"Speaking with The Wall Street Journal, Ford global manufacturing chief John Fleming said the Continental would be built at Ford’s Flat Rock Assembly Plant in Michigan. The plant is currently responsible for the Mustang and Fusion, and adopting Continental production shouldn’t be a problem as the new sedan has been designed around a stretched version of the Fusion’s CD4 platform."
While it is likely to be built on the CD4, there is no more evidence of that than for it being built on a stretched Mustang platform, so it is NOT confirmed to be a CD4
