2008 GMC Models

Though gas mileage ratings for GM's new full-size SUVs are impressive among their competitive set, they aren't likely to bring smiles to anyone at the pump; competitors aside, their combined ratings still linger in the teens. That changes with the 2008 Yukon Hybrid, a twin to the upcoming Chevrolet Tahoe Hybrid that promises a 25 percent improvement in overall gas mileage. Both models are expected to hit showrooms sometime in 2007.  

Introduced for 2007, the Acadia was GMC's first crossover and shares design cues with the brand's full-size SUVs: the Yukon and Yukon XL. It has a tapered roof line and rear spoiler and features wide rear doors for an easier step-in height. Competitors include the Hyundai Veracruz and Mazda CX-9. 

GMC introduced the Canyon pickup truck for the 2004 model year. Designed from the ground up, the Canyon is similar to Chevrolet's Colorado pickup. Both were larger than the previous compact models they replaced — the GMC Sonoma and Chevrolet S-10. Competitors include the Ford Ranger and Toyota Tacoma. 

GMC revived the Envoy name for 2002 on a brand-new midsize model related to the Chevrolet TrailBlazer. For 2008, all trim levels of the five-seat Envoy have standard side curtain airbags and XM Satellite Radio. Competitors include the Ford Explorer, Jeep Grand Cherokee and Nissan Pathfinder. 

For 2008, a tire pressure monitoring system is standard on GMC's full-size van, and passenger van models get standard side curtain airbags. Driver controls have been redesigned, too: new equipment includes the steering wheel, gauges, ventilation system controls, stereo and cloth seats. Competitors include the Dodge Sprinter and Ford E-Series.

When it was redesigned and reengineered for 2007, the Sierra's major changes included exterior restyling, improved interior quality, roomier cabins, higher maximum towing capacity and improved gas mileage. The Denali got a larger engine and six-speed transmission, so there are few changes for 2008. Safety options include side curtain airbags and an electronic stability system. Competitors include the Dodge Ram, Ford F-150, Nissan Titan and Toyota Tundra.

Slotting in price and equipment between the Chevrolet Tahoe and Cadillac Escalade, the GMC Yukon is the middle child among the sport utility vehicles on General Motors' full-size SUV platform. Competitors include the Chrysler Aspen, Ford Expedition, Nissan Armada and Toyota Sequoia. 

GMC's Yukon XL is the brand's flagship sport utility vehicle, and it underwent a complete redesign for 2007. Available in base SLE, SLT and top-of-the-line Denali trim levels, the Yukon XL is available with a choice of V-8 engines, some of which feature fuel management systems that deactivate four cylinders during low-load situations. According to the company, this technology can improve fuel economy by about 10 percent. Competitors include the Ford Expedition EL, Nissan Armada and Toyota Sequoia.
