A coupe in that size from Ford would be called a MUSTANG. I don't think it will happen as the only advantages to a Fusion coupe would be the insurance reduction & more rear seat room. 4 doors with folding rear seats has too many positives - might throw in a 5 door maybe.
Now if they put the Mustang V-8 & RWD in the Zephyr coupe....

Hot Rod Lincoln time!
I also saw this Chinese prototype in one of the links from that page. Has potential...
