Wish GM would offer a full-size truck built explicitly for off-road exploits? We do too, but this Silverado ZR2 concept, unveiled at the 2009 SEMA show in Las Vegas, may be as close as we'll come to seeing such a model in the flesh.
To start, GM fitted the Silverado with a 4-inch suspension lift, bolted on 20-inch BBS wheels, and gave the ZR2 35-inch off-road tires. As a result, the ZR2 has quite a tall stance, but little of the suspension capacity found in Ford's off-road F-150 Raptor. Power comes from a supercharged LS-series small-block V-8 crate motor, which reportedly throws down a solid 550 hp.
In order to help save weight, a number of body panels - including the hood, fenders, rocker panels, and tailgate -- have been crafted from carbon fiber. Designers left the hood and tailgate bare, giving the truck an interesting two-tone look. Carbon fiber also makes an appearance inside the ZR2's cabin, accenting the door panels and instrument panel, while seating surfaces have been trimmed in a mixture of black leather and suede.
We've no idea how serious GM is about putting a truck like this into production, but we know at least some parts of the ZR2 will live on in future Silverados. According to Brent Dewar, vice president of Chevrolet, a number of components "are being explored for possible inclusion in upcoming models," includes the larger grille.
