The Yukon added some nice options for 2003 that include enhanced Bose audio, a DVD system, and push-button controls in the steering wheel. Overall, this full-size SUV has 7 trims: Base, Base 4WD, SLE, SLE 4WD, SLT, SLT 4WD, and Denali 4WD. The Yukon offers 3 V8 powertrains: a 4.8 L, 275 hp, 4.8 L, 285 hp, and 6.0 L, 325 hp. Gas mileage averages out to around 14 mpg in the city and 19 on the highway. All trims have 4 doors and seat anywhere from 6 to 9, depending on which variation you choose. Max towing capacity can go anywhere from around 8000 lbs. up to nearly 9000 lbs. Cargo capacity reaches up to 105 cubic feet if you fold down the second row and take out the third. As with most Yukons, the 2003 edition gets high marks for its engines and passenger room. However, the '03 Yukon could use better exterior and interior materials. That said, this SUV delivers pretty much everything you'd expect from a quality domestic model and a little more.
