Underground Racing League (URL) is a player versus player game mode along an enclosed race course with a set number of laps. The available selection of URL courses depends on the player's current stage within the career mode. Completing an event will unlock it for selection within Quick Race. The starting grid of all URL races consist of five rival racers and the player. All participants have a chance to earn a 'Head Start' during the race countdown by hitting the optimal rev range upon the countdown finishing.
