I found this on the SimBin site while I was looking at Race 07:

"GTR Evolution Announced
SimBin Studios AB today announced the forthcoming release of GTR
Evolution. Developed by the multiple award winning Swedish studio
SimBin Development Team and published by SimBin Studios AB, GTR
Evolution takes GT and WTCC Extreme cars to the Green Hell of
Nordschleife, the holy grail of racing. Available as a stand alone
game and also as an expansion pack for SimBin’s 2007 title RACE 07,
GTR Evolution is scheduled for launch in 2008.
In addition to many other tracks, players of GTR Evolution will drive
the modern version of the monumental track of Nürburgring Nordschleife
along with the Nürburgring GP layout. Dubbed “The Green Hell” by
racing legend Jackie Stewart, the track is revered and feared as the
most difficult and treacherous track ever built.

“As the first PC game developer to get exclusive access to this track
for reference, SimBin has been given a solid ground to work from and
we hope that we will be able to give our fans a real hell, so to
speak”, said Jay Ekkel with a smile, Producer at SimBin Development
Team AB.

GTR Evolution for PC comes with 22 GT car models in 3 different
classes plus a selection of exclusive production cars. Further to this
SimBin adds WTCC Extreme, tuned concept cars based on the FIA WTCC
cars.

“With rear wheel drive, extended body-kits and over 600hp the WTCC
Extreme cars will give the GT cars a run for their money, said Diego
Sartori, Creative Director at SimBin Studios AB.

GTR Evolution will be available as a stand alone game including all
RACE 07 content, all in all 49 unique cars in 12 classes with over 500
variations and 19 tracks in over 40 different layouts including the
new and legendary Nürburgring Nordschleife. A GTR Evolution expansion
pack for existing owners of RACE 07 will also be available.

“This is the biggest game ever from SimBin and a must have for all
gamers and we hope that GTR Evolution will satisfy all race fans since
it is packed with a broad variety of cars and new features that should
attract the gamer that wants to have it all in one high quality game”,
says Henrik Roos, CEO of the SimBin Group of companies.

Scheduled for launch in 2008, GTR Evolution is distributed by Atari in
Europe, Viva Media in the US and Akella in Russia. The release is
scheduled for 2008 with detailed info to follow."

They also mention an STCC game in other news but I don't know if this
is the same thing.
