More and more Videos of the Panamera are appearing on the net, this one from the guys at ZeroToHundred.com clearly shows the car for what its worth.
The standard model will be powered by a modified version of the 4.5-litre V8 used in the Porsche Cayenne, while there are reports of a cheaper version powered by 3.6-litre V6.
Rumours floating around the internet also suggest a Hybrid version is in the works (alongside a Hybrid Cayenne). There is also a possibility the V12 diesel engine from the Audi Q7 could one day find itself in the Panamera.
You can find another video of the car here. It is a Porsche, but it really doesn't stand out the way we thought it would.
