The biggest shame of the Silverado Hybrid is that it will only see limited production in a few states. This hybrid version of Chevy's big pickup uses a battery and electric motor not to aid in acceleration, but to run the power accessories when the engine shuts down and start the engine back up. When the Silverado stops for any reason, the engine shuts off ending the need for wasting gas during idle. Once you remove your foot from the brake, the engine starts up again and you are one your way. The generator is also great to plug in an array of items for tailgating or contractor work.
