GMC Sierra All Terrain HD Concept 2011

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.

2010 GMC Sierra 1500

2010 GMC Sierra 1500 is alongside the nearly identical Chevrolet Silverado. The Sierra’s wide, tall grille is its hallmark, with big GMC lettering inside; the boxy flares around its fenders are subtle reminders that this is the same brand that sells the extreme-looking 2010 Terrain crossover.

Inside the Sierra’s cabin, some models have a simple, upright design with larger controls and door handles-better suited for work duty-while pricey versions have an interior that would fit in a luxury sedan. The upgraded instrument panel has a smoother, lower design, as well as surfaces and materials that come together nicely.

The 2010 GMC Sierra Hybrid is more of the same; unless it’s fitted with the optional hybrid decal package and the hybrid LCD readouts, observers will likely not notice it as different from a standard Sierra pickup. The 2010 model year brings only minor changes to the Sierra, including revised interior door panels.

2010 GMC Sierra 1500 offer some powertrains option, There’s also a flex-fuel 5.3-liter V-8 with 315 hp and cylinder deactivation for improved fuel economy, which is standard in XFE models and available in other versions. The most expensive Sierra pickups get a 6.2-liter, 403-hp, flex-fuel V-8 that also shows up in the swank Cadillac Escalade. The 5.3-liter as it has plenty of power for most needs without much lower fuel economy than the base V-6. The base V-6 and base V-8 are teamed with a four-speed automatic; all other versions have a six-speed automatic that shifts very smoothly, helps achieve better fuel economy, and cuts down on noise. The Sierra gets up to 15/22 mpg in the XFE edition, falling to only 12/19 mpg in loaded versions.

2010 GMC Sierra Hybrid Crew Cab

GMC Sierra Hybrid Crew Cab is a powerful full-size pickup that achieves 40-percent greater city fuel economy and a 25-percent improvement in overall fuel economy while delivering the capability expected of a full-size truck – including a 6,100-pound (2,767 kg) towing capacity.

Thanks to the two-mode hybrid system and a powerful 6.0L gas V-8, the Sierra Hybrid delivers highly efficient performance, including all-electric driving up to 30 mph (48 km/h). Sierra Hybrid will deliver fuel economy that is expected to be the best in the full-size pickup segment, exceeding the current mileage leader – the non-hybrid Sierra.

It will be offered in the Crew Cab body style on both 2WD and 4WD models. Each model is equipped with several standard, popular features, including StabiliTrak electronic stability control system, a locking rear axle and a trailering package. Sierra Hybrid also offers dual-stage frontal air bags and head curtain side air bags.

The Sierra Hybrid’s fuel-saving performance is derived from GM’s advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM’s hybrid technology system not only enables the Sierra to launch and drive up to 30 mph on electricity alone, it also allows the Vortec 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.

Contributors to the quiet driving experience include:

• New exhaust system and resonator tuned for the 6.0L engine’s Active Fuel Management operation
• Additional engine intake induction tuning for reduced interior noise and pleasing sound quality
• Low-rolling resistance, “quiet-tuned” P265/65R18 tires for reduced road noise
• Electrically driven 300-volt air conditioning compressor reduces vibration and allows the standard, tri-zone HVAC system to cool the passenger compartment even when the gasoline engine is shut off
• Electrically driven 42-volt variable-assist power steering reduces vibration and provides up to a 0.5-mpg fuel economy improvement by reducing parasitic losses common in belt-driven hydraulic systems
• Energy Storage System (ESS) cooling system internal fan is tuned to be quiet at low vehicle speeds when the fan could more easily be heard by the occupants.

In addition, GMC Sierra Hybrid Crew Cab support by EVT, which is always provides abundant torque at all rpm levels for easy towing. t is particularly helpful on grades, as the EVT’s greater ratio spread allows the engine to hold optimal rpm for smooth, steady performance, with no hunting between higher and lower gears. The EVT incorporates grade braking and tap up/tap.

GMC Denali XT Concept, 2008

GMC Denali XT Concept, 2008

50-percent increase in combined fuel economy over comparable small pickup trucks when running on gasoline, and it incorporates a new, muscular form in a performance-styled, hybrid sport-utility truck (SUT).

The Denali XT has a unibody architecture and rear-wheel drive, enabling its distinctive design and efficient performance. It builds on the equity of the Denali line and its reputation for advanced engineering and refinement, the first combination of GM's two-mode hybrid system with an E85 ethanol-capable engine. Denali XT's new, more efficient 4.9L version of GM's small-block V-8 features fuel-saving technologies such as direct-injection technology and Active Fuel Management.

The engine is matched with GM's unique two-mode hybrid propulsion system, giving the powerful SUT exceptional fuel economy and uncompromising capability - including all-electric drive at low speeds. It is a powertrain combination that makes the Denali XT perfectly suited to a variety of active lifestyle activities, such as hauling skis and snowboards to the mountain or towing a sport jet boat to the lake.

