Among full-size SUVs nothing stands above the GMC Yukon, not in its combination of size, power, luxury, capabilities and commanding presence. Available in Yukon and the longer Yukon XL, and in trim levels of SLE, fully-outfitted SLT and range-topping Denali, the Yukon gets its top billing the old-fashioned way: It earned it. If you need any more convincing, consider the Denali. It retains its unmatched 6.2-liter 420-horsepower V8 and adds an astonishing level of comfort, convenience, luxury and technology features; there has never been a full-size SUV quite like this. And the customers agree, with about 60 percent of Yukon buyers being seduced by the Denali's undeniable charms. If you're looking for the top of the SUV category, this is it.
