The new GMC Yukon enters the 2021 model year sporting some fresh exterior styling and a completely new cabin design that makes provision for an optional power-sliding center console or a 40/20/20 split-folding front seat bench. A first for General Motors' full-size SUVs, GMC has also designed the Yukon with a new independent rear suspension kit that lowers the floor for more third-row passenger room. GMC has also made an all-new Active Response 4WD system available.
