Mercedes shocked the competition with a one-two victory in qualifying for the Australian Grand Prix. Even worse was their huge lead of eight tenths of a second over the rest of the field. Ferrari, Red Bull and McLaren offered different explanations. The truth is that Mercedes has the best energy management.

This is what Formula 1 feared most. One team is entering the new season with a huge advantage. Just like in 2014 at the start of the first hybrid era. Then, as now, Mercedes thrashed the competition. George Russell and Andrea Kimi Antonelli seemingly effortlessly placed their Silver Arrows on the front row of the grid in qualifying for the Australian Grand Prix (7 March). Antonelli was driving a car that had been a write-off just three hours earlier. Everyone pitched in to patch up the Mercedes with start number 12 after a 170 km/h crash in turn 2 so that it could qualify. Optimising the setup was out of the question.

So George Russell was the sole benchmark for the competition. ‘He was driving in another world,’ marvelled Ferrari team boss Frédéric Vasseur. The Englishman's time advantages underlined this impression. Russell was 0.785 seconds faster than Red Bull, 0.809 seconds faster than Ferrari and 0.862 seconds faster than McLaren. It is little consolation that the chasing pack is as close as it was last year. ‘Russell can already be congratulated on the title,’ was the frustrated sentiment in the paddock.

Red Bull believes it can catch up

When asked why the Silver Arrows are so dominant, everyone had their own answer. McLaren blames energy management, where it still lags far behind the factory team. Ferrari blames the Mercedes engine, which operates with more compression than all other engines. Red Bull says it loses time evenly distributed across the course. Isack Hadjar surprised friends and foes alike in his first race for Red Bull with the third-fastest qualifying time.

Red Bull's technical director Pierre Waché remains optimistic despite the significant time gap: ‘The battle is not over yet. The gap can be closed.’ The Frenchman bases his theory on the fact that Max Verstappen was only three tenths of a second off the fastest time. But the Dutchman ended up in the gravel trap at the first corner just 300 metres into his first qualifying session. He fell victim to the new technology. Red Bull's energy management system was apparently programmed to recover too much energy when braking. This caused the rear wheels to lock up. Interestingly, Waché does not see the engine as the area most in need of improvement. ‘We have more scope with the chassis.’

Ferrari loses more time with its engine

Ferrari sees its disadvantage in the engine. ‘In the corners, we were sometimes faster than the Mercedes,’ analysed Vasseur. According to its opponents, the Mercedes V6 turbo is superior because it runs with more compression than the other engines. The competition expects a loss of up to 15 hp. That is why the FIA was forced to measure compression in cold and hot conditions from 1 June onwards. This will not make much difference because Mercedes will continue to achieve the permitted compression ratio of 16:1, but its opponents will not. Red Bull is likely to lose the least and is therefore holding back on its actionism.

However, those who are lagging behind with their engines still have another opportunity to catch up. After six races, the FIA will investigate the extent to which individual engines are responsible for the loss of time. If this exceeds a certain limit, manufacturers will be allowed to retrofit. There will be more test bench time and exemptions from the budget allowance.

Ferrari was beaten below its true value. The red cars performed well over long stretches of the practice days. And when Lewis Hamilton set the second-fastest time in Q1 on medium tyres, Ferrari was firmly expected to be Mercedes' main rival. But then Vasseur once again struggled with the tyre preparation. ‘We tried one warm-up lap, then two, but didn't get it right at the crucial moment. There was more in it.’

McLaren in the learning phase

McLaren cannot blame the engine. Like the factory team, the defending champion has a Mercedes V6 turbo in the rear. It must be identical in terms of its specification and characteristic maps. However, customers are free to set the parameters for energy management. Team boss Andrea Stella therefore takes responsibility. ‘We still have some shortcomings in how we use the engine and energy to achieve the best possible lap time. If we had used the engine better, third and fourth places would have been possible.’

