Think of the Yukon Denali as a more luxurious Yukon. The Denali got a major makeover that includes a prominent new chrome grille, re-designed head and taillights, and fresh new interior with wood trim. Unlike other GMC pickup trucks, you only get two trims: the AWD and XL AWD. Either way, you can't go wrong when you've got a 6.2 L, 380 hp V8 engine with 6 speed automatic transmission., , As for fuel consumption, expect to get 13 mpg in the city and 19 on the highway. Both trims have 4 doors and seat 8. The Denali AWD gives you 16.9 cubic feet of cargo space that expands to 109 when you fold down the second row and take out the third. As befits its name the Denali XL AWD starts at 45.8 cubic feet and expands to 137 after a little manual labor., , Overall, drivers like the extra luxury that the Denali adds to the already comfortable yet powerful Yukon lineup. the Yukon Denali can officially declare a successful re-introduction to the domestic pickup truck market.
