Forget the Trademark Debate - Audi Is Coming Out with an SUV? I guess they're responding to the success of the Touareg. The AP reports that "Audi, Nissan Battle Over 'Q' Model Names." From the article:

That prompted Nissan to file a lawsuit in federal court Tuesday. It says Audi's use of Q "is likely to cause confusion, deception or mistake among customers."
