The concept is powered by a 4.9L version of GM’s small-block V8 engine that features fuel-saving technologies such as direct-injection technology and Active Fuel Management. The V8 engine delivers 326 hp. 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.

Press release

GMC unveiled the Denali XT concept at the 2008 Chicago Auto Show. It offers a 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, including 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.

“Like all GMCs, the Denali XT is functional and capable, but it blends those traits with a more efficient, sporty driving experience,” said Jim Bunnell, GMC general manager. “It is a vehicle that exemplifies GMC’s engineering excellence, as well as GM’s commitment to hybrid and advanced technologies.”

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.

“Denali XT is about working hard, playing hard and enjoying an active lifestyle,” said Bunnell. “It is the same philosophy that has helped make the GMC Acadia crossover a huge hit with consumers.”

Dramatic design statement

A muscular form and wide, firmly planted stance give the Denali XT a confidently capable road presence. Mini Mini mal overhangs, large wheels, sleek headlamps and a low roof profile deliver an aggressive, performance-oriented appearance.

“It is a robust yet tailored design statement that is unlike anything else on the road,” said Ed Welburn, vice president, Global Design. “It has the youthful look of a custom automobile that incorporates the capability customers expect from a truck.”

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. Flared fenders accentuate the wide road stance. The stance is also enhanced when the Denali XT is lowered on its air-adjustable suspension, which creates a sleeker appearance that simultaneously improves aerodynamics. Large, bold 23-inch wheels and custom Kuhmo tires complement the Denali XT’s stance.

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 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,” said Warrack Leach, lead designer.

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 interior illumination was supplied by Osram.

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

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 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.

Also, 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 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.

The specific characteristics of the Denali XT allowed the synergistic evolution of GM’s small-block V-8 and two-mode hybrid beyond the recently introduced in GM two-mode hybrid products, such as the GMC Yukon GMC Yukon Hybrid and Sierra Hybrid. During this optimization process, additional powertrain technologies have been integrated, including Active Thermal Management, which transfers thermal energy from one driveline component to another to improve efficiency; and a high-efficiency axle configuration, which fundamentally reduces the losses normally associated with conventional axle configurations.

The integration of the advanced internal combustion engine technologies and two-mode hybrid system on the Denali XT reinforces GMC’s Professional Grade position as a brand that continues to exceed customer expectations.

Big, but not bulky. It’s sporty instead. I like the silver grills at the front and the big rims is the perfect set for this kind of vehicle.

Surprisingly, nothing has gone wrong with GMC Denali XT except its giant 23-inch wheels. But the features and the styling didn’t impress me at all.

Did they already put it on the market? Well, I’m just curious if what’s the market priced of this. Anyway, I am hoping also that this awesome fancy vehicle is not on an electric motor.

This one of the concept that attracts me much. I like the classy and luxurious type of the car. Much styled and sporty looking for its detailed features. Also I’ve noticed the eye-catching alloy wheel.

You are right GenevaSanMiguel I had also the same observation but I must say that the styling and the platform of their car is quite impressive for me.

I just found out that almost GMC cars had a big exhaust which is sometimes not suited on their car, like on this Denali XT.

The same bashes are praising the huge, non functional at street speeds, wing on the Nissan GTR a few blogs down!

Actually Aussies have been building the Ute style since the 1930’s.
This body style would be pretty unfamilar to a lot of Australians, as it has been done as a clone of a US Pickup, our Utes are sedan based.

Honda’s Ridgeline has this kind of unibody construction and has been available for a while. I bet this "concept" even has a "novel" in-bed lockable trunk ... just like the Honda. What a concept! Ten years ago.

thats a realy cool auto
take it out in the market GMC
it bery cool

Like I read in another comment, make the bed a full 48" between the wheel well’s, makes real sense. Other than that this vehicle shows us how great the future of changing designs can be when someone strikes the right vein. I hope GM puts this into production immediately and i think they will be pleasantly surprised at the response they will be getting this year with the utility of thier hybrid line-up.

I was ready to put it on my short list before I looked at the specs. At 47.5 inches wide, they’re missing by 1/2" the ability to bring home a sheet of plywood from the hardware store. Big mistake! That’s what trucks are for. Hopefully they will correct this oversight that will keep many buyers away.

love this vehical, it’s definitly a sassy girls dream.

Sweat Truck I want one.......

Awsome American Iron! Technology on it sounds great! 326 HP!! Please build it GMC !!!

I say that no sand anywere shld be aloud to own an american made Pickup!!!

of i would like to be the first one in the mideleast tack this car

in Saudi arabia

chop top always look great, 22 inch wheel looks great as well, but try to drive a car with chop top and razor thin tires for more than 10 miles and you will regret to look good smiley
