The Cadillac XT4 is powered by a compact 2.0L 4-cylinder engine aided by a turbocharger. Though diminutive in size, the engine makes a stout 235 horsepower, feeding power to the front wheels via a 9-speed automatic transmission. Acceleration on the small SUV is so good that it easily outpaces most of the non-performance oriented vehicles in its class, yet still returns respectable mileage. Cadillac estimates that owners will see around 30 mpg on the freeway in front-wheel drive versions. The XT4 is available in three basic trims. The base trim is, fittingly for a Cadillac, simply dubbed "Luxury." Standard items on the Luxury trim include dual-zone automatic climate control, a remote starter, four USB ports, four 12-volt power sockets, SiriusXM satellite radio, aluminum interior trim, power front seats with adjustable lumbar support, Cadillac's CUE infotainment system with an 8-inch color touchscreen, Apple CarPlay and Android Auto, faux leather trim, 18-inch alloy wheels, LED headlamps and LED tail lamps. Standard safety systems include Forward Collision Alert warning and Front Pedestrian Braking and Rear Park Assist. The midlevel trim for the XT4 is called "Premium Luxury". Stepping up to Premium Luxury adds a powered liftgate, a memory function for the driver's seat, an auto-dimming mirror, additional ambient interior lighting, leather seating surfaces, power folding mirrors, illuminated exterior door handles with satin chrome accents and a more powerful suite of electronics for avoiding accidents. In addition to the Forward Collision Alert, the Premium Luxury gets a lane change alert system, a rear cross-traffic alert system, Front and Rear Park Assist and a safety alert seat. The top-of-the-line trim for the XT4 is dubbed "Sport." The Sport trim includes much of what was in the Premium Luxury trim, but adds LED turn signals, tinted taillights, a gloss black front grille, body colored door handles, carbon fiber décor, sport pedals, and a sportier steering wheel. Active suspension is also available on the XT4 Sport, making it better to handle than any other SUV out there. Options across the board include a sunroof, all-wheel drive, a cold weather package, 20-inch wheels, a navigation system, Bose surround sound system, wireless phone charger, heated and cooled seats, adaptive cruise control, following distance indicator, rear camera mirror, a trailering package, HD surround vision and reverse automatic braking.
