Based on the same GMT T1XX platform as the Silverado 1500, the Tahoe distinguishes itself by swapping that truck's live axle and leaf springs for an independent rear multilink suspension setup with coil springs, thus lowering the floor of the vehicle and creating more room in both the cargo area and the second-and third-row seats. The Tahoe expanded its size length to 210.7 inches, and the wheelbase to 120.9 inches while shortened down by 15 inches longer due to the rear wheelbase moving back by 5 inches, making it the largest SUV in the full-size length segment. It gains 11 cubic feet of cargo space behind the third row and 10 inches of third-row legroom.
