Speed Classes

In WipEout HD there are a number of different 'Speed Classes' which are essentially a measurement of difficulty for the player. Later on in Campaign events, higher speed classes will become more normal. Conversely, towards the start of a Campaign, the slowest speed classes will be the norm.

Zone Mode lets the player experience a larger number of speed classes, by introducing 'sub-' and 'super-' classes just before the hitting of the next class up. Zone mode also allows the most skilled players the opportunity to experience some incredibly fast speed classes as they hit the very high zones.

After Supersonic, the player will still notice an increase of speed per zone, but will not attain a new Speed Class and remain therefore in Supersonic.

Here is a list of all the speed zones present in WipEout HD, including the sub-classes only found in Zone Mode:
