Formula 1 is weighing major changes to its future power units, with leaders pushing for simpler designs that could limit the influence of carmakers. The shift comes as the series enjoys record financial growth and greater independence.
Formula 1 CEO Stefano Domenicali has called for stakeholders to agree on the next generation of power unit regulations as early as this year. He emphasized the need to act quickly due to long lead times, while respecting investments from manufacturers like Audi and Honda. Domenicali backs lighter, simpler engines centered on sustainable fuel and strong internal combustion.

The FIA has approved several last-minute adjustments to the Formula 1 regulations ahead of the 2026 season-opening Australian Grand Prix in Melbourne. Key changes include closing an engine compression ratio loophole and tweaking the qualifying format, though some issues like energy management remain unresolved. These updates aim to address technical controversies and ensure fair competition from the start.
Audi has joined calls for the FIA to investigate potential loopholes in the 2026 Formula 1 engine regulations concerning compression ratios. Manufacturers like Mercedes and Red Bull are accused of using materials that allow higher ratios at operating temperatures, potentially gaining up to 15bhp. A key meeting is set for January 22 to discuss dynamic measurement methods.

Ben Hodgkinson, director of Red Bull Ford Powertrains, predicts that while the internal combustion engine may drive differences in the new 2026 power units, aerodynamics pose a greater risk of dominance similar to Mercedes in 2014. Speaking ahead of Formula 1's regulatory overhaul, he emphasized the similarities in engine designs and the accessibility for newcomers like Audi. The FIA also anticipates engine performance to shape the grid order, though convergence is expected over time.
