Both Autoblog.nl and Saabunited.com believe that the source of these images is Saab itself. We're not so sure. The images are far from perfect (is that a scratch on the front bumper of the 9-5 sedan?), showing two drawings that need some finishing touches. Most recently, the wagon was seen under a tight-fitting cloth cover teasing us with an idea of what the vehicle will look like.
However, what the artist seems to have been accurate on is the overall shape of the front bumper, including headlight placement, air intakes, grille shape, and fog lght location. Also, the wheels appear to be fairly close in design to what Saab has included on their teaser car.
Comparing these pictures with the rendering, we think we can spot a few differences. The rendering does not appear to have a steep enough angle just over the rear headlights. Rigidity looks to be key in the back end of the covered up car, as opposed to the smoothness seen in the drawing. Also, the rendering shows a roofline that plunges down at the back quite a bit more than the concealed 9-5 wagon, which shows a flatter roof.
The car should be available with a mix of four and six cylinder engines (petrol/BioPower) and a four cylinder diesel. The six cylinder diesel that was planned for the car was cancelled by GM.
