Why change now? The FIA’s goals
The 2026 package ties road relevance, sustainability and raceability together: more electric power, cleaner fuel, and aero/energy tools to help cars follow and pass. The governing body highlights lighter, more agile cars, active aero, and the new overtake boost to improve the show.

At‑a‑Glance (60‑sec summary)
- Power unit (PU): ~50/50 ICE–electric split, MGU‑H removed, 100% sustainable fuel. Six registered PU makers for 2026–2030: Red Bull‑Ford, Ferrari, Mercedes, Honda, Audi, Alpine/Renault.
- Active aero: Two modes—X‑mode (low drag for straights) and Z‑mode (high downforce for corners).
- Manual Override (MO): On‑demand electrical boost for overtakes; functionally replaces DRS.
- Chassis targets: Smaller and lighter cars (approx. 30 kg lighter, narrower and shorter than 2022‑25 spec).
- Tyres: Width cut by −25 mm front / −30 mm rear; diameter trimmed to ~705–710 mm; 18‑inch rims retained.
- Safety: Stronger structures, increased side‑intrusion, brighter rear lights, new lateral ERS‑status lights.
- 2026 testing & calendar: Three official tests (Barcelona Jan 26–30; Bahrain Feb 11–13 and Feb 18–20); season opens Australia, Mar 6–8; Azerbaijan moved to Sat Sep 26.
Power Units: from ~80/20 to ~50/50
Headline changes
- Even split between ICE and electrical contribution (target), with ~350 kW from ERS and ~400 kW from the ICE often cited in briefings; MGU‑H deleted; 100% sustainable fuel mandated.
- Six registered PU suppliers for 2026–2030: Alpine (Renault), Audi, Ferrari, Honda, Mercedes, and Red Bull‑Ford.
What this does on track
More battery contribution means energy management becomes race‑deciding—harvesting, deployment windows, and the interaction with Manual Override (below). The ICE still matters for drivability and fuel efficiency, but teams will chase battery recovery and cooling gains to hit stint‑long targets. (Inference from FIA/F1 outlines.)
Manual Override vs DRS
Manual Override (MO) gives the chasing driver a short burst of extra electrical power when within a proximity threshold (~1s) to the car ahead—replacing DRS from 2026. That makes overtakes less wing‑position dependent and more about energy tactics.
| Feature | DRS (2011–2025) | Manual Override (2026→) |
|---|---|---|
| Activation | Within 1s at DRS detection; flap opens in DRS zones | Within threshold; temporary ERS boost available |
| What changes on car | Rear wing slot opens to cut drag | Electrical power deployment; aero managed by X/Z‑mode |
| Driver skill lever | Exit speed + timing DRS zone | Energy timing + battery state + race craft |
| Goal | Reduce drag to pass | Use electrical shove while aero remains optimized for corner/straight |

Active Aerodynamics: X‑mode and Z‑mode
- X‑mode: Low‑drag configuration for the straights to keep speeds competitive with higher electrical share.
- Z‑mode: High‑downforce configuration for corners to keep grip.
FIA/F1 material describes moveable front and rear wings coordinated with the car state to improve following and reduce wake sensitivity.
Chassis: smaller, lighter, nimbler
Compared to 2022‑2025 cars, the target is ~30 kg lighter, narrower and shorter overall—addressing the bloat that crept in over recent cycles. This helps low‑speed agility and reduces energy demand.
(Regulatory PDFs continue to be iterated; final build specs live in the FIA’s Section C updates.)
Tyres: narrower, slightly smaller diameter—18" rims stay
- Width trimmed by 25 mm (front) and 30 mm (rear) vs current; external diameter reduced to ~705–710 mm (current slicks ~720 mm).
- 18‑inch wheel diameter retained.
Pirelli’s 2026 prototypes already ran in Barcelona under these targets; development focuses on maintaining grip and controlling overheating with less section width.
Safety updates you’ll notice (and some you won’t)
- Stronger side‑intrusion protection (around cockpit and fuel cell).
- Two‑stage front impact structure to keep protection after initial hits.
- Brighter rear wing endplate lights and new lateral safety lights to indicate ERS status on a stopped car.
These are directly referenced in 2026 briefings and tech rundowns.
Sporting & Cost Controls: CFD/Wind‑Tunnel & the development clock
Teams were barred from aero dev on 2026 cars until Jan 1/2, 2025, via ATR/CFD restrictions—limiting early advantages and compressing timelines. Expect the usual wind‑tunnel/CFD allocation ladder (performance‑based) to shape mid‑season gains.
Implication: 2026 should deliver a bigger initial spread than year two, with the development race closing gaps as allocations bite.
Entrants & Engine Suppliers: the 2026 edition
- Audi/Sauber: Sauber transitions into the Audi works team for 2026; Audi completed a full takeover and has been ramping up infrastructure and leadership for launch.
- Cadillac (GM): In March 2025, FIA and F1 approved Cadillac as the 11th team for 2026 after the original Andretti‑Cadillac bid was rejected for 2025/26. Early phase operation to use a customer PU before GM’s own unit is ready later in the decade, per reporting. (Watch this space for any spec changes.)
- Six registered PU suppliers (2026–2030): Alpine (Renault), Audi, Ferrari, Honda, Mercedes, Red Bull‑Ford.
