Modes

The game provides players with a selection of game modes, which include a combination of races and police chases. In Career mode, achieving goals by winning races and performing a number of actions, dubbed "Milestones", during police pursuits, as well as a minimum Bounty (see #Pursuit system for details on Milestones and Bounties) are needed to advance in the storyline and race against any of the mode's 15 Blacklist racers. In the Xbox 360 version, the player is awarded with Achievement Points each time a Blacklist opponent is defeated. Career mode introduces a new feature - the ability to win a Blacklist opponent's car ("pink slip"), bonus functions (e.g. the ability to "Get Out of Jail Free") or car parts and decors ("backroom parts"), after defeating the opponent in question. These come in the form of six markers - the rival's pink slip (which is concealed as a bonus marker), two bonus function markers, and three custom backroom parts markers of which there is a part, visual, and performance marker (called a "Junkman Marker") that the player can select - of which the player can choose only two. New cars and parts are also unlocked as the player progresses through Career mode by beating Blacklist racers.

In addition to the Quick Race and Career modes, there is also a "Challenge" mode comprised of 68 progressively difficult challenges (69 in the Black Edition) where players are required to successfully complete Tollbooth races and pursuit challenges, such as disabling a number of police cars. The pre-tuned cars used in each Challenge is fixed, ranging from mostly Career cars with poor handling to traffic vehicles such as a cement truck or police cars. Additional bonus cars may be unlocked as the player progresses through Challenge mode.

In terms of actual variations of races, Most Wanted inherits several racing modes prevalent in its Underground predecessors. The game's four existing modes: Circuit races, point-to-point Sprint races, Lap Knockout races and Drag races, remain largely unchanged since the first iteration of Underground, while Drifting, Street X, Underground Racing League tournaments and Outrun racing are foregone. Meanwhile, Most Wanted see the introduction of two new racing variations, which places emphasis on speed. The first mode is known as "Tollbooth," where a player races alone to designated checkpoints (toll booths) along a point-to-point route before time runs out (similar to Time Attack modes in arcade-style racing games); the more time a player has as they reach a toll booth, the more time they have to arrive at the next one. The second mode, dubbed "Speedtrap," sees racers competing with each other to get the highest accumulated speed record at multiple traffic cameras. At a speed trap/traffic camera, players accelerate their car to aim for the highest possible speed. Accumulated speed is reduced over a period of time after an opponent crosses the finish line first.
