To access the cars, players must do the following:

On the Main Menu Screen tap these buttons in order:
RIGHT, RIGHT, LEFT, SQUARE, UP, L2, L2, R1

This unlocks all of the cars/tracks and allows you to select from the fastest cars on the lot.

At this point the easiest way to unlock the SoundMAX and SPX Cars is to:
- Enter the SF Drag Race
- Select the Dodge Concept Viper
- Set a new time record (not difficult with this car.)
- Enter: "SOUNDMAX" in the Name Entry Screen.

NOW the 3 extra Cars (Jaguar XK-R "SoundMAX SPX", Jaguar XK-R "Analog Devices", and the Aston Martin db7 "SoundMAX SPX") will appear on the Car. Select Screen in all modes except Story Mode. Select the cars, and prepare to race!
