The gameplay in the circuit and drag races was similar to what NFSU offered, although the overall experience was different due to the new nitrous system. Unlike the original game, NFSU2's nitrous system will be much more dynamic, allowing you to fill it up by performing all manner of racing feats. The style points system has been beefed up and now awards you with points for near misses and other stylish moves, in addition to powerslides. The points go toward filling up your car's nitrous meter (if you have a nitrous-equipped set of wheels). This new system includes the mighty "nos breaker," which you'll earn by charging your meter twice. If you manage to pull it off, you'll be able to access the über speed burst, which lets you roll faster and longer than your standard nitrous burst allows you to.
