2014 Silverado Spied!
 

Although it's heavily camouflaged, the Silverado is recognizable. We can also tell that this camo-ed up truck is the start of the next generation of Silverados. There isn't a whole lot of information out yet but it should be sporting a small-block v8 engine designed for better fuel efficiency and more power. Also, the new Silverado appears to have a bigger interior.
