At the 2026 Australian Grand Prix, Charles Leclerc took the lead from George Russell, lost it, regained it with Overtake mode, and then had to defend again. Russell eventually passed him at Turn 3, only for Leclerc to use the run through Turns 9 and 10 to get back ahead. The lead changed hands repeatedly in the opening laps, and the new electrical rules were directly involved in the fight. (formula1.com)
That is the clearest early example of what has changed about overtaking in the 2026 Formula 1 regulations. The battery is no longer merely something engineers manage in the background. In a close fight, it can determine when a driver can attack, whether the attack succeeds, and whether the attacker has enough energy left to defend the next corner or straight.
The 2026 cars give electrical power a much larger role
The fundamental change is the scale of the electric contribution to the power unit.
The 2026 regulations increased the MGU-K's maximum electrical power to 350 kW, while the internal-combustion engine's contribution was reduced substantially compared with the previous generation. The MGU-H was also removed. The result is a power unit in which electrical energy has become a much more consequential part of the lap. (fia.com)
That energy comes from the Energy Store and is replenished through the MGU-K's energy recovery. Under the original 2026 framework, the system could recover up to 8.5 MJ per lap, subject to the regulatory conditions. The FIA subsequently reduced the maximum permitted recharge to 7 MJ from the Miami Grand Prix onwards, partly to reduce excessive harvesting and encourage more flat-out driving. (fia.com)
This creates a simple strategic problem with complicated consequences: every unit of electrical energy used to attack has to come from somewhere.
Overtake mode is not simply the old DRS with a new name
The most visible replacement for DRS is Overtake mode, but mechanically and strategically it works differently.
Under the original 2026 concept, a following car within the required detection condition could use additional electrical deployment to attack. The leading car's normal electrical deployment tapers at high speed, while the chasing car receives a higher level of electrical assistance through the override system. The FIA originally described 350 kW of deployment for the following car up to a higher speed threshold, together with an additional 0.5 MJ of available energy. (fia.com)
The important distinction is that this is not simply opening a rear wing and reducing drag.
The advantage comes from putting more electrical power into the car at precisely the point where the driver needs acceleration or top speed.
That makes the timing of the attack more complicated. A driver might have the theoretical opportunity to pass but decide not to use the available energy immediately. Saving it for a later straight, or for the braking zone where the move is more likely to stick, can be more valuable than gaining a position temporarily.
Australia showed why the first pass does not necessarily end the battle
The opening race supplied an unusually clean demonstration.
Russell and Leclerc repeatedly fought over the lead. Leclerc used Overtake mode to retake first place after Russell had passed him, while Russell later found another way past at Turn 3. Leclerc then recovered the position through Turns 9 and 10. (formula1.com)
That sequence matters because it shows the weakness built into an energy-based overtaking system.
A driver can spend electrical energy to complete a pass and still be vulnerable afterwards. If the rival has preserved more battery, the original attacker may have gained the position but lost the tactical advantage.
This is why some 2026 battles have produced what has been described as "yo-yo racing": one car uses its electrical advantage to pass, then finds itself vulnerable when the available deployment runs down and the other car attacks on the following straight. (espn.com)
It is not necessarily bad racing. But it is different racing.
The best overtake can be the one a driver delays
This is where battery deployment starts looking less like a button and more like race strategy.
Suppose two cars are closely matched. The chasing driver has enough energy to attack on the next straight, but the corner at the end of it is not particularly favourable for completing a pass. Using the battery there may put the driver alongside or ahead, but leave too little energy for the next acceleration zone.
Waiting can be faster.
The driver might instead remain close, force the leading car to spend its own electrical deployment defensively, and then attack at a circuit location where the braking zone makes the position easier to secure.
That calculation is not entirely new. Formula 1 drivers have always managed fuel, tyres and hybrid energy. What has changed is how directly that management now affects wheel-to-wheel combat.
Max Verstappen argued early in the season that traditional overtaking had been replaced to some degree by the ability to deploy battery power effectively. ESPN's assessment was more measured: the fundamentals of race craft had shifted, with energy timing becoming another strategic layer alongside braking and positioning. (espn.com)
Boost creates another layer of defence
Overtake mode is not the only electrical tool.
