Elon Musk, CEO of Tesla Motors, has "challenged conventional wisdom in 2013," says Nightly Business Report and that's precisely why Musk has been listed a 2013 Difference Maker.

Though Musk has his critics, few would argue that there's a single man in the US that has evoked as much change as he did in 2013.

He's challenged the US dealership model head on.

He's attacked the media for its uncalled for coverage of Model S fires and he's even shown the world that a startup automaker can turn a profit.

Musk will face more challenges in the years that lie ahead, but in 2013 Musk proved that he's up to the task of heading America's newest automaker and that overcoming challenges is perhaps what he does best.

A Difference Maker?  We'd say so.
