GMC DENALI XT CONCEPT

GM Holden’s global design capability was showcased today on the world stage when GMC took the covers off a stunning concept vehicle at the 2008 Chicago Auto Show.

The GMC Denali XT was designed and constructed at GM Holden’s design centre in Port Melbourne, Victoria. GMC drew upon General Motors’ global resources and expertise in Australia to produce the show stopper.

Lead Designer, Warrack Leach - who also recently led the VE Ute design - created the Denali XT’s new, muscular form in a performance-styled, hybrid sport-utility truck (SUT).

“This was a great program to work on as I was given the opportunity to really stretch the limits of the Global Rear Wheel Drive architecture and create a truck with unique and bold proportions,” Leach said.

“GMC has such a rich heritage of producing great trucks and it was essential we kept that in mind while at the same time exploring how far we could take this concept.”

The Denali XT has a unibody architecture and rear-wheel drive which enables its distinctive design and efficient performance.

Denali XT’s new, more efficient 4.9L version of GM’s small-block V8 features fuel-saving technologies such as direct-injection technology, Active Fuel Management and includes the first combination of GM’s two-mode hybrid system with an E85 ethanol-capable engine.

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.

The Denali XT boasts an estimated 50-percent fuel economy improvement over comparable small pickup trucks when running on petrol.

Jim Bunnell, GMC General Manager, said although just a concept, the Denali XT was 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.

“Like all GMCs, the Denali XT is functional and capable, but it blends those traits with a more efficient, sporty driving experience,” said Bunnell.

“It is a vehicle that exemplifies GMC’s engineering excellence, as well as GM’s commitment to hybrid and advanced technologies.”

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 carefully design proportions are framed around a high cowl configuration that enhances the vehicle’s truck functionality, but packages it in an efficient, unibody architecture that enhances fuel economy while giving the vehicle a sporty driving experience.

Exterior

The Denali XT features a muscular form and wide, firmly planted stance giving the vehicle a confidently capable road presence. Minimal overhangs, huge 23 inch wheels, custom Kumho tyres, sleek headlamps and a low roof profile deliver an aggressive, performance-oriented appearance.

The Denali XT’s design includes a new take on GMC’s iconic grille, with a prominent, four-bar element in addition to the large, red GMC logo and signature Denali background.

The wide road stance is accentuated by flared fenders and enhanced further when the Denali XT is lowered on its air-adjustable suspension, creating a sleeker appearance that simultaneously improves aerodynamics.

Ed Welburn, Vice President GM Global Design, describes the concept as a robust yet tailored design statement that is unlike anything else on the road.

“It has the youthful look of a custom automobile that incorporates the capability customers expect from a truck,” Welburn said.

The exterior colour "Battle" is described by GM Holden’s colour and trim team as a cool mid tone liquid gunmetal which is balanced against the polished aluminium details.

Interior

Warrack Leach, Lead Designer, says 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,” Leach says.

“The form language is smooth and structured to characterize GMC’s power. The details have a deliberately contrasting mechanical aesthetic to mark GMC’s engineering sophistication.”

A feeling of luxury is created with soft grey microsuede finishes while keeping the integrity of a functional product with the hard saddle, workboot brown leather.

The interior features innovative instrumentation with “floating” red-illuminated numerals backed by surface chaplets in the clusters and a large integrated vehicle interface screen.

The Denali XT seats four comfortably as the high-cowl vehicle architecture enables higher seating positions, allowing the 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. 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 with dimensions that create the space to haul a wide variety of lifestyle accessories.

Functionality is enhanced with an easy-to-operate Midgate that can be lowered to extend the cargo-carrying capacity inside the vehicle.

The Denali XT has an estimated payload capacity of 499kg and a towing capacity of an estimated 1,587kg. This capability is delivered through unique vehicle and powertrain integration.

