Overview

• FIA simulations project an initial 1.0–2.5 second per-lap deficit for 2026 cars, with regulators insisting lap-time comparisons will fade as development closes the gap.
• Traditional DRS will be removed and replaced by active X and Z aerodynamic modes plus a push-to-pass‑style Manual Override designed specifically to aid overtaking.
• The FIA says the Manual Override’s strength will vary by circuit to avoid passes that are either too easy on straights or too hard into braking zones.
• Nikolas Tombazis cautions that the models lack full team data and that some cars that miss the initial design window could run slower than simulations indicate.
• Drivers testing early simulator builds report a different feel and raise concerns over enjoyment and energy management, even as Mercedes suggests top speeds could approach 400 km/h under full power.
