Virtua Racing is a polygon-based racing game in which you must beat an opponent, who is either human or computer controlled. In the conversion to the Saturn, many new features were added:

7 new tracks, which brings the total number of tracks in the game to 10.
4 new cars, which brings the total number of cars in the game to 5. The new cars are a go-kart, a Porsche 911, an F-160 racer, and a GTP-class car.
A new Grand Prix mode. The Grand Prix mode is a career simulation. You must work your way up from one class of vehicle to next be accumulating points in a series of races.
