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 V-8 with 403 horsepower and 417 pound-feet of torque.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 door trim has been revised, and assisting the Sierra in the handling and stability department is the StabiliTrak electronic control system.
One new exterior color, Carbon Black Metallic, will be joining Onyx Black and Summit White on the Sierra Denali’s order forms.Source: General Motors
