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 237 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, aluminum interior trim, power front seats, Cadillac's CUE infotainment system with an 8-inch color touchscreen, faux leather trim, 18-inch alloy wheels, LED headlamps, LED tail lamps and a rear park assist system. 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, wood trim, 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 rear park assist system, the Premium Luxury gets a lane change alert system, a rear cross-traffic alert system 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 decor 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 trailering package, a cold weather package, 20-inch wheels, a navigation system and a Bose surround sound system.
