The picture above is what fueled the speculation, with what's assumed to be a set of infrared projector beams mounted within the headlamp. Said beams would exchange information with a camera mounted on the windshield, then project the enhanced image onto a screen.
We're less than convinced that this is the case, not just because a digital dash would have to be adopted by the guys and gals of Stuttgart, but because it seems contrary to the Porsche edict of over-engineered, gimmickless motoring.
Thanks for the tip, Mike!
