GTR Evolution is an expansion pack to Race 07 developed by SimBin, published by Atari in Europe and Viva Media in the United States. It was released worldwide for digital download on Steam on September 1, 2008. It is also available for purchase in many countries in a DVD boxed version.
Other SimBin titles have a large following of dedicated sim-racers and modders. This means that there is a large number of mods (modifications) and tracks available for previous SimBin titles which should be easily modded (modified) to the new game. All modifications available for Race 07 will work for GTR Evolution.
