It looks like although the Porsche Panamera will use the same basic engine and drivetrain as the VW Touareg hybrid and Porsche Cayenne S hybrid, it will be rear wheel drive only. This is done to save space and weight. 0-60 is only 5.5 which is still pretty fast, certainly excellent for a hybrid, but slow for a new Porsche. Check out the blog postings for more on this engine/drivetrain system. Cliffs: supercharged 3.0L V6 combined with an electric motor between it and the 8 speed transmission. Electric only driving is possible for a few miles under a certain speed and it can coast with engine off at up to highway speeds.
