STORY

The GMC Yukon is a full-size body-on-frame SUV introduced for 1992, replacing the two-door GMC Jimmy and later becoming a four-door mainstay of GMC's lineup. Sharing its platform with the Chevrolet Tahoe, it offers V8 power, three-row seating, and the premium Denali trim that has become central to GMC's identity. It has progressed through the GMT400, GMT800, GMT900, K2XX, and current T1XX architectures.
