Forget what you've heard about delays with the Model X. Tesla Motors (TSLA 0.72%) shareholders can expect their company to introduce at least one game-changing vehicle in 2014. Only it'll be Mercedes-Benz that builds the car.

And that's good news, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova. A small, but growing, portion of Tesla's revenue is derived from creating fully electric drivetrain systems for other car manufacturers, including Mercedes and Toyota Motor (TM 0.54%). The Electric Drive looks to be Mercedes' first attempt to make good on its relationship with, and 4.3% equity stake in, Tesla.
