I'll tell you why it, and many other cool concept cars never get built. Americans won't buy them at the price or in the quantity that makes sense for a company to produce them.
Take for example the last generation Focus RS. It works in Europe, but only becuase Europeans are willing to spend more for a small car with performance. The RS would have cost $32-35k US if it had been brought here in production. How many of you would drop $35k on a stock Focus? and I don't mean how many of you would say "I'd buy it if I had money" I mean how many would actually drop the cash right now.
