This month, Audi said it will boost spending by two billion euros ($2.5B US) over the next five years, for a total outlay of 24 billion euros from 2014 to 2019. Something like 70 percent of those billions will be spent on new models, technology like "connectivity and lightweight construction," and factory expansion at its plants in Ingolstadt and Neckarsulm.
Despite years of researching any number of standard ICE alternatives, it's becoming clear that different automakers are starting to throw their weight behind their advanced-powertrain technologies of choice.

For Audi, plug-in hybrids appear to be the way to go.
