GMC Sierra All Terrain HD Concept
GMC SIERRA ALL TERRAIN HD CONCEPT TAKES HEAVY-DUTY CAPABILITY TO NEW GROUND
DETROIT -- The GMC Sierra All Terrain HD concept is an exploration of
heavy-duty truck capability combined with greater off-road versatility. It
is highlighted by a bold exterior design, enhanced all-terrain suspension
and premium details expected of a GMC -- all designed to enable greater
access to off-road destinations.
The new 2011 Sierra HD underpins the All Terrain HD concept, with a
modified, production-based 4WD chassis and the Duramax diesel/Allison 1000
six-speed powertrain. The enhanced suspension and unique body dimensions,
including increased ground clearance and wider track, as well as greater
approach/departure angles, deliver off-road capability while maintaining HD
levels of payload and trailering capacity.
"The Sierra All Terrain HD concept takes GMC's outstanding new HD platform
to the next level, marries it to the legendary Duramax diesel/Allison
transmission, and provides a heavy-duty expression of GMC's premium All
Terrain package," said Lisa Hutchinson, GMC product marketing director. "It
delivers the exceptional capabilities of the Sierra HD -- hauling, towing
and performance -- and applies them to the toughest driving environments.
It's the ultimate professional-grade tool for construction crews, ranchers
and adventurers whose activities aren't limited by where the pavement
The Sierra All Terrain HD features a unique five-foot, eight-inch Crew
Cab/short box body configuration that supports a wheels-at-the-corners
proportion. Shorter in overall length than production Sierra HD models, the
concept's dimensions contribute to greater approach/departure angles.
Additional off-road elements include:
* Wider, 73-inch (1,853 mm) track for greater stability
* Approximately 3 inches (76 mm) greater ground clearance
* Custom front upper and lower control arms
* Specially constructed Fox off-road shocks with remote fluid reservoirs
(integrated in the wheel house liners)
* Front and rear jounce shocks
* Electronic front stabilizer bar disconnection
* 35-inch-tall BFGoodrich KM2 "mud terrain" tires mounted on 20-inch
machined aluminum wheels
* Full composite underbody protection.
"The capability-enhancing attributes of the Sierra All Terrain HD build on
the already outstanding capabilities offered in the all-new production
Sierra HD trucks," said Hutchinson. "Although it is strictly a concept, it
is a pretty realistic one."
From every angle, the All Terrain HD looks the part of a dedicated off-road
performer, with bold, accentuated features complemented by a wide stance
and tall profile.
Streamlined bumpers are designed to enhance approach/departure angles and
incorporate frame-mounted recovery hooks -- with integrated skid plates. A
large, airflow-optimized grille maximizes cooling in tough conditions,
while a forced-induction hood delivers more air to the Duramax diesel
"The design of the All Terrain HD is an expression of its capabilities --
strong, functional and absolutely professional grade," said Carl Zipfel,
design manager. "We're excited about the design elements and exploring how
they could apply to future GMCs."
Large fender flares stretch away from the body to cover the 35-inch-tall
BFGoodrich tires. At the rear, the cargo box features lockable, lighted
storage compartments, along with a number of tie-down cleats, including a
pair in the bed floor and two on each side of the bed. A non-slip rubber
pad is used on the tailgate, while two special compartments inside the
cargo box provide access to a 110-volt power outlet and air compressor. A
composite bed liner with a unique "circuit board" pattern provides a
protective cover for the bed.
Motorized, deployable assist steps for the cab and cargo bed make it easier
to enter and exit the All Terrain HD, while maximizing ground clearance
during off-road driving. It also incorporates a number of industrial-grade
lighting elements to provide greater visibility for safer driving where
stars may be the only other source of illumination. The lighting details
* High-intensity LED headlamp, taillamp and fog lamp lighting mounted in
impact-resistant composite housings and featuring edge-lit illumination
* High-intensity LED park and turn signal lamps
* Smooth-appearance front marker lamps integrated behind the top edge of
the windshield glass
* Integrated center high-mounted stop lamp and rear marker lights mounted
at the top edge of the rear window glass
* LED floodlights for the cargo bed and assist steps.
