The original STCC game was made by Digital Illusions in 1999 and was published by EA. In 2000 the sequel, called STCC 2 was released, with better graphics, full 3D cockpits and Carl Rosenblad, a Swedish real life STCC driver as consultant for the physics. Again, this was a product of Digital Illusions and it was published by EA.
These days Digital Illusions is called DICE and they are more or less owned by EA. They have since long abandoned the racing genre (last was Rallisport Challenge in -03) for stuff like Battlefield and Mirror's Edge.
I was at Karlskoga for the real life STCC event this weekend and tried STCC - The Game. It's obviously the same physics engine as Race-07, but I will get it anyway. First of all, it has the Swedish tracks and cars, second of all, it will feature Camaro Cup
