Brown and Wolff weigh in on timing F1 technical changes

McLaren CEO Zak Brown and Mercedes team principal Toto Wolff say Formula 1 must tread carefully on when to roll out technical tweaks under the new 2026 regulations. With compression‑ratio measurement and turbo‑build‑up after the MGU‑H removal under scrutiny, both stress data‑driven, collaborative decisions.

Why it matters:

• Early technical changes shift the competitive balance and strain development budgets.
• Unclear power‑unit rules, especially compression‑ratio testing, affect cost, reliability and fan perception.

The details:

• Compression‑ratio: FIA will vote; a super‑majority is required, and Mercedes is likely the primary target.
• Race‑start turbo build‑up: Without the MGU‑H drivers need extra spin‑up time, prompting procedural tweaks.
• Brown: “We’re still learning in testing; quick changes only if data shows a clear racing benefit.”
• Wolff: “More engineers on the F1 Commission means decisions will be data‑driven, not knee‑jerk, especially at energy‑heavy Melbourne.”
• Post‑summer test: If the vote passes, a dedicated compression‑ratio test could be scheduled after the summer break.

What's next:

• Teams will keep gathering performance data in the opening rounds to inform the Commission.
• The compression‑ratio vote is slated for later in the season, with implementation only after a super‑majority.
• Any mid‑season tweaks will aim to preserve equity while improving race‑start consistency.
