One-on-One is a single player event. Players race one-on-one with the Rival of each league. Players must compete in other races to unlock lights and fans whilst meeting the demands of the league's Rival to unlock the one-on-one event.
Winning this event requires skill and strategy as Rivals are tricky competitors and are far more aggressive than normal racers. In order to win the player must either finish ahead of or wreck their Rival's vehicle. Winning the One-on-One event unlocks the Rival's car and Mod for use in the Single Player Career.
