Cadillac's metamorphosis into a modern luxury brand continues to unfold, with the latest addition to the lineup introducing a true flagship model. This is the first ever CT6. Though Cadillac already offers a large, turbocharged sedan with over 400 horsepower and available all-wheel drive, the CT6 evolves the premise of the XTS by introducing a new, lightweight, rear-wheel drive architecture with a significantly longer wheelbase lending to more elegant and classic big car proportions. But this isn’t your grandfather’s Deville – far from it. The CT6 possesses modern design, robust technology and performance attributes shaving countless gray hairs from the head of the average driver.
