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 outruns most of the 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. Sport is the top-of-the-lineup for the XT4. It 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.
