The PSP, Nintendo DS and Game Boy Advance versions of the NFS Carbon game are called Need For Speed Carbon: Own the City. The gameplay is based upon rival street racing clubs and teams. The player can pick specific street racers to be in their crew, who fall into 3 categories: Scouts, who can help find shortcuts throughout a track, Blockers who race alongside the player and target opposing cars during the race to knock them off course and Drafters who create a "slipstream" for the player to follow during a race, which gives a significant speed boost.

Although not included, there was also going to be a type of crew member called the Persuader, but EA had programming issues with it. Also, each crew member will also have a second specialty, again divided into 3 categories: Beginning with Fabricators, who can enable you to modify certain parts of your car and enable "AutoSculpt" (a tool which allows the player to customize the modifications themselves), Mechanics who can give discounts on certain car parts, and Fixers, who can reduce your wanted level after races, have extra cash and get traffic like large Trucks out of your way. Here's a mighty fine list of unlockable cars you can have fun with:
