The FIA published a packet of official documents ahead of the 2026 Austrian Grand Prix that includes the entry lists, the power unit elements used logs, curfew rules, and a Doc 12 steward-substitution notice. The power unit elements log records each team’s declared PU components for the weekend, while the entry lists confirm the drivers and cars entered for the Red Bull Ring round. The Doc 12 filing shows at least one steward substitution for the event week. Separately, the FIA has declared the Austrian GP a heat-hazard race and authorized a weight break to allow teams to add cooling equipment such as a pump and fluid circuit for driver cooling. An FIA technical document circulated to teams also lists the upgrades each squad has introduced, with Red Bull’s extensive home-race upgrade package explicitly noted in that material.
