Here's a video of the upcoming 2012 Porsche 911 Carrera shot on the road near the Zuffenhausen factory in northern Stuttgart. We're not sure whether this is a cloaked Porsche production teaser or an independent spy video.

We get to hear that new Carrera sound as it is emitted from that quad-piped exhaust, although, the camera car is a Panamera Turbo (see reflection at 4:08) so one has to pay attention to make the distinction.

Also, have a look at those taillights as this blue-green metallic 991 prototype goes through the tunnel.
