2011 GMC Sierra HD Introduced, Denali HD Trim Added

Just a month ago, the 2011 Chevrolet Silverado HD was revealed at the Chicago auto show. No big surprise here, The General has followed up with its GMC variant, the Sierra HD. Since the two are identical under the sheetmetal, we won’t go into too much detail (you can read about all the same improvements here ). The biggest news for the Sierra HD is the addition of an upscale Denali trim package and newly exposed—and massive— power figures from the revised 6.6-liter Duramax diesel. This marks the first time the Denali package has been offered on GMC’s heavy-duty pickup line. The package is all appearance, taking on the unique Denali chrome grille, body-colored bumpers, chrome accents and door handles, as well as 18- and 20-inch polished aluminum wheels. Inside, brushed-aluminum trim, power-adjustable pedals and seats, and a Bose sound system all come standard, while a heated steering wheel, and heated and

cooled leather seats are available as options. The Denali package is offered only on the four-wheel-drive 2500-series crew cab standard box configuration which will allow bed payloads of up to 2959 pounds and a maximum tow rating of 15,600 pounds with a fifth-wheel hitch. Color choices are limited to black, Stealth Gray, and white. Beating the 2011 Ford Super Duty by seven horsepower and 30 lb-ft of torque, the updated optional diesel engine now puts out 397 hp and a staggering 765 lb-ft of torque. An improved Allison six-speed automatic transmission will disperse all that power when the HDs goes on sale early this summer.
