Mach 1

Mach 1 is the second highest speed class attainable in WipEout HDs Zone Mode. As the name would suggest, the speed is akin to the speed of sound in air. It is the next level up after Subsonic.

This class begins at zone 60, and continues upto and including zone 74. At zone 75, the player will have entered the highest possible speed class, Supersonic.

Trophy Hunters going for the Zone Zeus Trophys, will often find their races coming to an end during this very high speed class.

Interestingly, unlike both of it's adjacent speed classes, Mach 1 does not have a Trophy associated with it.
