While most automakers take their new prototypes out for a testing session with hopes that no one will notice them, Chevrolet->ke199 has decided to pitch us some official spy shot footage of the next generation Silverado pick-up. Gotta love when automakers go against the grain like this.

GM engineers are putting the next generation Chevrolet Silverado through the final paces at the company’s proving grounds in Yuma, Ariz. This water test is part of a rigorous product validation program that has helped make Silverado the most dependable, longest lasting full-size pickup.

The current Silverado->ke1787 has remained unchanged since 2007, but for the new generation, things will change significantly. As you can see, the prototype is heavily camouflaged so it's pretty difficult to see what's new, but as for the engine, rumors say that Chevrolet will use a new 3.6-liter V-6 engine with 300 HP, but a small block V8 is also under development.

The new Chevrolet Silverado will start production in 2013.
