2010 GMC Sierra Denali HD- Sierra's Topline Model

Off-Road / 2 Comments

For 2010, the GMC Sierra Denali remains the Sierra's topline model. Available as a crew cab with either rear or all-wheel drive, the engine of choice is the 6.2-liter L9H V8 with 403 horsepower. As with the rest of the 2010 Sierra lineup, the interior features side curtain airbags, seat mounted side airbags, and a now-standard USB port on all radios. The interior of the Denali has long been considered luxurious and this is keeping in line with that notion.

The interior door trim has been revised as well, and assisting the Sierra in the handling and stability department is the StabiliTrak electronic control system. For the exterior, the Sierra Denali HD is now sporting a new exterior color, Carbon Black Metallic. The fuel mileage has also improved on the Denali, but not much. According to EPA fuel ratings, the Denali HD can achieve 13 miles per gallon in the city and 19 miles per gallon on the highway.
