The final round of the 2026 Hi-Tec Oils Super Series – Season 4 at Calder Park has moved back a week to avoid a date clash with the Supercars Championship.

Entries are officially open, for round one of the Hi-Tec Oils Super Series Season 4 – 2026 and also the inaugural round of the AASA Nationals Series - 2026.

The first ever ‘AASA Pre Season Combine’ will be held at Winton Motor Raceway from February 18-19, a two-day invitational test for Hi-Tec Oils Super Series and AASA Nationals teams and drivers.

Following a successful debut on the Australian Auto-Sport Alliance’s Hi-Tec Oils Super Series roster this season, the APC Enduro Championship has announced its re-commitment to the national program among a raft of exciting changes for 2026.
