2021 Cadillac XT4 Luxury

The XT4 is Cadillac's smallest SUV, a five-seat crossover that sits below the XT5 and competes with the BMW X1 and Audi Q3. The ride is comfortable on most roads, though the sportier trims firm things up noticeably over sharper bumps. Inside, the cabin uses quality materials and the rear seats offer decent space for adults, but cargo room trails some rivals. The Luxury is the trim most buyers start with, skipping the Sport's firmer suspension and darker trim for a more relaxed everyday feel. Its 2.0L I4 makes 237 horsepower and pairs with a nine-speed automatic, sending power to all four wheels; expect 24 mpg combined in mixed driving. The Luxury rides on smaller 18-inch wheels than the Premium Luxury, which softens the ride over rough pavement but trades some visual presence.
