What happened: Autosport reported that increasing fuel flow could help rescue proposed changes to Formula 1's 2027 engine formula after objections from Ferrari and Audi. The issue follows a fresh deadlock over how far F1 should move away from the 2026 power-unit balance.
Why it matters: The dispute matters because any 2027 change could affect engine design, chassis packaging and cost-cap planning just one season after the new 2026 rules arrived. For Audi, Ferrari and other manufacturers, the central question is whether a fuel-flow tweak can improve drivability without forcing expensive hardware changes.
By the numbers: FIA-backed 2027 proposals previously centered on roughly +50kW of internal-combustion output through higher fuel flow, paired with about -50kW of ERS deployment power. That would shift F1 away from the 2026 target of a more even combustion-electric power split.
What to watch: Watch for the next F1 Commission and FIA World Motor Sport Council steps, where any 2027 rule change would need formal approval. The size of the fuel-flow increase will determine whether this becomes a light adjustment or a deeper redesign fight.
