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.
