Since the 1930's, GMC has been well-known for creating reliable trucks and SUVs. GMC trucks were also the upscale versions of the Chevrolet trucks, and the GMC Yukon balances above-average cargo room with comfortable passenger accommodations. Based on the GMT400 truck chassis, the Yukon is shorter than its cousin, the Chevrolet Suburban. People liked the GMC Yukon because it was agile, compact, powerful, and perfect for any urban or cross-country activities.
1992 to 1999: First Generation
The first GMC Yukon was a two-door SUV that debuted in 1992. Its GMT400 platform was a true truck chassis, and it's used in the Chevrolet Silverado full-sized pickup. It was powered by Chevrolet's 5.7-liter LO5 small-block V8 engine. A two-door and four-door model was also made available at that time. During this generation, a lot of upgrades were added to the Yukon which included revised side mirrors, a driver-side and passenger-side airbags, Vortec 5700 and Vortec 7400 engines, electronic 4WD shifting, illuminated entry, daytime running lights, and an improved steering system. Passenger and safety features like the PassLock security system, a programmable Homelink transmitter, and air-conditioning for rear seat passengers were also added.
2000 to 2006: Second Generation
Using the new GMT800 platform, the GMC Yukon's body construction was redesigned. The Yukon now sported softer lines to make it more aerodynamic. The Vortec 4800 and Vortec 5300 V8 engines replaced the old 5.7-liter small-block V8 engines. XM Satellite Radio, a Bose audio system, and a DVD entertainment system were some of the interior updates done on the GMC Yukon. In 2003, "StabiliTrak", GMC's stability control system and aFlexFuel engine was also introduced during this generation.
2007 to Present: Third Generation
An overall redesign of the GMC Yukon was based on the newer GMT900 platform. A different front fascia was given to the Yukon to differentiate it from its twin brother, the Chevrolet Tahoe. It now sports a monolithic grille and headlights. The Yukon's hood is now smoother with two slight curves on both sides. The GMC Yukon's angular design gave it a more elegant appearance. Thanks to its Active Fuel Management system, the Yukon's mileage is now at 21 to 22 miles per gallon. Three engine types are now powering the new generation of GMC Yukons: the Vortec 4800,Vortec 5300, and Vortec 6200 V8. In 2008, the GMC Yukon Hybrid was introduced to the mass market. It was designed with a gasoline/electric power train to achieve a 21 miles per gallon fuel consumption. The Yukon Hybrid also has an Electronic Variable Transmission (EVT) which allows it to switch, depending on the driving situation. With a 6,000 pound towing capacity, the GMC Yukon Hybrid beats all its competitors in this class.
