The verdict: GM has been wowing us with its redesigned 2021 three-row SUV siblings, the Chevrolet Suburban, Cadillac Escalade (which we named Cars.com 2021 Luxury Car of the Year) and now the GMC Yukon, a downright luxurious SUV in its own right. Our test vehicle, a Yukon AT4, had captain’s chairs in the second row and a three-seat bench in the third row.
