Just the Facts:
  • The 2011 GMC Sierra All-Terrain HD Concept ups the off-road ante for the full-size truck and hints at the future design direction of GMC trucks.
  • It gets an enhanced suspension, increased ground clearance and a wider track.
  • While not giving the green light for production just yet, GMC says that while it's "strictly a concept, it is a pretty realistic one."

DETROIT — In a refreshing change of pace from what promises to be a "green" 2011 Detroit Auto Show, GM on Thursday took the wraps off the beefy GMC Sierra All-Terrain HD Concept. The body-on-frame concept truck — a serious off-roader — is designed to take the new HD platform to "the next level," says GMC.

GMC isn't confirming that the concept is bound for production, but it appears to be fairly ready for the road. "Although it is strictly a concept, it is a pretty realistic one," said Lisa Hutchinson, GMC product marketing director in a statement.

GMC said the four-wheel-drive concept, with its striking streamlined look, hints at the future design direction of GMC trucks.

The concept is equipped with the new, production 6.6-liter Duramax turbodiesel V8 linked to an Allison 1000 six-speed automatic transmission. It delivers 397 horsepower.

The new 2011 Sierra HD underpins the concept, which is shorter in overall length than production Sierra HD models. The concept gets an enhanced suspension, increased ground clearance and a wider track. The concept gets a unique 5-foot, 8-inch crew cab/short box body style. Other details include front and rear jounce shocks, and 35-inch BFGoodrich "mud terrain" tires mounted on 20-inch machined aluminum wheels. The streamlined bumpers have a practical bent and are designed to enhance approach and departure angles.

The rear of the concept has lockable, lighted storage compartments and a non-slip rubber pad on the tailgate. The composite bedliner has a "circuit board" pattern.

The concept has an Iridium Metallic paint job. It is a dark charcoal color with a reddish tint. The cabin gets stainless-steel mesh and satin chrome trim and a new navigation radio that GMC says "previews future radios to be offered in GMC vehicles." It provides greater storage of music from portable devices and features a "time-lapse playback," which allows up to 20 minutes of recording/playback from the AM/FM/XM stations.
