The 2009 GMC Sierra: In A League Of Its Own

GM Media Release
17 December 2008

Leading the segment in performance, efficiency, capability, and safety, the 2009 GMC Sierra really is in a league of its own. Since its launch two years ago, the full-size pick-up as established a distinct identity to highlight its capability, quality and performance.

The Sierra is offered in three cab styles, three cargo box lengths and several specially tuned suspensions. All have brand-exclusive sheet metal and design cues and share fundamental traits that are well ahead of its competitors. There is also the top-of-the-line Denali offering, which brings levels of specification more akin to a luxury sedan to the Sierra range.

“With our deep-seated knowledge of how to produce quality pick-ups, the quality shows in the Sierra, with its segment-leading V8 power, fuel efficiency and towing capacity,” said Karim Corm, GMC Marketing Manager in the Middle East. “These days, power, pulling and payload define the price of entry, and consumers demand more. The Sierra features spacious and refined interiors and a host of exclusive attributes. In essence, it has everything it needs to become a mainstay in the industry.”

The 2009 edition takes GMC’s professional grade philosophy to heart, particularly with its strong and refined appearance, muscular character lines and rounded edges. The look of the Sierra’s front-end appearance, hood, bumpers, lamps and rear box design are unique to the GMC brand. The windscreen is swept back by 57 degrees to aid not only the aerodynamics but also to cut wind noise, and help enhance fuel efficiency. Jewelled lamps further add to the visual appeal.

Incorporating a host of class-leading features, the Sierra range comes with a choice of three cargo beds: short, standard and long. Innovative new features such as 170-degree-opening rear access with fully retractable power windows on extended cab models, and new theatre-style folding rear seats offer increased versatility.

The cargo boxes were recently redesigned to enhance versatility, and give greater capacity while being much stronger than ever before. These feature newly developed, reduced-effort tailgates; a standard end cap on each tailgate makes for an integrated spoiler lip in a move to enhance aerodynamics. Meanwhile, an innovative cargo management system is available on all Sierra models, which is complemented by a range of dealer-ordered accessory packages.

GMC is well known for the quality of its vehicles, and build precision is no different on the Sierra. All panels are flush – hood-to-fender gap is targeted at 4 mm – with a virtually seamless transition between the hood and front fenders, while there are extremely tight tolerances around the grille, fenders and front bumper. The grille-to-bumper gap has been reduced to 17 mm and the headlamp-to-fender gap to just 1.5 mm. The tighter tolerances contribute to the truck’s excellent aerodynamics.

The 2009 Sierra is extremely quiet, spacious and refined in the interior, and is designed around the comfort and convenience of passengers, providing a wealth of storage space. The model features distinct interior designs that reflect the brand identity, including specific trim, appointments and gauge cluster appearance.

The interiors of the base and mid-level trim models are designed around a functional “pure pickup” theme. This takes a contemporary adaptation of an ergonomic cockpit instrument panel design, and in addition, the interior includes door panels with large door pull and release handles, seat construction and configurations, unique centre console and under-seat storage systems, and two glove boxes – a traditional lower glove box and a covered upper storage compartment – that provide 3.4 litres of storage capacity.

Models equipped with the luxury-inspired premium interior come with a single large glove box that offers approximately 25 per cent more storage capacity. This interior includes large centre consoles with the segment’s highest storage capacity: 20.1 litres of undivided volume. The “pure pickup” interiors feature a 6.1-litre storage console and an under-seat storage bin built into a new 40/20/40-split bench seat. This 9.1-litre lockable storage bin, which includes an accessory power outlet, is located under a centre seat cushion and is large enough to store a laptop computer.

The “low and forward” instrument panels in each model help provide a real feel of spaciousness, and give an airy impression inside, as well as a panoramic field of vision. Both instrument panel designs are integrated into their specific door panels to create a sweeping appearance.

The way the interior is laid out forms plenty of legroom, headroom and hip room. The front seats gain from a wide recline angle and long fore/aft travel, while power adjustable pedals are available, leading to greater flexibility in driver comfort. The stadium-style rear seat, with a 60/40-split design and centre folding armrest, easily folds up to give an uninterrupted load floor.