New 4.9L SIDI V-8 and two-mode hybrid system

For the first time, GM’s rear-wheel-drive two-mode hybrid transmission is paired with a smaller-displacement version of the small-block engine. The new V8 4.9L E85-capable engine powers the Denali XT with an estimated 243kW. It uses direct-injection technology to produce the power of a larger engine, but consumes less fuel and produces lower emissions.

The functionality of GM’s Active Fuel Management system has been expanded through the use of hybrid technologies, enhancing the cylinder-deactivating feature to further improve fuel efficiency.

The Denali XT’s two-mode hybrid system 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.

The GMC Denali XT concept will be on show at the Chicago Motor Show from 6 – 17 February 2008.

ALL-NEW 2010 GMC TERRAIN

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

- 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 .

GMC YUKON DENALI HYBRID

* New exterior colors: Taupe Grey Metallic and Sheer Silver Metallic replace Blue Granite Metallic, Silver Birch Metallic and Deep Ruby Metallic
* USB connectivity in center console, enabling stored audio files to play through the audio system and battery charging for some handheld devices

The GMC Yukon Hybrid broke ground with the world's first production 2-Mode full hybrid propulsion system, which on the 2WD model offers 21 mpg in city driving – a 50-percent improvement over non-hybrid models. The lineup now includes the distinctive Yukon Denali Hybrid, which infuses a new level of luxury into the efficient utility vehicle.

Along with exceptional fuel economy, the Yukon Hybrid and Yukon Denali Hybrid deliver full-size capability – up to 6,200 pounds (2,812 kg) of towing capacity (2WD) and standard eight-passenger seating capacity.

Yukon Hybrid models are built on GM's full-size SUV platform, which incorporates features such as a fully boxed frame, coil-over-shock front suspension, rack-and-pinion steering and a premium interior that bolsters the vehicle's comfort, quality and capability. Wide front and rear tracks enhance handling and lower the center of gravity for a more confident road feel.

The Yukon Hybrid was designed with safety in mind. It delivers a 360-degree safety system of occupant protection and crash-avoidance technology, with features such as standard StabiliTrak stability control system with rollover mitigation technology. For 2010, the long list of standard safety features is enhanced with the addition of front seat-mounted side air bags on all models.

Yukon Denali Hybrid details

The Yukon Denali Hybrid rides on unique 22-inch, eight-spoke, flangeless chrome wheels that make a stylish Denali appearance statement.

Inside, designers filled the cabin with luxurious amenities such as standard 12-way power, heated/cooled leather-appointed perforated front seating and heated, second-row, leather-appointed bench seating. Buyers may choose an Ebony or Cashmere interior. The only three options on this fully equipped vehicle are a sunroof, rear-seat entertainment DVD system and side blind zone alert mirrors.

Enhanced connectivity includes standard OnStar with Directions & Connections and Turn-by-Turn Navigation, navigation radio with rear camera system, a Bose Centerpoint Surround Sound System and three years of real-time XM NavTraffic.

A comprehensive safety package of crashworthiness and crash-avoidance features includes front- and side-impact air bags, anti-lock brakes and StabiliTrak with traction control. The Yukon Denali Hybrid also is equipped with GM's MagnaRide suspension, the first application of this advanced technology in a Yukon . MagnaRide uses magnetic particles in the shock absorber fluid to adjust the damping rate of the shock absorbers – based on road conditions and vehicle dynamics – to help keep tires in contact with the road.

Patented, industry-leading hybrid technology

The Yukon 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 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 Yukon to launch and drive up to 27 mph (43 km/h) on electricity alone, it allows the Vortec 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.

As part of the vehicle's emission control system, the ESS is warranted for eight years/100,000 miles.

In the Yukon Hybrid and Yukon Denali Hybrid, the hybrid system itself generates the electricity to propel the vehicle. When the brakes are applied or the vehicle is coasting, the electric motors in the hybrid system create electricity and store it in the 300-volt battery. This electricity helps move the vehicle.

