GMC Sierra continues to lead the industry in fuel economy, capability and power, all delivered with responsive ride and handling traits, and an exceptionally quiet driving experience. The lineup includes everything from job-ready Work Truck models to the unique combination of performance and luxury that is the Sierra Denali.

2009 GMC Sierra SLT Crew Cab2009 GMC Sierra SLT Crew Cab

For 2009, the Sierra lineup enhances its segment-best fuel economy with a new six-speed automatic that is paired with V-8 engines (except the 4.8L). Additionally, the 6.2L engine previously exclusive to the Sierra Denali is offered on SLT crew cab models; it is also more powerful than last year’s model and E85-capable. Other new features and content changes give customer more choices that support both safety and convenience.

“The ’09 Sierra lineup defines the essence of GMC,” said Susan Docherty, Buick-Pontiac-GMC vice president. “Its wide range of models offers the right truck for every need, but each does its job with characteristic refinement and dependability.”

A Sierra Hybrid model also is available beginning in 2009 and it delivers a 25-percent improvement in overall fuel economy while offering Sierra’s traditional capabilities – including a 6,100-pound (2,767 kg) towing capacity. Please see the separate Sierra Hybrid release for complete details and specifications.

New six-speed automatic transmission

A new Hydra-Matic 6L80 six-speed automatic transmission rolls out into the Sierra lineup. It helps the Sierra achieve better fuel efficiency on the highway through lower “cruising” rpm – less fuel is used with the lower engine speed. The reduced engine speed also enhances the interior’s quietness.

The 6L80 transmission debuts at the start of the model year’s production as standard equipment on Sierra crew cab models equipped with the 5.3L, 6.0L and 6.2L engines; the 6.2L-powered Sierra Denali crew cab was already equipped with the transmission. Later in the ’09 model year, the six-speed transmission will migrate to regular cab and extended cab models with the 5.3L and 6.0L engines.

2009 new features and changes

In addition to the new six-speed automatic transmission, a host of new features and revisions across the Sierra lineup gives customers more choices. The new features include:

The unique Sierra Denali, a truck that fuses performance and unmatched luxury, also returns for 2009.

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).

Sierra fuel economy

Sierra will continue to offer the broadest engine lineup and the best fuel economy in the full-size truck segment, including the best V-8 fuel economy with the 5.3L V-8. No other competitor in the class offers 300 horsepower and EPA-rated 20 mpg in estimated highway fuel economy.

Sierra design

The 2009 GMC Sierra is designed with a strong and refined appearance befitting the brand’s professional grade philosophy, including muscular character lines and rounded edges. The front-end appearance, front fenders, hood and rear fenders are unique. A “center-focused” hood, which flows outward to meet the front fenders and stamped-in rear wheel flares, enhances the muscular look.

All models except the work truck model come with a distinctive chrome hood molding. Sierra’s grille is complemented by large, jeweled-appearance headlamps. Sierra SLT models come with a chrome front bumper with a body-color top cap. All door handles feature large, grab-style designs that are easy to open with gloves.

A family of 17-, 18- and 20-inch factory-installed wheels and tires is available throughout the Sierra range, with Sierra Denali offering unique wheels (see Sierra Denali section below). Also available are bright-finish 22-inch wheels that are available as a dealer-installed option.

Spacious, refined interior

Sierra models are more spacious with increased storage space, as well as flush surfaces, tight gaps and tolerances, and improved comfort and convenience. 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. Heated, 10-way power-adjustable driver’s seat, leather seating surfaces, Bose speaker system and heated windshield washer system are standard. Crew cab SLT models add a rear-seat audio system. SLT interior color schemes include all-Ebony, Dark Titanium/Light Titanium and Dark Cashmere/Light Cashmere combinations.

Standard on crew cab models and available on extended cab models is a stadium-style rear seat with a 60/40-split design. It can be easily folded up to provide an uninterrupted load floor. Or, 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 eased 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. A rear-seat entertainment system is available on crew cab SLE and SLT models, and all models are available with a variety of radio systems. XM Satellite Radio is standard on all models.

Responsive driving experience

The 2009 GMC Sierra delivers stability and driving confidence 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
* Z85 – Designed for enhanced handling and trailer towing, with 46mm-piston, monotube shocks and a 34mm front stabilizer bar
* Z71 – Delivers enhanced off-road capability; features 46mm shocks, off-road jounce bumpers and a 34mm front stabilizer bar; the package also includes a skid plate, heavy-duty air cleaner and Z71 decals on the rear fenders
* Z60 – Designed for maximum street performance and offered with 20-inch chrome-clad aluminum wheels
* NHT – Designed for maximum towing capacity

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.

Integrated brake controller

The 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.

Sierra powertrains

Sierra models are powered by an efficient lineup of engines, led by the segment’s highest-rated V-8 engines. Advanced technologies such as Active Fuel Management (AFM) and variable valve timing (VVT) help Sierra deliver the segment’s best fuel economy. FlexFuel engines are available – and partnered with fuel-saving AFM – giving customers the choice of powering their truck with E85 ethanol, gasoline or a combination of both fuels. Light-duty engine offerings include:

* 4.3L V-6 (LU3), rated at 195 hp (145 kW) and 260 lb.-ft. of torque (353 Nm)

The engines are backed by proven Hydra-Matic electronically controlled automatic transmissions, including the 4L60 four-speed automatic and the fuel-saving 6L80 six-speed. Previously exclusive to the Sierra Denali with the 6.2L engine, the 6L80 transmission rolls out throughout 2009 to all models equipped with the 5.3L and 6.0L engines.

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.

Safety and security

As evidenced by its five-star frontal crash test rating from NHTSA, Sierra delivers a perimeter of safety protection through a stronger frame and body structure as well as industry- and segment-leading technology. It also is designed to provide increased compatibility with other vehicles. Features include segment-first StabiliTrak electronic stability control with rollover mitigation technology, head curtain side air bags, which are integrated into strengthened chassis and body structures to provide excellent passenger protection, and segment-first safety belt pretensioners that activate during a rear-end crash. The head curtain side air bags are available on Sierra SLE and SLT models; they are standard on Sierra Denali models.

Driver control dynamics are enhanced by wider front and rear tracks, as well as more responsive suspensions – including a coil-over-shock front suspension design and rack-and-pinion steering. Additional safety features are offered on Sierra, including factory-installed remote vehicle starting (segment exclusive); Autotrac active transfer case to help keep the vehicle sure-footed in slippery driving situations; Ultrasonic rear parking assist and a tire pressure monitoring system.

All retail models come standard with the OnStar Generation 8.0 system, including a one-year subscription to the Safe & Sound plan. The OnStar service includes the Advanced Crash Response System, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen and provides remote door-unlocking service (when the vehicle is equipped with power door locks).

It is powered by a 6.2L V-8 engine, rated at 403 horsepower (301 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 helps deliver an excellent balance of performance and fuel economy.
