Charles Leclerc Warns of 'Trickiest Point' in F1 Rule Change Debate

Charles Leclerc has voiced concern over the 'trickiest point' in F1's proposed power unit rule change: ensuring fairness across all teams. The shift from the current 50/50 split between internal combustion and electrification to a 60/40 split in 2027 — a change Max Verstappen has called the minimum to keep him in the sport — has hit resistance from Ferrari, Audi, and Cadillac.

Why it matters:

The rule change would come just one year after F1's biggest regulatory overhaul in history. Teams have spent years developing their 2026 power units under the 50/50 framework. An abrupt adjustment could unfairly penalize those who optimized for the original balance, potentially reshaping the competitive order.

The details:

• The current regulations feature a 50/50 split; the proposed change would tilt toward electrification at 60/40 from 2027.
• The paddock appeared unanimous in Miami but division emerged in Canada, with Ferrari, Audi and Cadillac reportedly blocking the change.
• Leclerc stressed the complexity: 'Every team has very different designs and very different ways they approach these rules. Finding something that makes sense for everybody and is fair is a lot more complex than we initially thought.'
• He acknowledged that steps in the right direction have been taken, but cautioned that more work is needed on specifics.

What's next:

The F1 commission continues negotiations. Leclerc expects a difficult path to consensus, but noted that 'everybody is working towards it.' The outcome will determine not only the 2027 power unit formula but also the future involvement of key teams and drivers.
