October 28, 2026

• RUTH BUSCOMBE, engineer, strategist and TV broadcaster, told analysts in Austin the 2026 F1 rules are the sport’s most sweeping overhaul since 2014.
• Speaking at a pre-race HPE event at COTA, BUSCOMBE highlighted the 50/50 ICE-electrical power split, 100% sustainable fuel mandate, and revised downforce philosophy as headline changes.
• The event formed part of Mercedes-AMG’s push to explain how HPE high-performance computing cuts pre-race simulation time from three days to one under the tighter cost-cap era.
• BUSCOMBE’s presence underlines the growing profile of women in senior F1 technical and communications roles, adding authoritative voice to a landmark regulation cycle.
