At TGS the platform holder revealed Mario Kart 7 will automatically exchange player ghost data when other Nintendo 3DS systems nearby, allowing you to virtually race against other players.

Mario Kart 7 players will also be able to use StreetPass ghost data to find players during online play, Nintendo said.

Metal Mario and Lakitu - who's finally jumping off his cloud and in to the race - are also confirmed as additional characters.

Mario Kart 7 will release on December 2 in Europe.
