2022 Technical Regulations
2022 was the most substantial technical reset since the turbo-hybrid introduction in 2014. Cars returned to ground-effect aerodynamics — underfloor venturi tunnels generating most of the downforce — with simplified over-car wings designed to trail cleaner wake, improving close following. Pirelli switched from 13-inch to 18-inch low-profile slicks with a new construction. Fuel moved to E10 (10% ethanol). Minimum weight rose sharply due to the 18-inch rims, heavier safety structures and added ballast from the new chassis. Power-unit architecture (1.6-litre V6 turbo-hybrid with MGU-K + MGU-H) carried over from 2021; PU specification was frozen at the start of 2022.
Ground effect — underfloor venturi
The defining change: the floor houses two venturi tunnels running front-to-rear, accelerating air under the car and generating the bulk of downforce via a low-pressure zone. The aim was to reduce the proportion of downforce produced by complex over-body surfaces, which had become sensitive to leading-car turbulence. Computational-fluid-dynamics studies commissioned by the FIA suggested the new cars would lose less downforce following another car within one second than the 2021 generation.
Key changes
- Return to ground-effect underfloor aerodynamics (first time since the 1980s).
- Simplified front and rear wings designed to trail cleaner wake.
18-inch Pirelli slicks
Pirelli moved from 13-inch to 18-inch low-profile slicks with a new tyre construction. Wheel rims were standardised supplier parts. Wheel covers were reintroduced to control aerodynamic management around the wheels and reduce disturbance to the following car.
Power unit — architecture retained, development frozen
The 1.6-litre V6 turbo-hybrid (ICE + MGU-K + MGU-H + ES + CE) architecture carried over from 2021. The FIA introduced a PU development freeze starting in 2022 and lasting through 2025, allowing reliability-only upgrades. E10 fuel replaced the prior E5 specification to align with road-car and sustainability policy.
Key changes
- PU development freeze 2022-2025.
- E10 fuel (10% ethanol) introduced.
Minimum weight & safety structures
Minimum weight rose vs 2021 as a result of the 18-inch wheels, strengthened survival-cell crash structures, mandatory additional side-intrusion panels and the weight of the new floor. Halo remained mandatory. Several cockpit and anti-intrusion crash-test loads were increased vs the outgoing regulations.
Exact crash-test load numbers and the precise minimum-weight figure were not inlined — verify against the published 2022 Technical Regulations.
Standardised & prescribed parts
To curb R&D spend and simplify supply chains, 2022 introduced a larger catalogue of standardised and prescribed parts — wheel rims, certain fuel-system components and elements of the steering-wheel/electronics chain among them. Standardised parts come from a designated supplier; prescribed parts can be made in-house but must meet a fixed geometry.
