What is the nintendo wii competition in Germany where you can win the audi?

I don't even know what model audi it is, but the competition is where you go to a certain city and compete in some kind of Mario kart race, and then if your that day's winner, then your picture is put on nintendo's website, and you can win some audi worth 60,000 euro in the finals which are in october.|||Idk.. I just wanted to get 2 points for answering. SORRY! Look it up on google for best anwers though.
