Volkswagen (VWAGY -0.30%) unveiled an ambitious new goal this week: VW wants to become the world's leader in "electric mobility," its catch-all term for hybrids and electric cars.

In recent years, VW's leadership has made a habit of announcing outrageous-sounding goals -- and then making them happen. But this is a daunting challenge: Toyota (TM -1.19%) is undisputably the world's hybrid-car leader, Nissan (NSANY -4.11%) has sold more electric cars than anybody, and Ford (F 0.91%) has seen its hybrid sales grow rapidly of late.

Does VW really think it can pass all of these giants -- along with Tesla Motors (TSLA -0.92%), which is on its way to what it hopes will be 500,000 electric-car sales every year in a few years? In this video, Fool contributor John Rosevear looks at VW's ambitious plan -- and at what it will need to do to make this wild-sounding goal a reality.
