Detroit 2011: GMC Sierra All Terrain HD Concept Eats Raptors for Lunch
Compared to the Ford Raptor, the GMC Sierra All Terrain HD Concept is a T-Rex. Based on GM’s new Heavy Duty platform, this truck is in a whole other segment than the Raptor and was never meant to be a Baja machine.
Unfortunately, this is just a concept and GMC execs aren’t commenting on production possibilities. What’s more likely is that some of the design cues featured here will trickle down to the standard truck. With tight budgets during the recession, GMC opted to spend all their cash on a new frame and new engine. As a result, the truck is a dud in the looks department. It certainly won’t be, however, once some of this truck’s styling has been adapted.
Combining the standard Crew Cab with the 5′ 8″ box currently not offered on HD models, the All Terrain concept then gets a special front end with a massive front grille, custom matte-chrome accenting and LED lighting. A two-inch lift is also part of the package, with Fox Shox and custom control arms. To help the truck’s off-road capability, it has sculpted front end to deliver a maximum approach angle and the side steps that are retractable as well. In addition, the entire undercarriage is coated in a special hard composite for maximum durability.
Custom 20-inch 8-lug wheels give a real rig look to the diesel monster, as do flared fenders that house a two-inch wider track. Those 20s also help give excellent AWD capability when matched with a set of 35-inch-tall BFGoodrich KM2 “mud terrain” tires.
Under the hood continues to be GMC’s new 6.6-liter Duramax diesel V8 making 397-hp and 765 ft-lbs of torque.
