Bonus Short:
On the main menu if you wait until the counter on your DVD gets to 1:07 in the bottom right hand corner the Dinoco 400 logo will appear. Go to the bottom choice on the menu (Set Up) and hit the right arrow. You will unlock a short cartoon with Cars characters in the Pixar short "Boundin".

Bonus Feature:
On the Main screen when you first insert the dvd, "Lightning McQueen" is going around the track and you can see a gold trophy go past his face about 3 times (the trophy flys past him pretty fast). Well after several times a little flag icon appears in the bottom right hand corner of the screen. CLICK on it and you will see a short little bonus feature.
