GMC Sierra All Terrain HD Concept 2011

ADVERTISEMENTS

The new Sierra HD underpins the All Terrain HD concept, with a modified, production-based 4WD chassis and the Duramax diesel/Allison 1000 six-speed powertrain. The enhanced suspension and unique body dimensions, including increased ground clearance and wider track, as well as greater approach/departure angles, deliver off-road capability while maintaining HD levels of payload and trailering capacity. The All Terrain HD is painted Iridium Metallic – a dark charcoal color that reveals a reddish, anodized inflection when viewed from certain angles.

Based on the chassis of the 2011 Sierra HD trucks, the All Terrain HD features a fully boxed steel frame with exceptional strength and torsional stiffness. It incorporates the production models’ new independent front suspension and asymmetrical rear leaf-spring suspensions, but with a wider 73-inch (1,853 mm) track (front and rear) that enhances stability during off-road and highway driving. A production Sierra 2500HD has front and rear tracks of 68.8 inches (1,748 mm) and 67.3 inches (1,709 mm), respectively.

The GMC Sierra All Terrain HD concept is propelled by the new, production 6.6L Duramax turbo-diesel V-8 and Allison 1000 six-speed automatic transmission powertrain combination offered in the 2011 Sierra HD trucks. The Duramax is rated at 397 horsepower (296 kW) and 765 lb.-ft. of torque (1,037 Nm).

The powerful 6.6L Duramax is more fuel-efficient – with up to 11-percent greater fuel economy than previous versions – and reduces NOx emissions by up to 63 percent. The powertrain’s efficiency is assisted by the Allison 1000 transmission, which requires less engine power to funnel torque to the axles. It also incorporates a “smart” exhaust brake feature that helps save wear on the brakes on downhill grades, a feature available on production Sierra HDs.

GMC today announces the new 2011 Sierra Denali HD, the first offering of the exclusive Denali line on a heavy-duty GMC pickup. The Sierra Denali HD leads a comprehensively redesigned lineup of 2011 Sierra 2500HD and 3500HD trucks that go on sale in early summer – including the most powerful diesel engine in the segment.

Sierra HD’s new 6.6L Duramax turbo diesel delivers 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm.

The Sierra Denali HD comes exclusively on the 2500HD chassis, in a 4WD crew cab standard box configuration. A Vortec 6.0L gas V-8/six-speed automatic powertrain is standard and the new Duramax 6.6L turbo diesel/Allison 1000 six-speed transmission powertrain is available.

The iconic Denali four-bar, chrome grille with round air inlets distinguishes the Sierra Denali HD on the outside, along with body-color bumpers, chrome door handles, chrome accents and 18- and 20-inch polished forged aluminum wheels.

The balance of the new 2011 Sierra HD lineup is identified on the outside by new, three-bar grilles and powertrain-badged louvered hoods, along with a revised, full-width chrome steel front bumper and a new family of 17-, 18- and 20-inch wheels. It’s beneath the skin, however, where they are truly separated from their predecessors – and the competition.

All-new 2010 GMC Terrain makes its world debut at the 2009 New York International Auto Show. The GMC Terrain is a five-passenger crossover SUV that blends bold styling with fuel efficiency and premium features."The new Terrain brings GMC's history of innovation and engineering excellence into a smaller, fuel-efficient package for today's buyer," said Susan Docherty, Buick-Pontiac-GMC vice president. "The capability attributes that make a vehicle a GMC are ingrained in GMC Terrain, making it an appealing choice for existing traditional SUV customers who are looking for distinctive styling and increased efficiency."

A new, 2.4L four-cylinder engine that features direct injection is expected to deliver best-in-segment highway fuel economy of 30 mpg. Maximum fuel economy is achieved in part with an "ECO" mode that is activated via a console-mounted button. When engaged, it lowers the torque converter lockup speed to 1,125 rpm to help save fuel on models equipped with the 2.4L engine.
Also available will be a 3.0L DOHC direct injected V-6 engine delivering an estimated 264 horsepower (197 kW). Both engines are mated to efficiency-enhancing six-speed automatic transmissions and offer a refined, confident driving experience.
"GMC is a strong, core brand for GM and the GMC Terrain crossover SUV is the latest example of how we're adapting to changing market conditions," said Docherty. "As we first demonstrated with the Acadia crossover, GMC is committed to offering the capable vehicles customers seek, with the personal technologies they expect."

