Drive as S. Hattori
Complete championship mode once to unlock a bonus Japanese driver that is not ranked in the CART-Season or with a Team.

Super Speed mode

Bonus camera angle
Complete championship mode once to unlock a far top view camera angle that resembles the game Micro Machines.

Disable opponents in Championship mode
To disable an opponent in championship mode, just ram the back of his car. If done correctly, his car's back wing will break and he'll be unable to go fast until he reaches his pit stop. You must have the no collision damage option for this to work. Otherwise your car will suffer heavy damage.

Play as Pace Car
For every time you complete championship mode a new pace car will become available to race in ARCADE mode or High Speed mode.
