2011 Detroit Auto Show Preview: GMC Sierra All Terrain HD Concept

Follow Nelson

Ford's Raptor is the undisputed king of production off-road truck awesomeness, but it may soon have a challenger, previewed here with the GMC Sierra All Terrain HD Concept. Bigger, diesel-powered, and suitably brutish, the All Terrain HD is at this point, "strictly a concept," however.

According to Lisa Hutchinson, GMC product marketing director, the truck isn't aimed at Baja-style high-speed duty like the Raptor, but rather towing and hauling in harsh offroad environments--it's still a Sierra HD, but with a dirtier side. That's still an impressive mix for a 397-horsepower, 765 pound-foot turbodiesel V-8 capable of towing 13,000 pounds and carrying 2,700 pounds in its bed.

The All Terrain HD is able to do all of this thanks to added off-road features including a wider 73-inch track, three more inches of ground clearance, custom suspension control arms, remote-reservoir Fox off-road shocks, electronic front stabilizer bar disconnect, full composite underbody protection, and 35-inch-tall BF Goodrich MK2 mud tires on 20-inch aluminum wheels.

As noted earlier, though, you shouldn't get your hopes up: you won't likely be buying one of these, ever. "Although it is strictly a concept, it is a pretty realistic one," said Hutchinson.

  1. Seems as though the Ram Powerwagon is more of the target than the Ford Raptor.
    Notice the bed rail box, similar to the Ram Box.

  2. Has Obama taught us anything, even though planes are the worst offender GM say what hey can do and that's it! Time for natural gas injected diesels (and bio fuel air planes) at the very least, now that would be a concept!

  3. The new HD is a interesting concept because it is a "catch all" idea that focuses on looks and ability. I think this will create a lot of hype. The ford Raptor is in its own world geared more towards Baja So you cant really compare the two. The RAM Power Wagon is pure strength and ability but missing Diesel power but for good reasons. The GMC appears to be the "Hollywood" of the three but will lack strength in the front axle/suspension for extreme off road use due to its independent style design coupled with too much torque from the Duramax and the weight it will have to bear over it. I also feel the balance will be upset, a issue on the rocks and trails due to the diesel power plant. All and all I would like to see this be a production option in the near future and keep the trend of super trucks going! I would love to get a chance to drive one and really put it to the test. I still think "overall" The RAM Power Wagon cannot be beat! Good luck GM.

  4. GMC has had the better looking truck, now put the Yukon XL body on that frame! The Yukon XL is the last to get the power it needs to pull. The 1/2 ton p/u can pull more than 3/4 ton Yukon! Come on GM HELP!!!!!
