The upcoming 2011 Detroit Auto Show promises a big bang for all pickup truck enthusiasts. Thats where the halo GMC Sierra All Terrain HD Concept will be introduced to the public. Struggling to compete with pickup market bestsellers - the Ford F-150 SVT Raptor and the Ram 2500 Power Wagon - GM has come up with the golden mean between those two.
The power of the All Terrain concept comes from The Generals 6.6-liter Duramax diesel V8 and six-speed Allison automatic transmission, which sends the 397-horsepower and 765 pound-feet of torque to all four wheels.
The Sierra All Terrains exterior design goes in concord with the beast stuffing and accentuates the pickups hulk power. Versus a normal Sierra HD, ground clearance has been increased by about three inches, width has been bumped up to 73 inches (four more than normal) and the whole package rides on 20-inch aluminum wheels wrapped in 35-inch BFGoodrich KM2 mud terrain tires.
Inside, GM has improved the current GMC Sierra HD cockpit with a Denali-spec design, including additional satin metal finishes and a leather-wrapped dash. A new navigation radio features 80-gigabyte hard drive and DVR-style time-lapse playback, which allows up to 20 minutes of media recording and replay from ground and satellite radio stations.
It remains unclear whether there will be a market for a diesel-powered HD pickup that will probably cost more than $65,000. Still, with the All Terrain concept put into the current or next-gen Sierra HD, General Motors is about to set a new landmark on the off-road map.
