The 2007 GMC Yukon XL, in its 3rd generation, is a workhorse full-size SUV boasting a roomy cabin, robust towing capacity, and wide range of trims. It is available in both rear-wheel and four-wheel drive configurations. Engine options include a 5.3L V8 with 320 horsepower or a beefier 6.0L V8 pushing out 352 horsepower, mated to a 4-speed automatic transmission. The Yukon XL comes in three trim levels - SLE, SLT, and Denali. Safety features cover antilock disc brakes, stability control, and a full suite of airbags. Inside, the in-dash CD/MP3 player and optional navigation system highlight the tech features for the year. While not offering the fuel-efficiency of lighter SUVs, the 2007 Yukon XL impresses with its blend of comfort, power, and utility.
