The Cadillac XT6 is a luxury SUV that combines style with good on-road handling and a composed ride. Slotting between the XT5 and Escalade in Cadillac's lineup, the XT6 features three rows to comfortably seat seven passengers, but lacks the ample third row space and cargo volume of the larger Escalade. The sole available engine is a 3.6-liter V6 that sends 310 hp to either the front or all wheels, and thanks to cylinder deactivation and mated to a nine-speed automatic remains relatively frugal for a vehicle this size.
