This code is EXTREMLY hard to do and you must time it correctly. Also this code takes a while to get. Type your name as "allunit". Then, go to Hot Pursuit and play as EXPERT mode. Play Duel. Select the track "Dolphin Cove". Select the TITAN car if you typed in the code for it or won it. Once the loading screen appears, wait until the yellow line reaches around the middle. Then, quickly hold down select and press X, Triangle, O, Square, L1 twelve times, and R2 5 times. You must press those buttons in an easy pace. Once the race starts, drive your car all the way to the Dolphin Cove tunnel (2nd tunnel). You are NOT allowed to drive backwards or drive the other way or else the code won't work. Stop at the tunnel and wait for your opponent or a cop to pass by. Once they are near your area, try to ram your opponent or cop. Press and hold X and O exactly when your opponent or cop hits you. If its a cop, you will be fined. If its your opponent, he should be flipping in the air! If he's not doing flips, the code won't work, either. Once you did those, quit the race. Then go to One Player. Next, go to Hot pursuit, EXPERT, Solo. Next, select the track "Kindiak Park". Select the Lamborghini Cop if you earned the car. Once the loading screen appears, Press and hold all the buttons except the directional buttons. If you've done it right, call for backup. Once you call for backup, you will see 8 or 9 which is including you cop flashing dots on the map. Once you see all 8 of those cops, there are 4 Corvette cops and 4 Lamborghini cops. Those units are unit 20, 25, 45, 31, 217, 371, 353, and 316. Good luck and have fun with this code if you got it!
Access super police cars
To gain the extra Police Cars you will have to arrest all ten suspects within the amount of time given at every difficulty level to gain access to the higher performance Police Cars. To get the American/United States Super Police Cars like the Corvette C5 Pursuit car arrest all ten suspects on the Canadian, or USA tracks. A simple tip is to not enter a username by not doing so you will gain extra pursuit time.
Access to all cars
Currently I do not know of any controller button combos or usernames to unlock every single car in the game. You will simply have to get them the old fashioned way and that is win and unlock them on your own. I do have a tip for the harder races that specify no special car be driven. When a race states that the cars used is open chose the BMW M5 since it is a slower good handling car that is difficult to spin out and crash with, especially if you are on the very hard mirrored, backward, or night time tracks that you have never raced on before. Another good tip is if you are not in first place and find yourself on an unfamiliar version of a track you thought you already knew is to follow your opponents the first lap to learn where to slow down and turn at.
All Cars And Tracks
Go to user name and type in wicked, this will allow you to use any car, on any track, but only in Testdrive Mode, the cars include a helicopter, titan car and phantom.

Hot pursuit tips when you are the cops
When you play the role as the Cop immediately at the start of every pursuit call for backup. At the harder difficulty levels you will have to wait a while before any extra backup is available, but if you are having problems pulling over a suspect the extra help will shave valuable time off of your overall time spent on a difficult arrest. Always call for backup!