McLaren is still in a learning phase, says Stella, and is using GPS measurements to look very closely at how and where Mercedes stores and retrieves its energy. This is not quite as trivial as it sounds. ‘There are three ways to charge your battery: when braking, with super clipping when coasting, and when the driver takes his foot off the accelerator. The speed at the exit of the corner shows us how much power the individual teams are drawing when accelerating.’

Stella admits that the factory team is starting the season with a knowledge advantage when it comes to operating its engine. When designing the power unit, he naturally already had in mind how best to use the energy. ‘We have a steep learning curve ahead of us to do just as well. This also applies to the drivers, who have a major influence on energy management.’ However, the Italian also admits: ‘Mercedes was faster than us in most of the corners.’ The first major upgrade is still a long way off. Its deployment depends on whether or not the races in Bahrain and Saudi Arabia are cancelled.

Russell slow at all measuring points

The difference factor remains energy management. This is also shown by the speed measurements. George Russell was at best midfield at the four measuring points. At the finish line, he was only in 15th place with 301.3 km/h. Liam Lawson in the Racing Bulls was 17 km/h faster there. Red Bull, Ferrari and McLaren also outpaced the Mercedes at the finish line. At the end of the home straight, Russell was only twelfth at 297.9 km/h. Again behind Ferrari and Red Bull, but just ahead of McLaren. This suggests that Russell's Mercedes went into super clipping earlier. The lesson to be learned from this is that the home straight was obviously not that important to Mercedes.

At the first sector boundary just before turn 4, Russell reached a speed of 273.4 km/h. That was eighth place. Isack Hadjar flew over the induction loop 15 km/h faster. Lewis Hamilton was also faster at that point. Nevertheless, Russell made up most of the time between turns 4 and 6. Mercedes obviously rationed its power at other points.

This was also evident at the second sector boundary on the back straight. Russell could not get beyond 14th place with a speed of 287.8 km/h. Of his direct rivals, only Oscar Piastri was slower. Lewis Hamilton was 15 km/h faster than his former teammate. Hadjar was only slightly better. The snapshots give the wrong impression, because Russell won all sectors, albeit by a narrow margin. The competition was far from this consistency. In sector 1, Ferrari came closest to Mercedes, trailing by 0.181 seconds. In sector 2, it was Red Bull, trailing by just 0.028 seconds. McLaren came out on top as the second-fastest car in sector 3. Piastri was 0.152 seconds behind Russell in the section with the most corners.

Conclusion

What can we learn from this? The season isn't over yet. Mercedes' lead is mainly down to using energy more wisely. That's something that can be learned. The advantage of combustion engine power is smaller than it's made out to be. Otherwise, Mercedes' customer teams McLaren, Williams and Alpine would be benefiting more from it. And Mercedes isn't miles ahead in terms of chassis either. Ferrari is at least on a par with them in that respect.

Audi showed up at the Bahrain test with a completely redesigned car. The side pods in particular are unrecognisable. We present the first images of the B version.

The Audi factory team is brand new to Formula 1. But when it comes to development work, the new German-Swiss alliance is already way ahead. The engineers have built two completely different cars in a very short time. One for the shakedown week in Barcelona. And one for further testing in Bahrain.

Observers were amazed when the revamped R26 rolled out of the garage at the start of test driving on the Sakhir Grand Prix circuit on Wednesday (11 February). Under the watchful eyes of project manager Mattia Binotto and technical director James Key, a fundamentally redesigned car took to the track.

‘I think it's fair to call this a B version,’ Binotto grinned mischievously. ‘Don't ask what's new! Everything is new.’ The first thing that catches the eye, of course, are the side pods. The bulbous cooling intakes from the Barcelona week have disappeared. They have been replaced by ultra-slim vertical scoops.

The result is somewhat reminiscent of Mercedes' so-called ‘Zeropod Concept’. At the start of the last regulation era, the Silver Arrow team wanted to shock the competition with ultra-slim bodywork.