All interiors are designed to appear refined, while the high level of craftsmanship is highlighted by flush surfaces, tight gaps and tolerances on the instrument panel, centre stack, clusters and other components. Most gaps on the instrument panels and clusters are incredibly narrow, measuring 0.5 mm or less. Soft-touch and low-gloss finishes for the instrument panels and other trim pieces are used throughout; the colour and grain of the materials are carefully selected to provide a premium look.

Meanwhile, segment-leading quietness complements finely crafted look and feel of the interiors; all trim levels – even base work truck models – provide a passenger environment that is almost devoid of noise. This remarkable quietness is achieved through the use of strategically placed sound deadening and sound absorbing material in the body structure – including a liquid-applied dampener on the floor and front-of-dash – as well as through the inherent vibration-minimising traits of the stiff frame and the sleekness of the aerodynamically tuned exterior.

The 5.3-litre comes with a powerful engine generating 320 hp @ 5300 rpm and 459 Nm @ 4200 rpm for the 2009 model. Also newly arrived is the Hydra-Matic electronically controlled, six-speed automatic transmission, with Driver Shift Control. This system helps the Sierra achieve better fuel efficiency on the highway through lower cruising rpm, which means less fuel is used with the lower engine speed. The reduced engine speed also enhances the interior’s quietness.

The fourth generation of the legendary small-block V8 engine family delivers segment-leading horsepower and fuel efficiency through advanced technology such as Active Fuel Management (AFM). This proprietary GM fuel-saving system bolsters the truck’s capability with the segment’s best fuel efficiency. Highway consumption for models equipped with the 5.3-litre AFM V8 now are estimated at under 12 l/100km for both 2WD and 4WD models.

A comprehensively designed chassis and suspension system channels the entire engine’s power into the Sierra’s established capability and refined, responsive drive. These features are designed to give a smooth and precise feeling of control at all times, and particularly when driving on rough surfaces or with a full load.

The chassis and suspension also support the Sierra’s class-leading capability, including segment-best towing capacity of 4,763 kg and a maximum payload of 980 kg. There are two suspension systems available: Z85 for superior handling and trailer towing and Z71 for enhanced off-road capability.

The Sierra’s fully boxed frame is significantly strong and stiff, with a hydroformed front section, enhancing both smooth ride and crash protection. The coil-over-shock front suspension is mounted to the frame via a high-strength, precise attachment system, while the rack-and-pinion steering delivers precise, responsive control with enhanced on-centre feel. At the rear, a Hotchkiss-type rear suspension with splayed shock absorbers – angled outward and upright – provides controlled damping and is a key contributor in the pick-up’s firmly-planted driving feel.

A large-capacity brake system and standard next-generation Bosch ABS system provide shorter stopping distances, excellent pedal feel and quicker brake response. StabiliTrak electronic stability control comes as standard on crew cab models, and is available as an option on extended cab variants. This is a first for the segment, and it incorporates rollover mitigation technology that works with the ABS brake system to provide greater driver control in all driving conditions.

The Sierra boasts a host of active and passive safety features. It is built on strong fully boxed frames that are designed to provide increased crush protection during a crash, while high-strength steel reinforcements are strategically located on the frame to enhance crashworthiness.

The wide-track, rack and pinion steering and coil-over-shock front suspension structure ensures supple handling in all conditions, while front dual stage air bags, side curtain bags along with seat belt pretensioners are all available to keep occupants safe. Add to this a four-channel ABS system – which is standard on all models – allied to the StabiliTrak electronic stability control system that helps mitigate the occurrence of rollover events.

Four-wheel drive models feature the Autotrac active transfer case, which helps keep the vehicle surefooted in slippery driving conditions. When shifted to the “Auto” mode, Autotrac engages all-wheel drive traction automatically. The Sierra comes with a range of 17-inch wheels for a tailored body-to-wheel relationship.

The Ultrasonic Rear Parking Assist system is available and provides visual (LED lights) and audible warnings of objects behind the vehicle.

An easy-to-use tyre pressure monitoring system is standard on all models. This alerts the driver via a signal on the instrument panel’s driver information centre if a tyre’s inflation status requires attention.

A segment-exclusive factory-installed remote vehicle starting system is available on most models, providing customers with the ability to start the vehicle and cool it down during hot weather.
