The 2026 F1 Regulations Explained: What Changed and Why It Matters

Everything Changed on March 8, 2026

The first lap of the [2026 Australian Grand Prix](/races) looked nothing like any Formula 1 race before it. Wings moving between corners. No DRS flap snapping open on the main straight. Drivers manually choosing when to fire their electrical boost. The 2026 regulations are the most radical technical overhaul since the ground-effect return in 2022 — and unlike 2022, the racing has actually improved.

Here is what changed, why it changed, and what it means for the competitive order.

Active Aerodynamics — The Wings Move

This replaces DRS entirely. Instead of a crude flap that opens on designated straights when you are within one second of the car ahead, the entire aerodynamic package adapts continuously. The result is cars that are faster through corners (more downforce available) and faster on straights (less drag) than the 2025 cars, despite having less powerful engines.

The visual effect is striking on TV — you can see the rear wing elements tilting as cars brake for corners and flattening as they accelerate away. It looks like the car is breathing.

Overtake Mode — Replacing DRS

DRS is gone. In its place is Overtake Mode — a system that gives the chasing driver additional electrical power on designated straights when they are within one second of the car ahead. The defending driver does not get this boost.

The key difference from DRS: Overtake Mode affects acceleration, not just top speed. A DRS pass often happened by the car ahead simply being unable to defend on the straight. Overtake Mode provides a speed delta but the defending driver can still use their own energy management strategically. The result is more genuine racing and fewer "highway passes."

Manual Override Mode (MOM) — The Strategic Layer

Every 2026 car has a new energy management system that gives drivers direct control over when to deploy electrical power. This is called Manual Override Mode, or MOM.

In previous hybrid seasons (2014-2025), energy deployment was largely automated — the car decided when to use the battery and when to harvest. MOM puts that choice in the driver's hands. A driver can choose to save energy in slow corners and deploy it all on one critical straight, or spread it evenly across a lap.

The strategic implications are enormous. [Kimi Antonelli](/drivers/antonelli) has been particularly adept at timing MOM deployment in the final stint of races, using saved energy to defend or attack at the optimal moment. This rewards racecraft and intelligence, not just raw speed.

New Engine Formula

The 2026 power units split roughly 50/50 between internal combustion and electrical power, up from roughly 70/30 in 2025. The V6 turbo-hybrid architecture remains but the MGU-H (heat energy recovery) has been removed, simplifying the power unit.

New manufacturers have entered: Audi builds its own power unit for its team. Ford partners with [Red Bull](/teams/red_bull) Powertrains. Cadillac joins as the 11th team using a Ferrari customer power unit. Honda returns as a works supplier for [Aston Martin](/teams/aston_martin). Alpine dropped the Renault power unit and switched to Mercedes supply.

The field now runs five power unit manufacturers: Mercedes, Ferrari, Red Bull-Ford, Audi, and Honda-Aston Martin.

11 Teams, 22 Cars

For the first time since 2016, the grid has 11 teams and 22 cars. [Cadillac](/teams/cadillac) entered with Valtteri Bottas and Sergio Pérez as their driver lineup, using Ferrari engines.

The Result So Far

Three races in, the regulations appear to be working. [Mercedes](/teams/mercedes) leads the constructors but [Ferrari](/teams/ferrari) and [McLaren](/teams/mclaren) are competitive. The top seven drivers are separated by 48 points after three rounds — closer than any of the last four regulation changes at the same stage.

Active aero has reduced the "dirty air" problem that plagued earlier generations. Overtake Mode has produced more lead changes than DRS did in the same races. MOM has added a strategic dimension that rewards driver intelligence. Early verdict: the FIA got this one right.
