So what makes the GMC Sierra Pickup Truck a Hybrid? Well it is the way that it uses both a gas engine and an electric motor as this helps the environment which has to be the most important factor here
So you are wondering how it all works well the gas powered runs while you are driving around at normal speeds and is always charging the 42 volt batteries but when you slow down or come to a complete stop then that is when the 14,000 watts motor takes over everything gets quite from there once you pull away and get going again then the gas engine kicks in again
This is going to be more widely used in the future and the Sierra Hybrid Truck also uses a flywheel alternator system which is more aggressive in the way that it uses it idle and stop feature and so you are rewarded with even better fuel consumption

Another great feature in the GMC Sierra Hybrid is the fact that they are generators on wheels, what you have are 2 x three pronged plug ins that are located under the rear seat and another two at the rear of the bed, these 12 volts that can supply 20 amps of power are ideal for running an electric saw or other Diy equipment or maybe you need to plug in a laptop either way this is such a great feature that more cars should have
