Sure, GMC knows trucks, but it looks as if it's learning a thing or two about being environmentally conscious as well though.

The GMC Denali XT concept is not only extremely stylish, it uses GM's two-mode hybrid propulsion system for what the automaker says is up to 50 percent savings on fuel compared to other similarly-sized trucks. For the first time with GM's hybrid system, it can also run on E85 gasoline. The engine itself is a 4.9L version of GM's small-block V-8.

And again, this concept fits the profile of a performance-minded sport utility truck (SUT), with a light unibody structure, height-adjustable suspension, large 23-inch tires and wide stance with a generous wheelbase.

As Ed Welburn, vice president, Global Design puts it: "It is 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."

The capability comes in the form of a four-seater with an extendable midgate, fold-flat rear seats, and a 3,500 lb. towing capacity.

The Denali XT's interior features instrumentation with 'floating' red-illuminated numerals backed by surface chaplets in the clusters and a large integrated vehicle interface screen. GM says that the high-cowl vehicle architecture allows the distance between the front and rear occupants to be smaller, without compromising knee room.

The concept uses a four-wheel independent suspension that GM says gives it more of a 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, while the rear has a four-link suspension design that uses coil-over shocks and a decoupled stabilizer bar to enhance cornering control, reduce body roll and optimize longitudinal compliance.

The 4.9-litre V8 engine produces 326-horsepower and also uses cylinder deactivation when less power is needed, further improving the concept's fuel efficiency.
