2008 GMC Yukon XL Review

The perfect vehicle for large families and those with heavy-duty towing needs.

Reviewed by Automotive on


The 2008 GMC Yukon XL classifies as a four-door, full-size SUV with the ability to play many roles. It measures 20 inches longer than the standard Yukon and seats six to nine passengers depending on the seating configuration. In addition, those passengers sit in comfort and plenty of room remains for cargo. The XL even provides decent legroom in the third row. In addition, it includes a vast array of mechanical, size, weight, and cosmetic choices to streamline the Yukon XL to match most requirements.

In addition, it meets the domestic requirements for a seating capacity of up to nine passengers and all their stuff such as baseball gear or camping gear. Additionally, it has the upscale appearance and comfort for around-town driving or long journeys.

The XL comes in the 1500 and 2500. The SLE trim level can be upgraded with an SLT package. The Denali is a top-shelf level trim only available on the 1500.

What's New

Side-curtain airbags become standard on all models of the 2008 GMC Yukon XL. A six-speed automatic transmission and stability control also become standard on the 2500. Turn-by-turn navigation adds to the OnStar in the SLT and Denali.


Even though the XL is a huge vehicle, it has a sleek and clean appearance with nicely shaped curves. The side moldings and door handles are body colored and it leaves out excessive chrome. Integrated running boards do not stand out and have a grip coat. Behind the C-pillar sits an enormous tinted glass. The huge square headlights sit over the front bumper fascia. A convenient rear window opens separately. The light weight of the aluminum liftgate makes it easier to open and close.

The SLE comes standard with 17-inch wheels, and the Denali trim bumps up to 18-inch wheels. Twenty-inch wheels, a power liftgate, and a sunroof provide options.


It offers abundant head and legroom in the front in addition to having comfortable seats that ride high, overlooking the road. The second-row seating feels roomy as well, especially with bucket seats, and has its own console. In addition, it has separate audio controls and an optional DVD screen that drops down from the headliner. Another optional power feature folds down the second-row seats with the push of a button. The third row accommodates either two or three passengers depending on the chosen package.

The pedals can be adjusted with the push of a button.The center stack and instrument panel look upscale, elegant, and worthy of a high-end vehicle. The Denali looks more lavish with dark wood trim and a leather-wrapped steering wheel. As with the exterior, the instrumentation and switchgear are clean and simple. The center console is enormous with deep storage. In addition, the console holds two removable cup holders and come in each door pocket. The 2008 GMC Yukon XL also includes a user-friendly navigation system.

Shifting into reverse activates the optional rear-view camera. The rear-view camera provides a convenient option and safety feature.

Performance & Handling

The 2008 GMC Yukon XL serves as a perfect towing vehicle and if you need extra towing power, the optional 366-horsepower, six-liter V-8 makes it a breeze to climb steep grades. If you need even more, the 2500 makes a good choice, and the Denali XL has a Corvette-based, 6.2-liter engine. For pulling a big load, all Yukon XLs have a Tow/Haul mode that reduces the upshifting and down shifting. It also enables quicker shifting to prevent the transmission from over working.


The XL includes an extensive list of standard features, which consists of stability control with a rollover sensor, front and rear ventilated anti-lock disc brakes, electronic brakeforce distribution, side-curtain airbags, and OnStar. In addition, it features a remote anti-theft alarm system, daytime running lights, and auto delay-off and dusk-sensing headlights. Other standard safety features include an engine immobilizer, a post-collision safety system, and tire-pressure monitoring.