The 2010 Terrain goes on sale in late summer, with front-wheel-drive and all-wheel-drive models offered in SLE and SLT trim levels. A comprehensive list of standard and available features includes purposeful technologies such as:

- Standard rear vision camera
- Programmable power rear liftgate
- Bluetooth hands-free phone capability
- MultiFlex sliding rear seat that increases passenger comfort or provides optimal cargo space
- Remote vehicle start
- USB audio connectivity; MP3 playback
- Seven-inch touch-screen navigation system and a 40-gigabyte hard drive
- DVD-based rear-seat entertainment system with two independent screens
- Standard OnStar and XM Satellite Radio
Segment-best safety is anticipated, with features that include four-wheel disc brakes with StabiliTrak electronic stability control and traction control, as well as six standard air bags: dual frontal air bags; head curtain side air bags and pelvic/thorax seat-mounted side air bags. OnStar with one-year Safe and Sound service is also standard.
Bold styling
GMC Terrain has a balanced, athletic stance and offers a commanding view of the road. Its design is characterized by bold, muscular fender flares, representing GMC's aesthetic. Surfacing is angular yet refined, with a strong and capable front-end appearance that features precise, squared-off edges.
"We wanted to carve the GMC Terrain away from the pack and establish its identity as a powerful, fresh crossover SUV with a confident and strong stance," said John Cafaro Jr., director of exterior design, Global Crossover Vehicles. "Everything about the GMC Terrain communicates a sense of tailored toughness and passionate craftsmanship."
Additional design features include a unique, three-element grille that is accented by a prominent chrome surround and projector-beam headlamps mounted in large, rectangular housings with chrome accents.
Interior details and flexibility
The GMC Terrain's rich, premium interior is influenced by industrial sculpture and exudes refinement exemplified by contrast stitching and fine materials that create a structured look throughout the cabin. A "floating" center stack, highlighted by warm ambient lighting, houses a multitude of ergonomic comfort and convenience controls.
The GMC Terrain also features great attention to detail, with smart use of storage space and compartments that are suitable for a variety of items. They include an oversized glove box; a closed storage area in the instrument panel above the center stack; a closed storage compartment under the center armrest large enough for a laptop computer; and two-tier storage in the doors.
GMC Terrain's seats were developed to provide outstanding comfort and the standard MultiFlex sliding rear seat can be moved fore or aft nearly eight inches (200 mm), providing increased passenger comfort or greater rear cargo capacity. The 60/40-split rear seatback offers additional configurations for passengers and cargo; and the rear cargo area offers 31.6 cubic feet (894 liters) of storage, as well as one of the GMC Terrain's four auxiliary power outlets.
Confident and agile driving experience
Two new engines are offered on all GMC Terrain models, each with fuel-saving direct injection and variable valve timing technology. Vehicle highlights include:

• - New 3.0L DOHC direct injected V-6 engine estimated at 264 horsepower (197 kW), which delivers an estimated 25 mpg highway, 18 mpg city (EPA certification pending).
• - New 2.4L Ecotec direct injected I-4 engine estimated at 182 horsepower (136 kW) that delivers an estimated 30 mpg highway, 21 mpg city (EPA certification pending)
• - Driving range of more than 500 miles (800 km) with both engines, for less-frequent fill-ups

The powertrains are mounted on a rigid, body-integral structure, with single-piece body side stampings and targeted applications of high-strength steel. It is the foundation of a confident driving experience that is both smooth and responsive.
GM's first application of Active Noise Cancellation (ANC) technology is used on 2.4L-equipped models. ANC uses microphones to detect booming sounds inside the vehicle and sends counteracting sound waves through the audio system's speakers, ensuring a quiet driving experience at almost all vehicle speeds.
The GMC Terrain rides on a 112.5-inch (2,857 mm) wheelbase and features a four-wheel independent suspension system, with wide front and rear tracks that enhance the ride and handling. A family of 17-inch, 18-inch aluminum and 19-inch chrome-clad wheels is available.
GMC Terrain's rack-mounted electric power steering system provides greater fuel efficiency on four-cylinder-equipped models, saving nearly 11 miles per tank of gas.
GMC Terrain will be produced at the CAMI assembly facility in Ingersoll, Ontario.
