GMC has unveiled new 2011 Sierra Denali HD, which leads the redesigned lineup of 2011 Sierra 2500HD and 3500HD trucks that are expected to go on sale in early summer.

The company said that the Sierra HD's new 6.6L Duramax turbo diesel delivers 397HP (296kW) at 3,000rpm and 765lb-ft of torque (1,037Nm) at 1,600rpm.

GMC said that the new Sierra Denali HD comes on the 2500HD chassis, in a 4WD crew cab standard box configuration. It includes a Vortec 6.0L gas V-8/six-speed automatic powertrain and the new Duramax 6.6L turbo diesel/Allison 1000 six-speed transmission powertrain. It offers a chrome grille with round air inlets on the outside, along with body-color bumpers, chrome door handles, chrome accents and 18-inch and 20-inch polished forged aluminum wheels.

According to GMC, the new Sierra Denali HD features an increased towing capability and payload; five of the 12 3500HD models offer a payload capability greater than 6,000 pounds and thirteen of the 22 2500HD models offer a payload capability greater than 3,100 pounds.

In addition, Sierra Denali HD features larger gas tank and fuel economy enhancements that allow up to 680 miles between fill-ups with 6.6L Duramax turbo diesel; a new 'smart' exhaust brake feature; and new technology including OnStar and turn-by-turn navigation, available mobile WiFi, USB connectivity, Bluetooth connectivity, and XM satellite radio.

The company said that the new Sierra Denali HD comes with control features such as, trailer sway control, integrated trailer brake control, hill start assist, automatic grade braking, intelligent brake assist and larger brakes.

Lisa Hutchinson, product marketing director of GMC, said: “The new Sierra Denali HD is the latest expression of GMC's Denali philosophy of blending capability with premium features and styling.

“It is a premium tool that offers many comfort and infotainment features, along with a maximum towing capacity of 15,600 pounds with the segment's most powerful diesel, that's enough to tow a 34-foot-long, three-axle travel trailer.”
