Washington D.C.: Faster stunt driver mission completion

On the first stunt driver mission, you do not have to jump all the ramps to go through the checkpoints. You are not timed, so you can simply drive through them and turn. If you do this, you do not have to wreck your car when you jump the huge ramps. Near the end of the mission you will have to race Angelina to the finish. You will race faster with a car that is in good shape, therefore making the level easier to complete.

Washington D.C.: Drive on wall

Drive into any entrance to the subway. A fast car is recommended. Get to a good speed and gently drive toward the wall. You will then be on the wall. If you want a good visual of the car, stay in the gray, and not black, part of the wall. There will be some turning required to stay on the gray. If you want to go on the ceiling and come around on the other wall, turn hard toward the wall. You will go around in a hemisphere to the other wall.

Easy checkpoint races

When you are selecting a car, get the Cadillac Escalade. When you start the race, there may be more Escalades. If so, keep restarting the game thorough the "Restart Race" option at the pause screen until there are four ambulances. The ambulances are easy to defeat.

Easy blitz races

Before you start racing in blitz, go into cruise mode. Go to Washington D.C. and enable the "Black and white film effect" trick. When you exit, this effect will still be active, but in color. Go to the blitz races and you will still drive very fast and the time stays the same. You should use a strong car, as damage also accumulates quickly.

Easy hunter game

On Xbox Live!, go into the subway during a game of hunter. Most of the police will not know how to find you as you can cruise through the subway in any level. The subway on the map is always marked with an "M" for metro.

Asp

This car is located is Paris, alongside the Seine river and next to the De La Concorde. The ????? paint can is in the air above the Quai Des Tuileries street along La Seine in Paris. In order to get this vehicle, choose the Koenigsegg CC (the fastest car in the game). Drive through the arches of the Musee Du Louvre and turn right onto Quai Des Tuileries. On the sidewalk, on the left hand side (about one block up) is a ramp. Hit that ramp at full speed to get the paint can. Its stats are

Top Speed: 7
Accereration: 6
Mass: 5
Handling: 5
Durability-3

Black and white film effect

In Paris, find the Moulin Rouge. Hold Right Analog-stick Up to stare at it until the screen changes into black and white.

In Washington D.C. in single player cruise mode, go to the Lincoln Memorial west of the Reflecting Pool. Drive all the way up to the where Lincoln is seated, as close as possible. Hold the Right Analog-stick Up to stare at Lincoln's head until the screen changes into black and white graphics. The game will be faster after doing this. To return to normal do the trick again when still in cruise mode. If you exit out of cruise mode, you must do this trick two times to reverse the effects.

Note: This will change the graphics to black and white with a old film type scratch effect and increase the game's frame rate. If you exit the current game, both effects will still be present in the game menus. When game play is resumed, the black and white effect will be gone, but the increased frame rate will still be in effect, allowing your vehicle to travel much faster than normally possible.

Serpent MK2

This secret car is located in northwest of Washington D.C., near the Mini Cooper's Paint Job at the end of the bridge. You need to use the Koenigsegg CC (fastest car) to drive at fast as possible under the bridge. Note: Start from back in the tunnel. You will fly at the end of the bridge. If you fly high enough, you will touch a labeled "???" paint can high in the air. You will now unlock the Serpent MK2, which is slower but much easier to drive. Its stats are

Top Speed: 8
Acceleration: 7
Mass: 4
Handling: 6
Durability: 4
From Washington Square, drive west on Whitehurst Freeway in a Koenigsegg CC. Take the ramp down, and floor it. After the road turns right, take the ramp up. You will catch air on the hill immediately after the ramp. This may require a few attempts. If you want to see where the paint can is located without all the trouble, drive the same route at a slower speed with the Right Analog-stick Up.

Freightliner Century Class S/T: Faster acceleration

When driving the 18-wheeler hold Y and the truck will accelerate faster. Watch the speedometer to see this effect.

Disappearing ticket dispenser

Take any car that can fit down the subway in Washington D.C. and run it full throttle down the ramp. Note: Do not go fast before you are headed down the escalators or you will jump over the entrance. Once you are accelerating down the escalators, aim straight for one of the little ticket dispensers and hit it straight on. It is very important that you hit it straight on; if you do not, the machine will just fly off to the side. If done correctly, the dispenser will disappear when you hit it.
