New Sierra Denali delivers performance, fuel economy

The Sierra Denali is offered in 2WD and AWD configurations. It is powered by an exclusive 6.2L V-8 engine, rated at 403-horsepower (300 kW) and 417 lb.-ft. of torque (565 Nm).

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 help 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 Z85 suspension, four-wheel disc brakes, StabilTrak, 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 is available in three exterior colors: Onyx Black, Olympic White and Fine Silver Birch Metallic.

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. Denali models also feature a unique center console, enhanced interior bright work and detailed, highly finished embossed sill plates that greet passengers when they open any of the Sierra Denali's doors.

The unique center console has wood grain trim that conceals the lid and cupholder pockets, creating a more finished and refined appearance.

In addition to a full complement of standard amenities, Sierra Denali offers such exclusive features as an available heated steering wheel. Interior colors include all-Ebony and an exclusive Cocoa/Light Cashmere combination.

Standard features include rollover capable head curtain air bags, power-adjustable pedals, electrochromic (auto-dimming) inside mirror, dual-zone automatic climate control, rain-sensing automatic windshield wipers, remote starting system, EZ Lift Tailgate and Ultrasonic Rear Parking Assist.

From an entertainment standpoint, Sierra Denali comes standard with an AM/FM MP3-capable radio with a six-disc in-dash CD changer, Bose premium speaker sound system, rear-seat audio and XM Satellite Radio.

Optional features include the cargo management system, power-sliding rear window, roof rack, navigation radio system, power sunroof and a DVD-based rear-seat entertainment system.

Available later in the 2008 model year, the Sierra All Terrain builds on the dynamic Z71 Off Road package with a roster of stylish, refined and capable features that combine to create a unique truck that's ready for anything.

The All Terrain will be available on extended cab standard box and crew cab models in either 2WD or 4WD.