With its unibody structure, the Denali XT is lighter than conventional body-on-frame trucks, with great ride-and-handling characteristics. This design enhances fuel economy while giving the vehicle a sporty driving experience. True to its GMC Professional Grade heritage, the Denali XT is filled with technologies and features that maximize its flexibility, including a cargo space-enhancing Midgate and height-adjustable suspension.
The Denali XT's proportions are framed around a high cowl and 123.4-inch (3,134 mm) wheelbase. This enhances the vehicle's truck functionality, but packages it in an efficient, unibody architecture.

Design and construction were spearheaded by Holden Design, within the Australian arm of GM's global design and engineering network.

The Inside,
The Denali XT blends mechanical functionality with leather-trimmed comfort.
Billet-metal surrounds, controls and instruments convey the cold precision of an aircraft cockpit. This is balanced by the warmth of bespoke saddle-leather trimmed seats and other contact surfaces.

The Denali XT seats four. The high-cowl vehicle architecture enables higher seating positions, allowing the couple distance between front and rear occupants to be reduced without compromising knee room. This packaging efficiency creates generous interior and cargo bed dimensions within a more compact package.

Truck capability
With stiffness that is greater than most conventional, body-on-frame trucks, the Denali XT's unibody structure supports a very capable truck platform. It also serves as the mounting point for a four-wheel independent suspension that gives the vehicle its performance feel on the road. The multilink front suspension features a forward-mounted steering rack and dual lower links with ball joints at the outer ends, providing sharp responses to driver input. At the rear, a four-link suspension design uses coil-over shocks and a decoupled stabilizer bar to enhance cornering control, reduce body roll and optimize longitudinal compliance. In short, it's a truck that hauls more than cargo on twisting roads.

The rear cargo area is wide, deep and flat, with no suspension or wheelhouse protrusions; the cargo floor measures 55 inches long (1,397 mm) by 47.5 inches wide (1,206 mm). It all adds up to the space to haul a wide variety of lifestyle accessories.

The easy-to-operate Midgate can be lowered to extend the cargo-carrying capacity inside the vehicle. The rear seats fold flat to provide a longer floor for carrying items such as skis, surfboards or wood from the home improvement store. A fixed rear window allowed engineers to retain the vehicle's structure, reducing mass and complexity.

The Denali XT has an estimated payload capacity of 1,100 pounds (499 kg) and a towing capacity of an estimated 3,500 pounds (1,587 kg). This capability is delivered through unique vehicle and powertrain integration, where the multiple modes of GM's two-mode hybrid system provide towing capability.

New 4.9L SIDI V-8 and two-mode hybrid system
The GM's rear-wheel-drive two-mode hybrid transmission is paired with a smaller-displacement version of the small-block engine. The new V-8 4.9L E85-capable engine powers the Denali XT with an estimated 326 horsepower (243 kW).
It uses direct-injection technology to produce the power of a larger engine, but consumes less fuel and produces lower emissions.

The Denali XT's two-mode hybrid system is partnered with the 4.9L engine and uses an electrically variable transmission to enhance fuel efficiency in city and highway driving. In city driving, all-electric propulsion is used at low speeds; on the highway, fixed-gear operation enables efficient performance even when towing a trailer.

Detroit 2010: Granite is the smallest GMC ever!

Mention GMC and the mental image for most will be full-sized trucks and SUVs with a mega grille to fit those three alphabets, but as we all now know, even the Americans are now turning to smaller vehicles that are more friendly to the wallet and environment. Which brings us to this, the GMC Granite concept, the smallest car ever to wear the famous logotype.

The Granite is 0.6 m shorter than the Terrain crossover, GMC’s current “baby”, but its interior is spacious and flexibleto fit the needs of “active people”. Generous cargo space and flipping/folding seats, for example, enable a mountain bike to be loaded completely inside with the tailgate closed. A decent 2,631 mm wheelbase means the claims are realistic.

“Granite was conceived as a new type of vehicle from GMC – one that could stretch people’s ideas of what a GMC can be,” said Lisa Hutchinson, product marketing director for GMC. “We call it an ‘urban utility vehicle’ and our goal was redefining what the GMC name could mean to a new generation of customers looking for both bold design and functionality.”

It seems to be a must-have these days, so the Granite gets rear-hinged “suicide” doors. GMC describes the Granite as an urban loft apartment on wheels with “urban-industrial design”. It reminds us a liitle of the Kia Soul, although this concept looks more butch, with a lower roof and wider stance. The glasshouse is very slim, but the flanks don’t look slab sided thanks to those deep creases that “cut through” the car. The wheels are pushed out to the extreme ends of the box and wheel arches are prominent. Looks quite cool to us!

Power comes from a 1.4-litre turbocharged engine matched with a six-speed dual-clutch transmission. This engine should be the ECOTEC turbo from the Chevy Cruze which makes 138bhp and 200Nm of torque.
