Two different body styles both have plenty of room for five or six passengers in the 2010 Yukon-and the stretched Yukon XL can carry an astounding amount of stuff.
The standard 2010 GMC Yukon rides on a 116-inch wheelbase, with an overall length of 202 inches. The extended-wheelbase Yukons add about 20 inches of overall length and 14 inches of wheelbase, which goes to a more accessible third row and larger cargo capacity in back. That brings its total length up to 222 inches (more than 18 feet), which many city dwellers or even those who frequent shopping malls might find too large to fit easily into conventional parking spaces.
With "rugged and luxurious transportation for up to" nine passengers, according to Edmunds, the Yukon offers several seating configurations. All offer "great passenger comfort," Kelley Blue Book says, and a "spacious interior." In front, the seats are very generously sized and supportive, with a good view of the road ahead. The first two rows can be equipped with bench seats or buckets (called captain's chairs here); a third-row bench seat is standard on Yukon XL models and available on the Yukon. Kelley Blue Book states that the "front seats gain fore-and-aft and recline travel and second-row seats recline further, too." In the middle row, Edmunds finds that "the plush seats" offer "plenty of back and under-thigh support," while on the XL model, "the third row offers 34.9 inches of legroom, nearly 10 inches more than that of a standard Yukon." A third-row bench seat has seating for up to three more in back, but in any Yukon, the third-row seat is a bit difficult to clamber into. Cars.com notes "third-row passengers sacrifice headroom and legroom."
Denali models have slightly different seating. The standard configuration is for seven, spread across two front buckets, two middle-row captain's chairs, and a three-person rear bench seat. A second-row bench seat is a no-charge option. ConsumerGuide observes the "front seats are supportive," with "ample headroom and legroom" and "a power tilt feature [for] the steering column." Kelley Blue Book reports the middle row offers "power fold-and-flip second-row seats," but they warn that, "unlike the Ford Expedition, Dodge Durango and Nissan Armada, none of GM's full-size SUVs feature a fold-flat third-row seat," and point out "this could be the Yukon's deal-breaker." The seat itself-as in the standard Yukon-is cramped. ConsumerGuide says the "low-to-floor 3rd row cushion forces knees-up discomfort for anyone larger than toddler size."
Cargo capacity, even in the short-wheelbase Yukon, is massive-depending on the presence of the third-row seat, which robs the Yukon of some of its vast expanses. In the standard-length version, there's very little space behind the last row. It has 108.9 cubic feet with the second and third rows down-which "rivals that of the Ford Expedition and bests most other competitors," Edmunds says"-but just 16.9 cubic feet with the third-row seat raised. The XL fares much better, of course. With the third row removed and the second row folded, the Yukon XL has a huge 137.2 cubic feet of cargo space-"that's compared to the Expedition EL's 130.8 cubic feet," Cars.com explains-and there's still respectable room for cargo with people in all three rows. With the third row in place, the Yukon XL and Denali XL have cargo volumes of "45.8 cubic feet behind the third row," Cars.com reports. Inside the cabin, storage space abounds as well; for example, Kelley Blue Book proclaims that "the Yukon's gloveboxes are huge."
Throughout the Yukon's cabin, details and build quality impress reviewers from around the Web. Edmunds notes the "high-quality fit and finish" throughout the interior. Cars.com points out the "high-quality fixtures include flush-mounted controls, low-gloss materials and chrome instrument surrounds." Compared to both the domestic and foreign competition, Edmunds says the Yukon's fit and finish "place it among the class leaders." Edmunds also thinks "the quietness of the cabin at speed is eerie for something that looks as aerodynamic as a brick," while ConsumerGuide asserts noise suppression is "impressive for a large SUV."