Zeropod flops at Mercedes

But the solution backfired. It didn't work with the complicated underbodies. Now the underbodies are much simpler in design. And Audi is making a second attempt with a modified concept. The small bump protruding from the panelling at cockpit level is the best indication of just how slim the R26 really is. This is where the side crash structure is located. Its position is mandatory for all cars.

However, Nico Hülkenberg's new company car is not quite as extreme as the old Mercedes. From above, you can see a small channel that directs air over the side pods to the diffuser. Another new feature is the cooling fins carved vertically into the bonnet. They prevent heat from building up under the tightly fitting carbon skin.

A version still in the 2025 budget

Many changes can also be seen on the nose and front wing. The dark contrasting adjustment mechanism used to retract the upper flaps on the straights is particularly striking. It was not yet present on the base car used in Barcelona.

For those who now fear that Audi has already used up its entire development budget for the 2026 season by building two completely different cars, we can give the all-clear. Binotto confirmed that the parts for the A version from the shakedown in Barcelona were all built last year and accordingly included in the budget cap. This leaves room for further upgrades.

Conclusion

Audi showed up at the test drives in Bahrain with a completely redesigned car. The ultra-slim side pods with vertical cooling inlets are particularly eye-catching. You can find the latest detailed photos in the gallery.

The root of all evil seems to be the limited amount of battery. I wonder if the FIA will make a last minute change to allow for a larger capacity battery.

The electric drive delivers plenty of power but very little energy under the new Formula 1 regulations. We do the maths and ask Lando Norris what this means for longitudinal dynamics and driving style. Spoiler: full throttle and braking are less popular, recuperation more so.

Nominally, the new Formula 1 regulations promised no decline in performance compared to the 1,000 hp in qualifying in 2025. Initial assessments by those involved even pointed to a slight increase in performance. Torque in particular could benefit from the new 50:50 distribution between combustion engines and electric motors in the power units: 300 per cent more power from the particularly high-torque electric motors could bring a significant increase in power.

The new regulations also started the 2026 season with advance praise: the cars look more aggressive, are smaller and lighter. This should make them more agile on the track and offer more action. In addition, the new active aerodynamics should make overtaking easier.

However, the first test laps in Barcelona raised doubts as to whether the new drive technology might require a few unattractive concessions: ‘We have to lift and coast even on qualifying runs,’ reports Esteban Ocon, for example, referring to the qualifying simulations that his Haas team ran in Barcelona, which took some getting used to. ‘It felt strange at first. But we had already practised it in the simulator. After one lap, I had got the hang of it. Now it feels strange not to do it. We use lift-and-coast so often that you quickly get used to it in your driving style,’ said the Frenchman.

New F1 drive: powerful but low on energy

‘Lift and coast’ is the name given to a driving style that saves fuel and protects the brakes. The driver lifts off the accelerator before the actual braking point (“lift”) and lets the car roll into the corner (‘coast’). This reduces fuel consumption and allows the brakes to cool down. With the new hybrid drives, however, the goal is not to save fuel, but to consume less energy from the battery – because even in qualifying, it is apparently not enough for full-throttle attacks up to the braking point.

A glance at the key data for the new power units explains the cause of the problem: although the new regulations allow the power of the electric drive to almost triple from 120 kW to 350 kW (476 hp), they do not allow for a higher battery storage capacity. It remains at a meagre 4 megajoules, which corresponds to 1.11 kWh. That is hardly more than the starter battery of a luxury diesel car can store. Its starter motor has an output of around 2 kW – so with the F1 battery, it could be operated for around 30 minutes.

The 350 kW engine of the Formula 1 drive, on the other hand, completely drains the mini battery in just over eleven seconds at full load. This is an outstanding discharge capacity for the battery – but not for long. This is because power is work or energy per unit of time – short times therefore increase the power in this fraction, but the amount of energy remains low for short times.

By way of comparison, the smallest battery for a VW ID.3 can store and release around 50 times as much energy as the F1 battery. In real-world driving conditions, the VW can travel around 350 kilometres with 150 kW of power. At a realistic cruising speed of 100 km/h, the compact car would be on the road for 3.5 hours until the battery is empty. Of course, driving at a steady 100 km/h is not very helpful for Formula 1. But eleven seconds is too short even for full-throttle driving, as you can see.

