This is a fascinating idea that a colleague and I were discussing last week
Lincoln could certainly use some unique products alongside increasingly well equipped Ford brand vehicles. If Ford were to do this they should follow the plan that Bob Lutz was planning for VL Automotive. http://youtu.be/nfw9DYNZJCs
However instead of a Chevrolet LS9 from the Corvette ZR1, they could do a base model with a higher output 400+ hp version of the 3.5-liter EcoBoost V6 and a flagship with the 662-hp supercharged 5.8-liter V8 from the Shelby GT500 Mustang.
Nobody seem to know what to do with Lincoln, which is just getting over its amazingly dull Superbowl ad failure. What if they merged with another totally-screwed carmaker, Fisker?
