Not just Ford...
Wasn't the V-10 also considered for use in the Ford GT at one point in its development? It would be a pity if this engine is never used in a future Ford vehicle. Incorporate some of the features from the 3.5L V6 or perhaps base it off of that engine and it could truly be one bad mother-shut-yo-mouth of an engine.

 

Maybe the V10 will show up in a Lincoln/Mercury version of the Mustang

 

V10 SN95....drool... They shoulda made it .... drool

 

I believe that article is at least 2 years old. With the resurection of the Hurricane engine, now Boss, I'd say there is no chance of a low deck, high performance V10 mod motor going into production. The 6.8L Boss V8 is intended to replace the current 6.8L high deck V10 truck engine, so I expect Ford to be completely out of the V10 business in a couple years.

V10 engines suffer from higher friction losses than V8s, are harder to get even airflow to all the cyliners and are significantly more costly to manufacture. A 90 degree V10 is not an even firing naturally balanced engine too, which requires a spit rod journal crank (again more cost) and / or balance shafts for smooth running (again more cost). To make a naturally balanced & even firing V10 a V angle of 72 degrees is required, which tremendously increases tooling cost