Where does the energy for the electric drive come from?

The power units in F1 are hybrid, but not plug-in hybrid drives. This means that the batteries cannot be charged with external energy during races. They can only be charged via recuperation while driving. Electric car drivers are familiar with this: unlike combustion engines, electric motors can recover kinetic energy.

The electric motor then acts as a generator, driven by the (still) rolling wheels, charging the battery during moments of coasting. The enormous (current) charging speed of the battery and the high power output of the motor help here – which, incidentally, is why most electric cars have higher performance values than comparable combustion engines, as this means that as little kinetic energy as possible is lost even at high speeds.

But just as quickly as the battery empties, it recharges during recuperation. If it is 100 per cent charged, it may not be able to absorb any more kinetic energy and will have to give up accordingly early on the next power demand.

As mentioned at the outset, Lift and Coast has also been used to protect the brakes. Road cars with electric drives also benefit from recuperation here. In everyday use, more than 90 percent of braking manoeuvres can be performed without pressing the pads against the brake disc in most models. Due to the dynamic axle load distribution, the front axle can absorb more recuperation energy – after all, it also carries the more powerful conventional brake.

However, Formula 1 cars with their rear-wheel drive do not recuperate on the front axle. This means that recuperation potential is also lost in the naturally dynamic driving style of the premier class of motorsport. This can only be compensated for with the combustion engine if it does not convert all its power into propulsion, but instead drives the electric motor, which then acts as a generator. From an energy perspective, this is complete nonsense. And it's not really a way to protect the brakes: the combustion engine needs fuel to charge the battery.

This is what Lando Norris has to say about the new technology

Reigning world champion Lando Norris explains how the new powertrain feels on the track and what it demands of the drivers. Regarding performance, he says: "When accelerating in third or fourth gear, if there is enough grip, it really pushes forward. If recuperation didn't start at some point on the straights, we would easily reach 380 km/h. So the cars could do much more."

As far as the size of the battery is concerned, he confirms the impact of the key data of the new power units: "We have a lot of electric power, but it doesn't last long. The question is where to best use the energy and where to best recuperate. In individual cases, it may be necessary to shift down before the end of the straight. We are still trying to figure out how to make the best use of the battery."

According to Norris, managing the low energy content of the small battery is likely to present drivers with exciting challenges: "It could lead to chaotic scenes, depending on where the drivers press the boost button. In Barcelona, there are many places where you don't use the battery at all. In turns 5 to 7, there is a short full-throttle section. If you activate boost power there, you can overtake another driver before turn 7. That wasn't possible before," explains the Englishman.

‘But then you're defenceless on the way to turn 10. As the driver behind, however, you can exert more pressure. That could lead to better racing. If you want to overtake, you always pay a price afterwards. The driver behind can then use additional energy. That could lead to a yo-yo effect, with the cars overtaking each other back and forth,’ the McLaren driver speculates about future racing.

What will the fans get to see?

Drivers may quickly adapt to the new requirements, and more overtaking manoeuvres sound appealing. However, the predictability of drivers' behaviour and manoeuvres could fall by the wayside.

Traditionalists will also point out that qualifying sessions are so spectacular precisely because everything is pushed to the limit on a single lap. The fact that drivers are now forced to lift off before the braking zones in order to save or recover electrical energy is likely to cause irritation, to say the least.

Conclusion

Recuperating instead of going full throttle, coasting instead of slamming on the brakes. The mini battery in the new power units could shake up the driving style and battle tactics of Formula 1 drivers. Fans may see more action and overtaking manoeuvres. But they may not be able to understand them so easily, as the tactics of energy recovery are (still) difficult to read on the track.

It's not too different from their previous liveries. British racing green is always pretty. It's hard to go wrong with it. I'm disappointed with the Cadillac, though. They had the option of using gold or yellow, but instead they went with the boring black and white.
