Unlike Need for Speed: Underground, nitrous is no longer limited and can be regained through the Racebreaker feature. It will restore a certain amount of used nitrous capacity upon the player performing driving stunts or giving themselves an competitive edge in a race. The player can fill up to two nitrous bars, with the second bar being highlighted by a brighter colour.
Several Racebreaker actions will be multiplied the more often the player is able to repeat them. However, the multiplier will be reset if the player fails to meet an action's prerequisite by crashing with a traffic car for instance.

The following actions do not have set amount of points but increase over time the longer the player is able to perform an action, although the player will lose points for hitting a traffic vehicle;
- Burnout - Spin the rear wheels and lay a patch of rubber
- Draft - Stay behind the slipstream of a racer
- Hangtime - Perform a big jump
- Hydros - Perform a series of hydraulics jumps
- Powerslide - Perform a drift
- Reverse - Drive in reverse
- Traffic Hit - Hit a traffic vehicle
Nitrous Purge is a Car Specialty that sprays nitrous out of valves under the hood when activated. It can also be sprayed out of the front wheel wells if upgraded.
- Exiting a Shop refills one nitrous bar.
- The use of a filled Nitrous bar is more effective than several smaller doses.
