Volkswagen (NASDAQOTH:VWAGY) was the world's most profitable automaker last year, but it's far from satisfied. VW wants to be the world's largest-selling automaker by 2018, and it plans to push its profits up even higher along the way.

In this video, contributor John Rosevear looks at VW's efforts in global expansion -- and how the company's huge new factory will help drive it.
