The V-8 Touareg will be priced at $40,700 USD. At 310 hp this is a significant competitor to the Cayenne S. For $15k less!

Also, the Audi Pikes Peak Quattro is built on the Touareg/Cayenne platform. It may, or may not, be built and, if built, may, or may not, be built on this platform. However, it does give you the idea that VW plans to make maximum use of their development investment.
