The GMC Denali XT is a small, unibody construction, hybrid powered Sport-Utility Truck (SUT).

The design and layout of the Denali XT concept is inspired by car-chassis based pickups like the Chevrolet El Camino. By using a unibody construction instead of the conventional body-on-frame method commonly used for trucks, the Denali XT manages to remain relatively lightweight (giving better fuel economy) and offer superior handling characteristics.

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 the four-wheel independent suspension that gives the Denali XT its performance feel on the road.

The design and construction of the GMC Denali XT concept was undertaken by Holden Design, within the Australian arm of GM's global design and engineering network. The concept is characterised by a muscular body and wide, firmly planted stance. Minimal overhangs, 23" wheels, sleek headlamps and a low roof profile help 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. 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.

Inside, the four-seat Denali XT concept 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, center console armrest and door inserts.

"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.

Power for the GMC Denali XT concept comes from a 326 horsepower V-8 4.9 litre E85-capable engine with Active Fuel Management (a system which deactivates half of the engine's cylinders when they are not needed). Paired with the V8 power is a two-mode electrically-variable hybrid transmission which helps to reduce fuel consumption further by smoothly altering the gearing to allow the engine speed to remain at its optimum rpm when cruising, and when extra power is needed electric motors in the transmission provide the extra grunt. For low speed city driving the electric motors provide 100% of the Denali XT's power.
