Los Angeles police car:

Paris police car:

Tokyo police car:

SLF450X:
Win all the races in Los Angeles, Paris, and Tokyo in arcade mode and complete career mode to unlock the SLF450X. It is the fastest car in the game and can hit 250 mph with no boost. You can only use it in arcade mode.

Zoom on mini-map:
Press Down/Left or Down/Right to zoom in and out of the mini-map at the bottom left corner.

Hint: Quick start:
At the starting line when the countdown begins, hold R to peel out, and then move back and forth to sway the car. This will move you forward slightly, and will give you a better starting position.

Hint: Boost:
When riding the Cohete (motorcycle) and accelerating, briefly hold L to pop a wheelie. This will give you more acceleration/speed.

With any car, after you start to accelerate hold R and it will speed up your car.

After using a slipstream, press Nitrous quickly to go at least 180 mph.

Hint: Los Angeles: Easy motorcycle win:
On the motorcycle level, the best strategy is to knock your opponents off their motorcycles by ramming into them. You can get a good start in the beginning of the race by doing the "burning rubber" strategy and moving to the left into two of the motorcycles and knocking them off.

Hint: 360:
When going at least 130 mph and driving straight, hold Right or Left + Reverse to do a perfect 360.

Hint: Easy turning with motorcycles:
Hold L while driving and use the Analog-stick to make any type of turn. On straightaways, hold Up to duck down to prevent drag.

Hint: Powerslide:
Enable the "Unlimited nitrous" code. Get a motorcycle and begin arcade mode. Find a good straightaway and hold Weight Shift. When you are going fast use the brake and the nitrous at the same time. You will powerslide around faster. It is useful for 180 turns in races.

Hint: Wheelies and side burns:
While playing with any car or motorcycle, hold L and drive above 20 mph. Then, while holding down L, press the Left Analog-stick Left or Left Analog-stick Right with a car and they will turn on their left or right, enabling them to drive sideways. With a motorcycle, press Left Analog-stick Down and you will pop a wheelie. However, you can also press Forward and Forward/Left or Forward/Right to bend down more and be able to do tremendous turns.

Hint: One wheel 180:
While going about 100 mph or more on a motorcycle, pull a medium to high wheelie, press Analog-stick Down and do an endo. Press the Analog-stick Left or Right at the same time to do a front wheel 180 degree turn.

Hint: Barrel roll:
After you unlock the "Driving On Two Wheels" cheat, go to arcade mode and select "Cruise" and a fast car. Then, press the Weight Transfer + Left Analog-stick to get onto two wheels when on a long straight-a-way. Go down the straight-a-way and gain speed. When you reach a turn, use the handbrake to make an extremely sharp turn. If you gained enough speed and turned the correct way, you should have flipped over and landed back on your wheels. In order for this to work, you must take physics into consideration. If you go on your right side wheels, you must turn left to do a barrel roll and vice versa.

Hint: Losing the police:
When side by side with a police car, find a tree or pole ahead that is on the side nearest to the police car. Push the police car into the tree or pole.

Hint: Graffiti:
Look at some of the graffiti on the walls in Los Angeles to find some interesting things. Near a wall by the airport is graffiti that says "Vice City", referring to the fact that Rockstar made both Midnight Club 2 and Grand Theft Auto: Vice City. There is also saw a wall that had "Rockstar" on it.

Hint: Easy wheelies:
Get a motorcycle and do a wheelie for at least three seconds. Then, pull back all the way on the Analog-stick. If done correctly, you will be perfectly balanced.

Hint: Flip the finger:
Choose the motorcycle and go into any mode. Remain idle without moving. After about thirty seconds, the man on the bike will turn around and flip the finger.

Hint: Disturbing portapotty comment:
If you hit a portapotty, a man will say "Leave us alone".

Glitch: Drive totaled car:
Crash your car into the gas pumps. After the explosion, pause game play. When you resume, your car will be totaled, but will still be driveable and also appears to be indestructible. However, if you flip the car over, it will not reset upright.

Glitch: Riderless motorcycle:
When riding a motorcycle, crash into something that will make you fly off the bike. While you are still on the ground, pause the game then resume. Your rider will stay on the ground, but you will be able to drive the bike riderless, as long as you do not crash into anything too hard. You can even double back and push the rider around.

When on the Nousagi or any other bike, when your damage is full and the bike is going to explode, quickly press Start, then select "Continue". The bike will be indestructible, and the rider will be gone.

Glitch: Wrong siren:
You must unlock any police car and at least two of the three cities for this trick. When the siren is activated in a police car in another city, it will sound the same as a police car from that city, and not from where the car was originally from. For example, select the L.A. police car and go to Paris in cruise mode. Turn your sirens on, and it will sound like a Parisian police car instead of the L.A. police car.
