F1 teams back shorter races to unlock 2027 power unit changes

A proposal to shorten select races and limit laps to the grid has won team support as part of a package to allow Formula 1's power units to move toward a 60/40 combustion-to-electric split for 2027. The agreement in principle came after the Miami Grand Prix, but two major obstacles—extra costs and the fate of the ADUO catch-up mechanism—still threaten the timeline.

Why it matters:

• The 60/40 shift would increase fuel flow rates, requiring bigger tanks. Teams planning to carry over 2026 chassis faced a capacity issue at thirsty venues.
• Shorter races (by one or two laps) and a single formation lap remove the need for expensive new chassis builds, preserving cost cap limits.
• Without a deal, the grid risks stalling on a balanced power unit formula that could affect competition and sustainability goals.

The details:

• Race reduction: Only affected races would be shortened, and only where absolutely necessary. Racing Bulls team boss Alan Permane confirmed the concept has “agreement at team principal level.”
• Cost hurdle: Redesigning hardware for 2027 is estimated to cost an extra $10 million. Audi is reportedly resisting any added spending now.
• ADUO dispute: Ferrari sees the Additional Design and Upgrade Opportunities (ADUO) as its best chance to catch Mercedes. Opening engine homologation for 2027 would scrap ADUO, making Ferrari oppose the 60/40 plan unless a compromise is found.

What's next:

• Further talks at the Canadian Grand Prix aim to bridge divisions. A possible middle ground: adjust fuel flow enough to boost qualifying performance without major engine redesign.
• Red Bull team boss Laurent Mekies noted the pressure is on the power unit side: “There is some tension from a timing perspective. We are all trying to converge as quickly as we can.”
