FIA Regulations
Technical and sporting regulations of Formula 1, summarised in plain language. Each summary cites the regulation set it's derived from and links to the official FIA PDF when available.
2026season
2026 Technical Regulations
2026 marks the largest technical reset since 2014. The power unit, chassis, aerodynamic philosophy and fuel are all re-architected simultaneously. The engine retains the 1.6-litre V6 turbo-hybrid but shifts to a near 50/50 split between combustion and electrical output, drops the MGU-H, and must run on fully sustainable fuel. Cars are smaller, lighter and narrower, and introduce active aerodynamics that a driver toggles between a low-drag straight-line mode and a high-downforce cornering mode.
2026 Sporting Regulations
The sporting rules evolve more gradually than the technical reset. The core race weekend format (FP1 · FP2 · FP3 · Qualifying · Race, or FP1 · Sprint Qualifying · Sprint · Qualifying · Race on sprint weekends) carries over from 2025. What's new in 2026 is a larger grid (22 cars, Cadillac joining Audi), revised power-unit component allocations to match the new PU life cycle, and refreshed tyre-allocation mechanics to handle the post-DRS reality. Super licence points, steward protocols and dispute windows remain effectively unchanged.
2025season
2025 Technical Regulations
2025 was the closing chapter of the ground-effect era introduced in 2022. The core chassis-aero-PU architecture carried across unchanged: 1.6-litre V6 turbo-hybrids with MGU-K + MGU-H, ground-effect venturi floors generating the majority of downforce, and 18-inch low-profile Pirelli slicks. The year's changes were incremental — front-wing flexibility clarifications, floor-edge tweaks to curb porpoising tendencies and minor cockpit ergonomic updates. No foundational rewrite because teams and the FIA were both focused on 2026.
2025 Sporting Regulations
2025's sporting rulebook evolved from 2024 with two headline items: the retirement of the fastest-lap bonus point (effective from the end of 2024 season), and the introduction of formalised racing guidelines as an appendix, codifying who owns the apex in overtaking situations. The weekend format (standard and sprint), grid size (20 cars), cost cap structure, and super-licence system all carried over unchanged.
2024season
2024 Technical Regulations
2024 continued the ground-effect platform introduced in 2022, with the same 1.6-litre V6 turbo-hybrid power units (ICE + MGU-K + MGU-H) and 18-inch Pirelli slicks carried over from 2023. Headline tweaks were clarifications around front-wing and rear-wing flexibility — policed via in-season Technical Directives rather than headline rule changes — plus minor floor-edge geometry adjustments. The chassis weight, wheelbase limits and bodywork template stayed constant, preserving the period of development stability teams had lobbied for ahead of the 2026 reset.
2024 Sporting Regulations
2024 ran with the calendar format consolidated in 2023 — up to 24 grands prix, six sprint weekends, a three-free-practice standard weekend and the revised sprint weekend format. Entries stayed at 10 constructors × 2 cars = 20 drivers. Housekeeping items dominated: small clarifications to parc-fermé, formation-lap procedures and the sporting code around penalty points. The championship framework (driver + constructor titles, 25-18-15-... points, sprint 8-7-6-...-1) was unchanged.
2023season
2023 Technical Regulations
2023 was the first set of targeted fixes to the 2022 ground-effect platform. The most widely reported change was a raised floor-edge height and tweaks to the diffuser throat aimed at reducing porpoising — the aero oscillation that had bitten teams in 2022. The minimum weight was trimmed slightly after teams argued 2022's figure was too punishing. Power-unit architecture was unchanged: 1.6-litre V6 turbo-hybrid (ICE + MGU-K + MGU-H + ES + CE). Pirelli continued supplying 18-inch low-profile slicks.
2023 Sporting Regulations
2023 was the year the sprint weekend was redesigned. A dedicated Sprint Shootout qualifying session was introduced on Saturday morning to set the sprint grid, decoupling the Saturday sprint from Sunday's grid — which remained set by Friday's main qualifying. Six sprint weekends were scheduled. The calendar planning framework allowed up to 24 rounds. The two-compound race rule, 25-point GP scoring and 8-7-6-... sprint scoring were unchanged from 2022.
2022season
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.
2022 Sporting Regulations
2022 was the first full season of the new ground-effect technical platform and the second year of the financial regulations (cost cap). The Sporting Regulations ran with three sprint weekends (pre-redesign), the two-compound race rule, and the 25-18-15-... points scale. Ten constructors × 2 cars = 20 drivers. The headline sporting item was the lowered cost-cap ceiling on its declining schedule from 2021's debut figure.
2021season
2021 Technical Regulations
2021 was a bridging year: the big rule reset originally planned for 2021 was pushed to 2022 because of the COVID-19 pandemic. Teams carried over the 2020 chassis under a token system (a fixed budget of development changes per team) and the PU architecture was also largely frozen. The notable technical change was a targeted reduction in rear-end downforce — new floor cut-outs and brake-duct restrictions — introduced after the high-speed tyre failures of the 2020 season. Pirelli also modified tyre construction.
