 On 14 December 2017, it was announced by the Australian HPV Super Series and the Victorian HPV Grand Prix Series that National Vehicle Specifications had been adopted for the 2018 season onward, subjecting both series to common vehicle specifications and making it easier for teams to compete across both series without needing to change their vehicle set-ups; in previous years, both series had their own specification guidelines to comply with.The four categories are divided under two classifications of "School Categories" and "Community Categories".Introduced in 2006, all school and community categories have further sub-categories for All Female teams.
