The Hypervelocity Autocannon (HVAC) family of weapons is based on the Autocannon. While they have the same damage classes, they're capable of firing much further. However, in order to obtain the increased ballistic range, the hypervelocity ammo is larger, reducing the number of shots per ton of ammo. Like Ultra or Rotary autocannons, Hypervelocity autocannons are unable to make use of special munitions.
