FIA

Active aerodynamics: driver-operable wing-flap actuators (front + rear) — Z-mode for cornering downforce, X-mode for straight-line drag reduction; Ground-effect Venturi underfloor retained from 2022-onward regulations; DRS (Drag Reduction System) replaced by the active rear-wing element

Composite chassis must pass FIA crash tests (front impact, side intrusion, rear impact, rollover); Power unit elements limited per season (penalties for exceeding allocation — covered in Sporting Regulations)

1.6 L V6 turbocharged ICE retained; MGU-H removed; MGU-K output tripled; 50/50 ICE-to-electric split (target ~750 kW combined peak power); Energy deployment limits: 4 MJ per lap from MGU-K (up from 2 MJ)

Chassis: single-seat open-cockpit monocoque with halo cockpit protection device; Minimum weight (car + driver, no fuel): 768 kg for 2026 (down from 798 kg); Maximum dimensions: 1900 mm wide (down from 2000 mm), 3400 mm wheelbase (down from 3600 mm), 950 mm overall height

FIA Grade 1 circuits only (homologation required); 23+ circuits on the 2026 calendar; Pit lane speed limit: 80 km/h (race), enforced by car-side limiter; Track-edge kerbs, sausage kerbs, and run-off areas defined per circuit homologation

10 constructor teams × 2 cars = 20 drivers on the 2026 grid; Each car: 1 driver, plus reserve driver entitlement per team; FIA officials enforce Technical Regulations: Technical Delegate, scrutineers, technical commissioners

1.6 L V6 turbocharged ICE retained; MGU-H removed; MGU-K output tripled; 50/50 ICE-to-electric split (target ~750 kW combined peak power); Energy deployment limits: 4 MJ per lap from MGU-K (up from 2 MJ)

The Technical Regulations do not govern race scoring (handled by the Sporting Regulations: 25-18-15-12-10-8-6-4-2-1 for P1–P10, plus 1 bonus point for fastest lap in top 10). Technical scrutineering produces a binary pass/fail outcome — non-compliant cars are excluded from the session results.

Failed scrutineering: car may be excluded from session/race results (e.g., underweight, plank wear excess, fuel sample non-conformance); Power unit allocation exceeded: grid penalties (10 places per additional element); Parc fermé violation: pit-lane start required

Mandatory halo cockpit protection (since 2018) — must pass 116 kN static load test. Carbon-fibre monocoque survival cell with anti-intrusion panels and impact-absorbing nose.
