Well, the secret is out, and Ford has done all but admit it by going after websites who published the picture. Yes, the glove fits, and he did it.

But lets stay real here... this is obviously just a clay styling buck - so it does not mean that this *is* the final appearance of the upcoming "new" Ford Taurus.
Do note that the roofline is very similar, if not the same. And the overall proportions of the car are the same. And of course a this point in time an all-new Taurus is an impossibility given Ford's financial crisis. So if this is it then it's just a "top hat" restyle (like the new F-150).
The good news is that we know the Taurus will receive the EcoBoost engine - that's already been revealed. But then so will everything built on this platform (Flex, MKS, MKT) as well as the new F-150 and very likely the 2010 Mustang as well. The April 7, 2008 Automotive News notes that the Taurus and Mustang will both go into productioin in "early 2009". I interpret that as meaning that the model year 2010 will be a long one.