The hybrid system provides seamless, dependable power on demand in an efficient package. In fact, its electric motor is less than half the size of those in single-mode hybrid systems. This technology was developed and is still used in fleets of hybrid transit buses in more than 70 North American and European cities. Scaled down for use in passenger vehicles, the two-mode system delivers fuel savings where it is needed most – in large vehicles with high levels of capability. The two-mode system was first introduced on the 2008 Yukon Hybrid. It is a core part of GM's energy diversity efforts, centered on reducing dependence on petroleum, improving fuel economy, reducing emissions and minimizing the automobile's impact on the environment.

Quiet and smooth

Integration of the hybrid system on the Yukon is seamless – the battery pack is beneath the second-row seat – and delivers a quiet driving experience. Contributors to this include:

* Specific 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.

Along with quietness, the Yukon Hybrid also delivers exceptional driving smoothness, thanks to specifically tuned shocks.

Trailering performance

In addition to increased fuel economy, the Yukon Hybrid's electrically variable transmission also provides tremendous trailering capability, enhancing driving smoothness and quality when towing.

Electric drive is enabled up to 27 mph (43 km/h), saving fuel even when the truck is towing a trailer.

The EVT incorporates grade braking and tap up/tap down shift control. It also benefits towing on curves or lower-speed back roads, as exceptionally smooth gear transitions eliminate the "shift shock" torque disruption that can occur during abrupt shifts, such as when slowing or braking.

In addition to the eight-year/100,000-mile warranty on the Yukon Hybrid's Energy Storage System, GM's five-year/100,000-mile Powertrain Limited Warranty continues to make GM a better choice for customers. GM's coverage focuses on the complete ownership experience and includes other provisions that competitors do not offer, including transferability to the next owner, more complete coverage of parts, and coverage for new and certified used vehicles. In addition, GM offers complementary courtesy transportation and roadside assistance .

INDUSTRIAL-INSPIRED GMC GRANITE CONCEPT

DETROIT – Combining a decidedly urban-industrial design aesthetic with functionality aimed at young professionals, the GMC Granite concept takes the brand’s trademark capability in a new, more progressive direction. It was introduced at the 2010 North American International Auto Show in Detroit.

If brought to market, the Granite would be the smallest GMC ever – but has been optimized to feel much larger. Its length is a full 2 feet (0.6 m) shorter than the new Terrain compact crossover, but its open interior was designed to be spacious and flexible to fit the needs of active people. Generous cargo space and unique flipping/folding seats, for example, enable a mountain bike to be loaded completely inside with the tailgate closed.

“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.”

Like GMC’s current lineup of trucks, SUVs and crossovers, the Granite delivers style and capability, with advanced features, high-quality materials and exceptional attention to detail. An industrial-influenced exterior is combined with a spacious interior that features precise instruments and leading-edge technology. The climate system, navigation and infotainment technologies, for example, are viewed via an extra-wide, next-generation organic light-emitting diode technology that is more dynamic than the conventional screens used in most production vehicles.

“We think of the Granite as the automotive equivalent of an urban loft apartment,” said Dave Lyon, executive director of North American Interior and Global Cross-Brand Design. “The exterior has an unmistakable industrial look, but the interior is warm and personalized.”

Power for the Granite concept comes from a 1.4L turbocharged engine that is part of GM’s new family of small-displacement, highly efficient four-cylinder engines. It is matched with a six-speed transmission.

Industrial-inspired exterior

A cadre of young designers drew upon the preferences of young, urban professionals like themselves, who are very social and active. They are more likely to take friends to clubs and load outdoor gear on weekend excursions than to haul lumber or tow a boat. With those requirements in mind, they sketched out the dimensions of the Granite accordingly. Its 103.6-inch (2,631 mm) wheelbase is comparable to a Chevrolet Cobalt, but its 161.3-inch (4,097 mm) overall length is more than a foot shorter. Its size gives the Granite exceptional maneuverability, even within narrow urban streets.

