Formula 1 is preparing to overhaul its power unit rules again, with a preliminary agreement among the FIA, FOM, teams, and engine manufacturers to replace the current 1.6L V6 hybrid turbos with 3.0L V8 turbos and a much smaller hybrid system. The change could be introduced as early as 2030, a year ahead of the originally planned 2031 cycle.
The move responds to problems with the 2026 regulations, which aimed for a near 50:50 split between combustion and electric power. The small battery can only deliver full electric power for about 11-12 seconds per lap, and complex energy management algorithms have caused sudden torque spikes and crashes. The new plan would cut electric assist to roughly 134 hp and make power units at least 110 lbs lighter.
For automakers, the shift represents a pragmatic retreat from aggressive electrification. F1 had attracted Audi, Cadillac, and Ford with its hybrid-heavy formula, but the new direction prioritizes reliability, cost control, and road relevance through turbocharging rather than pure electric performance. The lighter, simpler power units could also help reverse the trend of ever-heavier cars, a long-standing complaint among teams and fans.
