According to a report by Carbuzz, the news comes from a conversation with Hein Schafer, Volkswagen USA senior vice president for product marketing and strategy. In short, he said VW is constantly looking at options for a more efficient engine with more horsepower.
Does that mean VW has pulled the trigger on a Tiguan GTI? Well, it is a rumour after all, and there have been pictures of a full-fledged Tiguan R model testing at Nürburgring lurking around on the net, so the possibilities are there. Plus, other German brands have a high performance version for all their SUVs, so it would only be logical for VW to think along those lines.
