From job-ready Work Truck models to the unique combination of performance and luxury that is the Sierra Denali, the GMC Sierra lineup is one of the broadest in the industry. Powerful Vortec-based powertrains, backed by fuel-saving six-speed automatic transmissions, help Sierra models deliver among the industry's best fuel economy and performance - all with responsive ride and handling traits, and an exceptionally quiet driving experience.

A special Sierra XFE crew cab model is EPA-rated at 22 mpg on the highway. The Sierra Hybrid model returns for 2011, too, offering a 25-percent improvement in overall fuel economy, along with Sierra's traditional capabilities - including a 6,200-pound (2,812 kg) towing capacity. Please see the separate Sierra Hybrid release for complete details and specifications.

For 2011, changes to the Sierra lineup are include a new Gray Green Metallic exterior color, OnStar 9.0 and enhancements that reduce wind noise.

Sierra lineup

Sierra 1500 is available in several trim packages, including Work Truck, SL (crew cab only), SLE and SLT, along with 2WD and 4WD configurations. Three cab styles - regular, extended and crew cab - and three cargo box lengths - 5 foot 8 inches, 6 foot 6 inches and 8 foot - are offered. All models except the Work Truck model come with a distinctive chrome hood molding.

Standard equipment on the uplevel SLT models includes heavy-duty cooling; automatic locking rear differential; heavy-duty trailering package; 18-inch chrome-clad aluminum wheels; remote vehicle starting system; and Bluetooth connectivity for phones. SLT models also come with a chrome front bumper with a body-color top cap.

Sierra All-Terrain returns for 2011. This unique model is based on the popular Z71 Off Road package and offers a distinctive, eye-catching combination of style and refinement. It is outfitted with special shocks, unique four-bar grille, exclusive leather-appointed interior, 18-inch chrome wheels and more (see Sierra All-Terrain section below).

The Sierra Denali also returns. It's a truck that fuses performance and unmatched luxury, with features that elevate its performance and design - including a 6.2L all-aluminum V-8 engine with E85 FlexFuel capability, variable valve timing and a six-speed automatic transmission.

A family of 17-, 18- and 20-inch factory-installed wheels and tires is available throughout the Sierra range. Bright-finish 22-inch wheels are available as a dealer-installed option.

Spacious, refined interior

Sierra models are spacious with generous storage space. Sierra Work Truck and SLE come with a "pure pickup" interior that features larger controls, and door handles that are easy to use with gloves. SLE models are equipped with a standard 40/20/40-split front bench seat that features a fold-down armrest and storage compartment.

A large-capacity "double" glove box is integrated into the instrument panel on Work Truck and SLE models. Cloth seats are standard on SLE models and available on Work Trucks; leather seating is available on SLE models. Work Truck models are offered in a Dark Titanium interior color; SLE models are offered in an all-Ebony interior color, or Dark Titanium/Light Titanium and Ebony/Light Cashmere combinations.

SLT models feature a luxury-inspired interior with unique instrument panel, door panels, larger-capacity center console and other distinct trim.

A stadium-style rear seat with a 60/40-split design is standard on crew cab models and available on extended cab models. It can be easily folded up to provide an uninterrupted load floor. Alternatively, either section of the split seat can be stowed independently, allowing room for both cargo and a rear-seat passenger. Entry to the rear seat/storage area of extended cab models is easy with rear access doors that open 170 degrees.

A variety of useful convenience items are available on SLE and SLT models, including a touch-screen navigation radio, power-operated sunroof, power-sliding rear window and XM Satellite Radio.

Responsive driving experience

Sierra models' stability and driving confidence come from a boxed frame, coil-over-shock front suspension and rack-and-pinion steering. Five suspension systems are available, each tailored to suit specific driving requirements. They include:

- Z83 - Delivers a solid, smooth ride with 35mm-piston, twin-tube shocks and a 32mm front stabilizer bar

GM's sophisticated StabiliTrak electronic stability control system helps mitigate the occurrence of rollover events; it is standard on all models except with the 4.3L V-6 - and is a segment exclusive. Partnered with an improved, high-capacity brake system and four-channel, four-sensor electronic brake controls, the system provides more precise, controlled ABS stops, as well as enhanced traction/yaw stability.

An integrated trailer brake controller is available on regular cab, extended cab and crew cab models. It is integrated with the ABS system, and provides immediate and measured brake force signaling to the electric-controlled trailer brake system. There is no requirement for external and/or aftermarket brake control systems. The brake controller switch is conveniently mounted on the lower-left section of the instrument panel.
