2011 GMC Sierra All Terrain HD Concept (2011 NAIAS)

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 ends."

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.

It's true ford guys are loyal but ford has marketed that way. They have an unreliable product, so you have to turn it in and buy another one in 3-5 years. The loyalty keeps making them rich. Keep on buying smart guys.

@xKillaCr3wx lol maybe for speed, but if you tried any serious rock crawling with a raptor, it would just tear it to pieces, cuase thats all its got, speed. this thing has plenty of tourque, and could kick any raptors ass in a crawl, hands down
