Uses the Sportscar GT physics and graphics engine, as well as menu system under license. Had this released two years earlier it would be a solid simulation for that era, but with NASCAR Racing 4 releasing the previous year it was basically out of date upon release. It has a plentiful supply of game-breaking bugs, and generally offers a poor experience.
The only positive aspect of the simulation is the track list, which includes a number of classic short ovals that in some cases no longer exist.
