Audi readying a Q6 to go up against the BMW X6?Autoweek is reporting that development started on a performance crossover SUV aimed squarely at the X6. Unlike the X6 when it launched, this will be a 5 seater. It will most likely be based on the Porsche Cayenne platform which has us intrigued. Oh, and an RS Q6 model may be coming which will be designed to compete with the X6 M using the new 4.0 turbo V8. Hey, bring it on.
