Effects of fracking on North Anerican auto market

I just read a artical about energy costs in Germany skyrocketing resulting in several companies moving operations to the US due to LOWERING energy costs including BMW. I thought it would be a good time to get youalls opinion on the matter and how lower energy costs and a overabundance of energy here will effect the auto market. Statements conclude that by the year 2020 the US will be by far the largest economy that gains energy independence and become one of the worlds largest producers of energy and exporters (if the law makers get the ban on exports lifted) a result of the OPEC crisis 4 decades ago
