2007-2008 GMC Yukon and Denali: Overview

Vehicle Highlights

GMC redesigned its large sport-utility vehicles for 2007, giving them more power, new features, and fresh styling. Regular Yukons and the longer-wheelbase Yukon XL models shared a new platform with the 2007 Cadillac Escalade, as well as the closely related Chevrolet Tahoe and Suburban. Yukon XL wagons were 14 inches longer in wheelbase than regular Yukons, measured 20 inches longer overall, and offered nearly 30 cubic feet more cargo volume. In addition to Chevrolet's Tahoe and Suburban, GMC competed against the Ford Expedition and Toyota Sequoia. Both Yukon and Yukon XL wagons came in SLE, SLT, and luxury Denali models. SLE and SLT versions offered a choice of rear-drive or four-wheel drive, which could be left engaged on dry pavement and included low-range gearing. Denali editions had specific styling and all-wheel drive, without low-range gearing. Standard on the rear-drive SLE model was a 295-horsepower, 4.8-liter V8. A 320-hp, 5.3-liter V8 was optional on that model and standard on other Yukons. Available on the Yukon XL was a 355-hp, 6.0-liter V8. Each of these engines used a four-speed automatic transmission and incorporated GM's Active Fuel Management cylinder deactivation system. Yukon Denalis got a 380-hp V8 and six-speed automatic transmission. Antilock braking and traction/antiskid control with rollover sensors were standard. GM's self-adjusting Autoride suspension was available on SLT models, and standard on Denalis. Curtain side airbags that covered all seating rows and included rollover deployment were standard on SLT and Denali, and optional for SLE. Yukons seated up to nine passengers. Denalis held up to eight. In all models, the second- and third-row seats folded and the third row was removable. As in GM's other large SUVs, a spring-release option could flip the second-row seats to provide third-row access. GM's OnStar assistance was standard. A power liftgate, remote engine start, rear-obstacle detection, and power-adjustable pedals were standard on Denali, and available on other models. DVD entertainment and a navigation system with rearview camera also were available.
