It appears as if GM has some explaining to do when it comes to the oh-so-important Chevrolet Volt. In layman's terms, various sources are showing up to call out the General about how, specifically, the Volt is motivated.
GM says the gasoline engine doesn't officially move the wheels, and the critics say at some point it does, which if true, means the Volt is a plug-in hybrid (albeit, an advanced one at that) and GM has been lying to us all along.
