Career mode incorporates a monetary reward system that allows a player to purchase vehicles and performance upgrades while earning cash by racing in a chronological set of tournaments. It is also the last game in the Need for Speed series for PC to feature a split-screen two player mode. Moroever, this version presents damage models. These are vehicles which have been involved in accidents featured visibly crushed car bodies and suffered from performance penalties. After a race in Career mode, the player can purchase repairs.
