Computer Games Magazine has posted an interview with Wolfgang Duhr of SimBin, about GTR.
Computer Games Magazine: "What types of tracks can people expect to see in the game?"
Wolfgang Duhr: "Well, the game is based on the FIA GT Championship and the tracks one sees in the game is therefore the tracks that were visited by the series. There are ten of the most famous tracks in Europe and some of them are also GP-circuits used by Formula 1. Most racing fans have heard of all of them."
