No, the Cadillac XT5 is not the same as the GMC Acadia. The GMC Acadia is a midsize SUV with standard three-row seating capacity, while the Cadillac XT5 is a compact luxury SUV sporting two rows of seats. If you need a third row, you can consider the GMC Acadia. But if you want to be treated to Cadillac luxury, opt for the new Cadillac XT5 instead.
