Audi may unveil a new concept at the North American International Auto Show in Detroit. While details are limited, Audi stated their press conference will feature a "showcar (that) underscores Vorsprung durch Technik (advancement through technology)." We're not exactly sure what to expect, but Audi's production timetable seems to suggest the company will unveil a concept version of the next-generation A3 or A6. Other possibilities include the long-rumored R4 roadster and the entry-level Q3 crossover. Audi will also show the new A8 which was unveiled earlier this month in Miami. Worldcarfans.com
