Single Race mode is a mode where a player can choose a track and car to race against 5 AI cars of similar class. Once Single Race is selected and a difficulty (Easy/Normal/Hard/Pro) is chosen, the player is presented with a selection of tracks. At first, only the first six circuits are available. Other circuits are unlocked, 5 or 6 at a time, on successful completion of the previous set of races. A full breakdown of these circuits can be found here. The player may then choose from a number of cars, organised by class (C/B/A/S/R) (see Car List) or choose from their own Career mode garage or a garage stored on a memory card (see Load Garage). The race then begins with the AI driving vehicles of similar class as the player.
