The idea of this addon is bringing TORCS back to life. A very simple game that anyone can install and play.
To install this addon you need to extract the .rar file into C:\Program Files (x86)\Torcs\cars, move the .wav file into C:\Program Files (x86)\Torcs\data\sound and then you are ready to play.
Again, car model and sound are owned by Polyphony Digital. The model has been downloaded from here Gamemodels.ru.