2021 Sporting Regulations
2021 was the debut year of the constructors' cost cap under the new Financial Regulations framework, and the year the sprint-race format was introduced as a trial at three events. The GP points scale (25-18-15-...) and the 1-point bonus for fastest lap (when set by a top-10 finisher) were carried over from 2019/2020. Sprint points at 3-2-1 for P1-P3 were introduced at the trial events, along with the sprint's role as the official setter of the Sunday grand prix grid.
2020season
2020 Technical Regulations
2020 was the last year of the 2017-era aero envelope. Cars still ran 13-inch Pirelli slicks, over-car wing-dominated aero and the same 1.6-litre V6 turbo-hybrid architecture introduced in 2014. Mid-season, due to COVID-19, the FIA and teams agreed to postpone the originally-planned 2021 rule reset to 2022, and chassis homologation was extended — 2021 cars would be carryovers on a token-limited development basis.
2020 Sporting Regulations
2020 was defined by COVID-19 disruption. The season, originally planned to open in Melbourne and extend to 22 rounds, restarted in July at the Red Bull Ring behind closed doors and ran 17 grands prix, many as double-headers at the same circuit (e.g. Spielberg I+II, Silverstone I+II). The regulatory text was amended repeatedly mid-season through FIA communications covering paddock access, testing, post-season factory shutdown and force-majeure provisions. The baseline points system (25-18-15-...), the two-compound rule and the 1-point fastest-lap bonus carried over from 2019.
2019season
2019 Technical Regulations
2019 brought a targeted aero change aimed at making overtaking easier as a bridge towards the larger reset then planned for 2021. Front wings became wider and simpler (fewer stacked elements, no outwash-y-250 endplates), rear wings became taller and wider (larger DRS flap slot opening), and brake-duct winglet furniture was curtailed. 1.6-litre V6 turbo-hybrid PU architecture was unchanged. Pirelli allocation structure was simplified (five compounds named 'C1'-'C5' instead of the seven-colour system prior).
2019 Sporting Regulations
2019 brought two crowd-pleasing changes: the return of the bonus point for fastest lap (set by a top-10 finisher), and the simplification of Pirelli's compound naming from the seven-name system (Superhard to Hypersoft) to five numbered compounds (C1 hardest to C5 softest) applied race-by-race. Twenty drivers across ten teams, standard FP1/FP2/FP3/Qualifying/Race weekend, two-compound rule in the dry.
2018season
2018 Technical Regulations
2018 is remembered as the year F1 made cockpit head-protection mandatory: the Halo became required equipment on every car. The regulations also outlawed the shark-fin engine cover and the T-wing decorations that had sprouted in 2017. PU architecture (1.6-litre V6 turbo-hybrid) was unchanged, and the Pirelli compound lineup (Superhard to Hypersoft) gained the Hypersoft as the new softest option.
2018 Sporting Regulations
2018 was a housekeeping year on the sporting side: the calendar ran 21 events, 10 teams × 2 drivers = 20 cars, and the points system carried over from 2017 (25-18-15-...). Halo introduction on the technical side prompted procedural updates — primarily around recovery and extraction scenarios. The grid-penalty convention around exceeding PU component allocation remained structurally the same with small clarifications.
Frequently asked questions
01What are the big changes coming in the 2026 Formula 1 regulations?+
The 2026 season introduces a full platform reset: a new power unit with roughly 50/50 split between the internal combustion engine and the electric motor (no more MGU-H), 100% sustainable fuel, a lighter and narrower chassis, active aerodynamics replacing DRS, and an updated safety package. The grid also expands to 22 cars with Cadillac's entry as the 11th team.
02Is DRS banned in 2026?+
DRS as a driver-activated flap is retired under the 2026 regulations. It is replaced by a broader active-aerodynamics system — both front and rear wings change shape across low-drag and high-downforce modes, managed by the car on defined sections of the lap.
03Do the cars still use hybrid power units in 2026?+
Yes. The 1.6-litre V6 turbo architecture continues, but the hybrid split is rebalanced: the MGU-H is removed, the MGU-K generates much more electrical power, and the energy store is larger. Fuel is fully sustainable (drop-in synthetic or advanced biofuel), not the E10 blend used in 2022–2025.
04How many sprint weekends are there in 2026?+
The sporting regulations allow six sprint weekends, matching the 2023–2025 format. The Saturday Sprint Shootout + Sprint layout carries over, with the Sunday grand prix grid still set by Friday's main qualifying.
05What is the 2026 grid size and which teams are entered?+
Eleven constructors × two cars = 22 drivers on the grid in 2026. Cadillac joins the existing ten teams as the 11th entry. Driver pairings and contracts are not part of the Technical/Sporting Regulations; check the 2026 season hub for the latest grid.
