The manufacturer is currently asking the VW Dealers if they wish to be part of the initial Touareg Hybrid launch. Some Dealers may elect not to participate – it's basically their choice. Those that "opt in" will be required to purchase some special tools and to train their technical staff on the systems unique to the vehicle through VW's specialized training class or classes.
As soon as pricing is announced, it will be available here – along with any specifications made available. Details of the driveline, EPA MPG, Base MSRP, Options, Colors, and more will all be available right here on Hybrid VDub.
Here is a picture of the eDrive motor as published in German.
