GMC Yukon I (GMT400) gallery (1991–1999)
The first generation of the full-size body-on-frame SUV that succeeded the GMC Jimmy.
The first generation of the GMC Yukon was introduced for the 1992 model year (production starting in 1991) on General Motors' GMT400 platform, originally replacing the long-running full-size GMC Jimmy as a two-door SUV. A five-door four-door version arrived in 1995, vastly increasing the vehicle's market appeal. Under the hood, the Yukon was primarily powered by a 5.7-liter V8 engine (initially the TBI L05, later upgraded to the multi-point Vortec 5700 L31 producing 255 hp) along with a 6.5-liter turbocharged Detroit Diesel V8. Power was managed through robust 4-speed automatic transmissions (4L60-E or 4L80-E), though rare early models were available with a 5-speed manual. Drivetrain options included rear-wheel drive and part-time four-wheel drive with shift-on-the-fly transfer cases. In 1998, GMC introduced the flagship luxury Yukon Denali trim. The model was predominantly sold across North America and the Middle East.
