There is a tussle in the boardroom of Volkswagen AG over the Porsche Cayenne and the Volkswagen Touareg. Porsche is using it’s majority stake shareholding to influence Volkswagen product planning and marketing, especially with it’s joint projects such as the Cayenne-Touareg, two SUVs developed in such close cooperation that alot of people have called the Cayenne merely a dressed up Touareg.

Volkswagen plans to launch an all-new model change Volkswagen Touareg in late 2010, but Porsche wants to launch the Cayenne earlier during the first half of the year. “We aren’t at all pleased with a significantly longer model life for the current Touareg compared to the Cayenne. After all, the vehicles are in competition with one another,” said a high-ranking Volkswagen executive.

“If we can’t come to an agreement at the level of the working teams, the CEOs will have to hammer this out,” said an official of Porsche.
