FIA considers refueling return and customer engine overhaul

The FIA is exploring major changes for F1's next era, with president Mohammed Ben Sulayem confirming that refueling and an independent customer engine are under consideration for post-2030 regulations. The proposals signal a shift from turbo-hybrid power toward lighter, simpler V8 cars using sustainable fuels.

Why it matters:

A refueling comeback would alter race strategy for the first time since 2009, while an FIA-controlled independent engine would address concerns about manufacturer leverage over customer teams. Both moves could reshape the competitive and political balance of the grid.

The details:

• Refueling study: The FIA president confirmed the governing body is evaluating refueling for a proposed V8 era around 2031. Smaller fuel tanks with pit stops would support targets to cut car weight by up to 100kg.
• Sustainable approach: Any return would use sustainable fuel with potentially increased electrification beyond today's 10%, balancing environmental goals with lighter machinery.
• Customer engine overhaul: The FIA is weighing an independent, FIA-approved power unit to replace the current customer model. Ben Sulayem said this would prevent factory teams from applying political pressure through engine supply terms.
• Current landscape: Mercedes powers McLaren, Williams and Alpine, while Ferrari supplies Haas and Cadillac. Red Bull Ford Powertrains serves both Red Bull-owned teams, highlighting today's concentrated dependencies.

Between the lines:

These early proposals reveal a pivot toward lower costs and less manufacturer control. But convincing existing suppliers to accept an independent engine program—and resolving refueling safety—will trigger fierce debate before any 2031 framework is finalized.
