Finally, the wait is over. On Sunday, March 8, as International Women’s Day is celebrated around the world, the new era of Formula 1 will officially begin. The 2026 season marks a significant technical revolution, and while drivers will have to deal with new steering wheel settings and a far more sophisticated way of managing the energy they harvest and deploy from the batteries, we fans will also need to become familiar with a new and equally sophisticated technical terminology.
From a practical standpoint, there are three key concepts that must never be confused with one another (and we stress this because it is very easy to mix them up).
Active aerodynamics (usable in “straight mode”)
Let’s start from the fundamentals. In Melbourne, as we previously reported, active aerodynamics will make its official debut. From 2026 onwards, Formula 1 cars are equipped with movable front and rear wings that open on the straights to reduce drag, place less stress on the power unit, and allow for higher top speeds.
Attention: active aerodynamics can be used at all times during the Grand Prix, on every single lap. It is therefore not a system specifically designed to help drivers defend or attack a rival. It is simply there, integrated into the car’s performance philosophy, allowing the car to be more efficient and faster on the straights whenever permitted. Drivers will use it as part of normal lap execution.
So, where on the circuit can it be activated? The FIA will define the activation zones race by race. At Albert Park in Melbourne, there will be five “straight mode” zones in normal grip conditions (dry track). These will be reduced to three zones in low-grip conditions, such as rain or other circumstances that reduce adhesion. For example, in Sakhir, strong winds have previously blown sand onto the circuit, decreasing overall grip levels.
In the official track map provided by the FIA, the areas marked in red correspond to normal grip conditions, while those highlighted in blue apply to low-grip scenarios. If you look closely, the blue zones are also shorter than the red ones in sections A1, A2 and A3. This ensures a safer and more controlled deployment of active aerodynamics when track conditions are less predictable.
Energy management – the difference between Boost and Overtake Mode
The most complex aspect to understand concerns energy management. First and foremost, Boost and Overtake Mode are not the same thing. In both cases, the driver requests additional power from the power unit, but the quantity, logic, and regulatory framework behind each system are different.
Boost
Boost is always available, on every lap. The driver can use Boost at their own discretion, whether to attack or to defend. When activated, the system deploys the maximum available power derived from the combination of the internal combustion engine and the electric motor.
The only limitation in this case is the amount of energy that the MGU-K can recover during a lap: 9 MJ. However, consistently reaching that figure is far from straightforward, and this is where the real challenge lies for the drivers. Energy harvesting efficiency depends on braking phases, circuit layout, and driving style.
Out of those 9 MJ, 8.5 MJ can be deployed via Boost, and this can be done on every lap, regardless of the position on the track. In essence, Boost represents the standard high-performance deployment mode available at all times, provided the battery state of charge allows it.
Overtake Mode (Override) – the replacement for DRS
Overtake Mode, also known as Override, is the true successor to DRS. If the chasing driver is within one second of the car ahead at the designated detection point, they will be entitled to an additional 0.5 MJ of deployable energy for the following lap.
Taking Albert Park as an example, the detection point and the activation point (marked in green for Overtake Mode) are positioned in sequence at Turn 14. Being within one second of a rival at Turn 14 effectively grants the pursuing driver an extra 0.5 MJ to use on the next lap.
This is where the complexity increases. If a driver wants to benefit from Overtake Mode for two consecutive laps—assuming the gap requirement is still met—they must still manage to recover the full 9 MJ demanded by the power unit. Energy recovery and deployment therefore become a delicate balancing act, particularly in intense wheel-to-wheel battles.
Separate power delivery functions for Boost and Overtake Mode
The power output is managed electronically by the FIA-standard ECU and delivered according to specific formulas that follow a structure similar to this:
P = C(v) − d(v) × v
In this equation, P represents power measured in kilowatts (kW). The constants C and d vary significantly depending on the car’s speed and whether Boost or Overtake Mode is being used. The constant d is also multiplied by the instantaneous speed (v) of the car.
Of course, the control unit monitors and regulates everything in real time. The driver’s role is simply to request additional power via the steering wheel controls. We have deliberately avoided going into excessive detail by listing the exact values of C and d in the equation because, based on current understanding, the FIA reserves the right to adjust these parameters from Grand Prix to Grand Prix, depending on how difficult overtaking is expected to be at a given circuit.
This flexibility allows Formula 1 to fine-tune the competitive spectacle, ensuring that overtaking opportunities remain viable without compromising safety or fairness. As a result, understanding the distinction between Boost and Overtake Mode will be essential for interpreting race strategies, defensive maneuvers, and attacking moves throughout the 2026 season.
