Ford's Fusion has sold so well that dealers in some parts of the country haven't had enough to keep up with demand. A new assembly line should help within weeks. Photo credit: Ford Motor Co.

Ford's (F -1.24%) Fusion sedan has been a big critical and commercial success for the Blue Oval. Its dramatic looks, rock-solid feel, and lush interior have wowed customers -- so much so, that the Fusion's factory has been hard-pressed to keep up with demand.

Ford invested big to up its game, adding 1,400 workers, and a new assembly line to a Michigan factory to make more Fusions. But will it be enough to catch Toyota's (TM -4.46%) Camry and Honda's (HMC -2.99%) Accord? In this video, Fool contributor John Rosevear digs into the numbers -- and tells you what to watch for as more Fusions start to arrive at Ford's dealers.
