Overview

• Deputy chief engineer Jonathan Heal says 2026 could be a “lottery” due to major power‑unit unknowns and the risk of a 2014‑style imbalance.
• James Vowles argues power‑unit performance is unlikely to produce gaps comparable to 2014, shifting focus to chassis differences.
• Vowles estimates chassis concepts under the new rules could account for roughly half a second per lap in variation.
• Stricter 2026 safety standards mean teams cannot carry over 2025 chassis components, forcing clean‑sheet designs.
• Customer outfits face added dependency as packaging and timelines are dictated by engine suppliers, with Haas citing reliance on Ferrari definitions.
