We're not sure how legit this is, but it's always fun to speculate, right? Autoblog reader Swade sent us a link to Trollhattan Saab, which says this might be the car GM unveils in Geneva on February 27 to show the future direction of Saab's styling. The Aero-X, as it's called, is a design study that supposedly sits on its very own unique architecture (likeness to the Saturn Sky, then, must be purely coincidental). The 400 horsepower spit out by the alleged 3.0L twin-turbo V6 under the hood will haul the vehicle via all four wheels if the "X" designation is any indication. Depending on public reaction to the vehicle, word is that it could be built on a shortened Epsilon II platform.
