Both recent interviews indicate that this new model will be bigger than the Tiguan, and Thul's comments confirmed that it would be a three-row, seven-passenger model. Even more detail: Thul said the new model would be aimed solely at the American market as more of a minivan replacement than an off-roader, so it is likely this is going to be an entirely new model rather than a stretched version of the Touareg. The Straightline Blog indicates this crossover could be based off the US-spec Passat which matches up with Winterkorn's earlier comments mentioning the possibility that this new vehicle is the best candidate to be built at the Chattanooga assembly plant.
Another upcoming model that likely won't be headed to the US is a subcompact crossover that will be positioned below the compact Tiguan. We expect to learn more about these new crossovers over the next year, but both should really help VW attain its goal of topping General Motors and Toyota to become the number one automaker around the globe by 2018.
