Section 1: Introduction

The FIA Formula 1 Technical Regulations define the design, construction, and homologation rules for every F1 car. Unlike the Sporting Regulations (which govern race procedure, qualifying, penalties on track), the Technical Regulations govern what teams can build: chassis dimensions, aerodynamic surfaces, power unit architecture, fuel, tyres, electronics, and safety structures. The 2026 Technical Regulations are a generational reset — the largest single-season rule change since 2014. Key shifts: new power unit (50/50 electric/internal-combustion split, no MGU-H), 100% sustainable advanced fuel, narrower and lighter cars, and active aerodynamics. See the sibling FIA Sporting Regulations entry for race-day procedure.

Section 2: Equipment

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
Power unit: 1.6 L V6 turbo + Energy Recovery System; ~350 kW from ICE + ~350 kW from electric (vs. ~120 kW pre-2026)
Fuel: 100% sustainable advanced bio/synthetic — mandated for 2026
Tyres: Pirelli; reduced front width (370 mm → 355 mm), narrower rears for 2026
Aerodynamics: ground-effect underfloor retained; new active front + rear wings with driver-actuated "Z-mode" (high downforce) and "X-mode" (low drag)

Section 3: Playing Area

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
Garage / pit equipment standards: fuel rig flow rate (capped at 2.4 L/s under sporting regs), wheel-gun specs

Section 4: Players & Officials

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
Each team submits design drawings + finished-car homologation pre-season; cars are inspected pre-race for technical conformance

Section 5: Rules of Play

Power Unit Architecture (2026)

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)
Fuel flow rate cap: 3000 MJ/h (energy-based, replacing 100 kg/h mass-based cap)

Aerodynamics

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

Materials & Construction

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)

Section 6: Scoring

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.

Section 7: Violations & Penalties

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
Cost cap breach: financial penalty + sporting penalty (e.g., reduced wind tunnel hours)
Design protest: FIA Technical Department issues binding Technical Directives during the season; teams may protest competitor cars after a race

Section 8: Safety Considerations

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. HANS device + fireproof Nomex suit + full-face helmet (FIA 8860-2018 or 8859-2015) required. ECU and accident data recorder (ADR) capture impact telemetry. New for 2026: revised side intrusion panel standards reflecting increased focus on T-bone scenarios. FIA Medical Car follows the grid for the first lap of every race. Marshals, extrication teams, and on-site medical centre required at every Grade 1 circuit.
