Yeah and I assume that the SVT was in the works but there are three reasons I can think of for holding back
a) have something to intro at New York
b) intro it with the SVT Cobra which may show up in a few days ;)
c) final decision for production wasn't made yet (better to announce products that will come out rather than announce and then change your mind [see GM]).
I actually think the white sport trac concept was the same physical vehicle as this adrenalin, with a repaint and some new bits to reflect the different model. Since the first model was a pure concept, they could get away with the wilder look to represent the base vehicle since the public would expect a tamer stock vehicle. With this adrenalin, Ford's made a clear statement that SVT will build it. I have no doubt that some things will change but I think the overall concept is very representative of what will be sold. With the exception of the shaved handles, everything looks production ready, from the interior, to the plain looking (though two-tone) seats, and the switchgear.