The Granite’s comparatively short body length is complemented by a wide, 70.3-inch (1,786 mm) overall width and a tall, 60.5-inch (1,536 mm) height. Those dimensions create unique proportions that depart dramatically from conventional minivan, SUV or crossover designs. “The Design team leveraged the best attributes from different segments: SUV, minivan and crossover, and mixed them with a commercial chic aesthetic. We feel this redefines the premium class of vehicles we call urban utility vehicles,” said Lyon.

Granite has four doors, hinged on each side to open like a set of French doors. There’s no pillar between the front and rear doors, making the Granite easier to enter, exit and load, even with bulky items.

“We gave the Granite a bold yet appealing design that truly makes a styling statement,” said Juho Suh, exterior design manager. “For a new generation of urban professionals, it delivers the look and functionality they need.”

In keeping with the vehicle’s urban theme, the exterior of the Granite has a series of complex, intersecting planes and angles, creating the impression of an industrial machine – an object created out of necessity, but admired for its precision and functional aesthetics.

A forward-angling motif that cuts through the door panels, starting high and behind the doors and cutting to the center of the front door, suggests motion, as does a high beltline and tapered side glass. A rear spoiler is integrated into the roof and extends slightly above the rear glass. Other angles and planes of the exterior appear carefully metal-crafted.

Up front, GMC’s signature grille design is flanked by headlamps that sweep back into the fenders, further suggesting motion. The headlamps and fog lamps are set at the far edges of the front-end bodywork, accentuating the Granite’s planted stance. At the rear, the vehicle’s planes and angles come together tightly, showing careful attention to detail. Other exterior elements include prominent taillamps with a multi-layer appearance and LED lighting technology; and a centered exhaust outlet with a brushed metal tip.

There is no chrome on the exterior of the Granite; all the trim has a satin or brushed metal finish, accenting the industrial look. Large, 20-inch wheels – wrapped in Bridgestone tires – were tailored within the fenders for a low, sporty stance. The exterior color of the Granite is metallic gray that evokes the look of the material for which this concept was named.

Mechanically minded, highly functional interior

The interior was inspired by the design of aircraft-type mechanical instruments and precision tools. That is most apparent on the dashboard and instrument cluster, where gauges were modeled after finely crafted timepieces. A compass incorporated into the “barrel” surrounding the speedometer moves with every turn of the vehicle, providing an at-a-glance directional confirmation. “Our goal was not to hide but to show how this vehicle is put together, and the high quality of its craftsmanship, not unlike the finest industrial-inspired luxury time pieces,” said Lyon.

Red backlighting illuminates the gauges, while a panel of organic light-emitting diode screens is the foundation for the vehicle’s navigation, infotainment, phone and climate control readouts. The screens represent the next generation in vehicle information displays, with bright, multidimensional readouts and intuitive controls that give the Granite a modern feel.

Integrated within Granite are unmistakable GMC cues, including a center stack wing motif similar to that of the new GMC Terrain. A prominent center console runs between the front and rear seats, with ports to plug in popular portable electronic devices, as well as storage compartments large enough for a laptop computer.

The center console also houses a unique transmission shifter. Rather than a handle that actuates within a conventional gate, it is a simple, space-saving knob that rotates with the precise clicks of a torque wrench. The gear selections are confirmed via LED indicators.

Among the most functional elements of the Granite concept are reconfigurable seats. The front passenger and right rear seats flip up and fold in toward the center console, creating a long, unobstructed storage space. The Granite functionally addresses the needs of young professionals and their activities without compromises.

The cargo area includes a number of compartments to store items out of sight. Cargo hold-down provisions are built into the cargo area and the seatbacks have clasps that can be used when the seats are upright or folded to help secure cargo.

The Granite’s interior is finished with dark tones on the bottom and complementing, lighter colors on top, including suede-like Nubuck material on the seats and instrument panel. The interior is further accented by satin-finish and anodized trim. The instrument panel gives the impression of a command console, with driver-focused instruments and controls set in an anodized panel.

“The look, feel and functionality of the instrument panel remind you of a fine instrument or tool,” said Lyon. “Indeed, the Granite is like that – a precision instrument wrapped in a protective, industrial case.”
