Hidden Trick
Do you know that tricky turn at the end of Dinosaur Canyon? Well, that large wall is actually hiding a hidden road which looks like a path to victory. It isn't. It's actually hiding a dead end road with a banner that says:Congratulations, you just lost your sponsors.
If you don't believe me just turn backwards at the end of the pit stop and drive into humiliation!

Extra Car
When playing in arcade mode choose any car. Then play all tracks in order. You must make a record and at the last track you will see the staff names. Then you'll get a new car named Daytona.
