2011 GMC Sierra Denali Crew Cab

(continued from above)

The engine is paired with the Hydra-Matic 6L80 six-speed automatic transmission. The six-speed automatic has a wide, 6.04:1 overall ratio - including two overdrive gears - that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter.

Sierra Denali also features a 9.5-inch rear axle (2WD) or 8.6-inch rear axle (AWD) with 3.42 gears and a locking rear differential. The specially tuned Z60 suspension, four-wheel disc brakes, StabiliTrak, skid plates and tow hooks are standard. Eighteen-inch polished aluminum wheels are standard, and unique 20-inch factory-installed chrome-finish aluminum wheels are available. The wheel designs are not shared with other Sierra models.

An iconic, Denali-specific chrome grille makes the truck instantly recognizable. Additional chrome trim and body-color bumpers further distinguish it. Sierra Denali also offers a unique combination of interior style and luxury, including standard nuance leather-covered front and rear seats, with heated, 12-way power-adjustable front seats, as well as leather trim throughout. A Denali-exclusive leather-wrapped steering wheel, which features wood grain accents and a host of auxiliary controls, is standard.
