The 2019 Cadillac XT4 is available in three trim levels: Luxury, Premium Luxury and Sport. The base Luxury trim level doesn't quite come with all the features you might expect, but nonetheless it's decently equipped. Feature highlights include 18-inch wheels, LED headlights, power-adjustable front seats, simulated leather upholstery, keyless entry and ignition, remote start, and dual-zone climate control. Infotainment is handled by 8-inch touchscreen, Near Field Communications for easy Bluetooth connections, Android Auto and Apple CarPlay, a 4G LTE Wi-Fi hotspot, four USB outlets (including one Type-C), and a seven-speaker sound system with satellite radio. Stepping up to the Premium Luxury nets you automatic wipers, auto-dimming mirrors, a power liftgate, a rear cargo shade, driver-seat memory settings, ambient interior lighting and added drive safety aids, including front and rear parking sensors, blind-spot monitoring, and a seat that vibrates to alert the driver.
