Actually, there have been two TT-based shooting brake concepts from Audi over the years. This is the first, which debuted at the 2005 Tokyo Motor Show where it served a dual purpose. The obvious mission was to explore a slightly more practical TT hatchback, though that role was already covered by the Audi A3. The other mission was to preview the new look for the second-generation TT in a wrapping that would garner a bit more attention.
