German Showdown Tournament: Go past barrier:
At the very bottom left side of Hot Pursuit mode is the German Showdown Tournament. In race 3/4, as soon as the start timer counts down, go backwards to the cement barrer. Go to the right side of the barricade (at the bottom), then press the car reset button (Z). If you were close enough, you should end up on the other side of the barrier. Turn around and go the other way. After you cross the gap on the map, your status will change to first place. Keep driving and you should find a huge unfinished "mountain". Stay at the dead end and you will see your opponents flying through. Some how they have gotten through the blocked off bridge that appears later in the stage. To get out, go to the opposite part of the barrier and press Z. Note: this may require a few attempts.

Short Cuts
Short cuts are an important way to win, but sometimes they slow you down. You need to make sure that when you take a short cut that there isn't any dirt, because that slows you way down. Also make sure that there isn't more turns then the long way.

Clean Race
There will be two objectives you will have to do to unlock two kinds of cars. These two involve clean racing. For a clean race, avoid hitting any object that inflicts damage on your car, such as hitting another car, a wall, etc. Hitting road signs, going offroad, or landing very hard on big jumps are excluded since those do not do any damage
