The 9-3 Griffin will be available in two different flavours, The 9-3 Griffin and the 9-3 Aero Griffin.
Here are the two different fascias.
First off all the Aero seems to get turbine wheels, and the normal 9-3 not. Then the lower Grille is different and the Aero has some chrome details in the Fog lamp pods.
And if you take a better look you will see that the Aero has a chrome line on top of the windows, it is only a partial line like the 9-5, but this time is the upper line. I got the impression that it reflects the front signature lights, 9-3 above the light, 9-5 below the light.
Thank you to Patrik B for the hint.
