 20-inch wheels with chrome accents, unique exterior styling (including its own grille), a faux suede headliner, upgraded leather upholstery, extended leather trim (including the center console, door panels and instrument panel hood) and a deluxe rear armrest with audio and sunshade controls. The V-Sport Platinum is similarly equipped, including the chrome-accented wheels, but otherwise shares the V-Sport Premium's distinctions.
The Platinum Collection models also come standard with 22-way power-adjustable, massaging front seats that are optional on the Premium Collection.
The 2017 Cadillac XTS comes standard with front-wheel drive and a 3.6-liter V6 engine that produces 304 hp and 264 pound-feet of torque. A six-speed automatic transmission with paddle shifters is standard. All-wheel drive is available and can be identified by the moniker "XTS4."
In Edmunds testing, an XTS4 Platinum went from zero to 60 mph in 7.3 seconds, a second or so behind similarly priced and powered luxury sedans. EPA-estimated fuel economy is 22 mpg combined (18 city/28 highway) with front-wheel drive and 20 mpg combined (17 city/26 highway) with all-wheel drive.
If you want more pep, the V-Sport Premium and V-Sport Platinum trims come with a twin-turbocharged version of the 3.6-liter V6 that produces 410 hp and 369 lb-ft of torque. It requires premium-grade gasoline. All-wheel drive is standard with the turbo V6, as is a six-speed automatic.
We clocked an XTS V-Sport at 5.4 seconds from zero to 60 mph, which is about average for a premium luxury sedan with an upgraded engine. The EPA rates the V-Sport at 18 mpg combined (16 city/23 highway).
