All the same underpinnings are here: there's the Escalade's 403-horsepower, 6.2-liter V-8; its six-speed automatic transmission; and its full-time all-wheel drive system. Even its extra acoustic isolation measures to ensure a very quiet interior. But the Yukon Denali has neither the Escalade's name nor its super-shiny grille and perverse 22-inch wheel option.
The Denali, again like the Escalade, gets a host of lavish, exclusive materials and trims inside, along with a long list of luxury and convenience features, including tri-zone automatic climate control, a power-folding second-row seat, parking sensors, and remote starting.
Otherwise, the package is virtually the same as that of standard Yukons. Both standard-length Yukon and extended-length Yukon XL models are available in Denali trim. The Yukon Hybrid is—and even in Denali trim the Hybrid retains its 20/23-mpg ratings.
