Besides some improvements to the transmission and internal parts, the 2002 GMC Yukon XL full-size SUV didn't do too much to detract from or improve upon its strong reputation in the automotive community. This 4 door workhorse comes in 13 trims and features 5.3 L and 6.0 L V8 powertrains packing around 300-320 hp. Think of the SLT as more luxurious than the SLE with standard features that include leather seats. Depending on which trim you choose, you'll have room to seat 8-9 passengers. Gas mileage across trims averages around 14 mpg in the city and 19 on the highway. Max towing capacity usually ranges from 8000-9000 lbs. with some trims reaching 12000. Cargo capacity comes out to a roomy 132 cubic feet. As usual, drivers like the '02 Yukon XL's roomy interior and powerful V8's. While its materials could use an upgrade, most reviewers agree that the Yukon XL gets the job done in more ways than one.
