The GMC Yukon Hybrid still looks like a standard GMC Yukon full-size sport utility vehicle. That means it's a tall, upright, and slab-sided vehicle based on a truck chassis. The GMC Yukon was last redesigned for 2008, and aside from its front-end styling, it is largely similar to the Chevrolet Tahoe, with which it shares its platform. But the Hybrid model has several subtle modifications that improve aerodynamics and reduce weight, along with a number of Hybrid badges. The top-of-the-line Denali model, reviewed separately, adds exclusive and more elegant interior and exterior touches to dress up the basic Yukon. Last year, a Yukon Denali Hybrid model was added to give the bucks-up version the option of better fuel efficiency. Even the standard Tahoe Hybrid, however, is trimmed somewhat better than its non-hybrid Tahoe counterpart.
ForbesAutos says the 2010 GMC Yukon Hybrid shares the regular Yukon's "unashamedly big and broad-shouldered" styling, though it does get a new, "brash front-end treatment." Cars.com concludes that "few onlookers will mistake the Yukon Hybrid for anything but a Yukon." Motor Trend notes that "the grille is slightly larger for better cooling," along with tapered running boards "to decrease wind resistance." Also, "the roof rack rails are eliminated" to cut drag. Kelley Blue Book adds that "a lower air dam that reduces drag" replaces the "traditional fog lamps and tow hook openings," and "wide openings in the grille" help "cool the advanced hybrid power electronics." Cars.com also cites "lower side cladding and unique 18-inch wheels" that help to reduce drag, working with the hybrid system to improve fuel economy. Finally, Kelley Blue Book points out that the Yukon Hybrids "delete the standard roof rack side rails" and replace the steel rear liftgate "with a one-piece aluminum door featuring a fixed glass window," while "an extended rear spoiler improves aerodynamics, as do the sharp-edged D-pillars."
The interior of the 2010 Yukon Hybrid is universally appreciated by reviewers. On the revised center stack, Cars.com notes that the Yukon Hybrid's "center display screen incorporates an animation showing the flow of power through the hybrid drivetrain" and points out that "the gauges include a gas mileage meter." Kelley Blue Book adds that "a revised instrument cluster plays home to a unique tachometer designed to inform the driver when the Auto Stop feature engages." Edmunds calls the 2010 GMC Yukon Hybrid's "handsome cabin" one of its most appealing aspects, while ForbesAutos says that the "GMC Yukon Hybrid's handsome interior includes a two-tone instrument panel with LED-backlit instrumentation" and "chrome trim."