Drivers also have Boost, which can provide additional electrical power independently of the specific overtake mechanism. The distinction matters because a driver defending position can use energy to prevent the attacker from getting close enough to exploit an overtake opportunity.
The Silverstone Sprint provided a particularly clear example.
Kimi Antonelli spent the opening laps of the 17-lap race behind Lewis Hamilton. On Lap 8, Antonelli used Boost to surge past Hamilton on the Hangar Straight. Hamilton had earlier used his own Boost when Antonelli threatened to attack, delaying the move. Antonelli ultimately waited, then used his available electrical advantage to make the decisive pass. (formula1.com)
Antonelli's explanation was revealing. He said he had been close enough to use overtake mode but saw Hamilton use Boost, so he decided to wait. Later, he used everything available and completed the move.
That is the tactical heart of the new system: the driver is not simply deciding whether to overtake. The driver is deciding when the electrical advantage is worth spending.
The FIA has already had to tune the system around real racing
The opening races exposed some consequences that were not obvious on paper.
The FIA and teams agreed a package of changes after the first three events of 2026. From Miami, the race regulations limited MGU-K deployment to 350 kW in key acceleration zones, including overtaking zones, and 250 kW elsewhere. Race Boost was also capped at an additional 150 kW, or the car's existing power level at activation if that was higher. (fia.com)
Those changes are significant because they show that the 2026 energy model is not a fixed recipe.
The FIA is effectively shaping where and how the electrical advantage can appear. The objective is to preserve an overtaking benefit without allowing the closing speed between two cars to become excessive.
That makes circuit characteristics more important too. A track with long acceleration zones, heavy braking areas and enough opportunities to recover energy can produce a very different battery game from a circuit where harvesting is difficult.
At Suzuka, for example, Kimi Antonelli expected overtaking to be harder than at Melbourne or Shanghai because the circuit has fewer long straights followed by heavy braking zones. He also pointed to the importance of having enough opportunity to harvest and deploy energy. (skysports.com)
Battery management can change the value of a corner
The most interesting consequence is that a corner's strategic value is no longer determined solely by whether it is fast or slow.
A driver may deliberately manage the car through a section of track to recover energy. Early in 2026, drivers were sometimes required to lift and coast or use what became known as "superclipping" to recharge the battery. These compromises could cost lap time immediately while creating a larger deployment advantage later. (espn.com)
The FIA's April changes specifically targeted excessive harvesting, reducing the permitted recharge and changing the limits around superclipping. The stated goal was to reduce the amount of time drivers spent sacrificing performance simply to replenish the battery. (fia.com)
So a corner can now have two values.
There is the obvious value: how quickly a driver can take it.
Then there is the electrical value: how much energy the car can recover there, how much deployment that energy can support later, and whether using it in that later section creates an overtaking opportunity.
The driver who manages the battery best may control the battle
That does not mean every 2026 overtake is decided by battery percentage.
Tyres, aerodynamic performance, traction, braking stability, car positioning and outright pace still determine whether a driver can get close enough to attack. And the exact benefit of electrical deployment varies by circuit and by how the teams configure their cars.
But the early races have established something that was theoretical before the season began.
In Australia, battery deployment was part of the repeated exchanges between Russell and Leclerc. At Silverstone, Antonelli explicitly timed his winning Sprint attack around Hamilton's use of Boost. In Japan, drivers were already talking about how the circuit's layout would constrain the opportunities created by the new system. (formula1.com)
That changes the meaning of an overtaking battle.
In the old DRS era, the key question was often whether the chasing car could get within range and then exploit the designated activation zone. In 2026, the more useful question is becoming: who can force the other driver to spend electrical energy first, and who still has enough left when the decisive braking zone arrives?
That is why the battery can decide an overtaking battle before either driver actually makes the move. The winning decision may happen several corners earlier, when one driver chooses to spend energy and the other chooses to wait.
