Nitrous

Nitrous (Also known as NOS) is a powerup which will give the player a quick burst of speed to the player's vehicle. The effect of the Nitrous powerup differs from car to car, however, the effect can be improved with the help of 3 different Skill Mods.

Trivia
Cars with a strong Nitrous output have gained the reputation as Cosmic Nitrous cars within the Need for Speed: World community.
