Mercedes delivered a remarkable performance during qualifying for the Australian Grand Prix, putting eight tenths of a second between themselves and their closest rivals. The session clearly highlighted the impressive power output of the engine designed and developed at Mercedes’ Brixworth facility in the United Kingdom. In this technical analysis, we examine why Ferrari and the other power unit manufacturers will likely struggle to close what appears to be a very large gap – at least during the current season – despite the presence of the ADUO program, which in theory should help manufacturers that are currently behind in terms of power unit performance.
Over the past year, there has been extensive discussion about the new Mercedes engine developed for the latest regulatory cycle. In recent months, rumors also emerged suggesting that the Brackley-based team may have found a way to exploit a regulatory grey area, potentially allowing them to operate their power unit with a compression ratio higher than the level officially specified in the regulations. Mercedes team principal Toto Wolff repeatedly stated that the supposed advantage derived from this trick was largely an invention created by rival teams. However, the Australian Grand Prix qualifying session appeared to reveal what many now describe as Pandora’s box.
Mercedes’ advantage lies entirely in the power unit
“The difference at the moment is mainly the power unit. They have more margin than anyone else when it comes to energy recovery. They are the only ones capable of pushing like that on all the straights. Between Turn 8 and Turn 11 – which is practically just a straight – they gain half a second on everyone.”
This was the analysis offered by Italian journalist and F1 expert Federico Albano, a view that was also supported by davidecarblogger: “Mercedes’ deployment is on another level. When Leclerc begins the superclipping phase, Ferrari has 0% battery left, while Mercedes still has a good 29% available to use between Turn 8 and Turn 9. That’s an advantage of around 0.500 seconds just in that section. It’s not a matter of strategy; Mercedes simply has much greater electrical efficiency. There isn’t much that can be done in the short term because power unit development is something far more complex. We’ll see how this energy will be managed during the race, but with such a big advantage it will also be easier for Mercedes to overtake.”
In simple terms, Mercedes appears able to manage the energy available throughout the lap far more effectively than its rivals. This capability is likely also linked to the exploitation of the previously mentioned grey area, which would allow the power unit to operate with a higher compression ratio than what is officially defined in the regulations. For this reason, Ferrari will likely struggle to recover the deficit from an engine perspective, even with the help of the ADUO program.
The only theoretical option would be to replicate the same trick allegedly used by Mercedes, but that possibility is effectively ruled out because the engines were homologated at the beginning of March. Once homologated, the power units cannot undergo structural modifications. From June 1, new hot checks are expected to take place, which in theory should eliminate the grey area currently being exploited. However, at 130 degrees it is unlikely that anything significant will be detected, as the temperature threshold is probably too low to reveal the difference. As a result, Mercedes could effectively continue to benefit from this situation.
Why Ferrari may struggle to recover despite several potential solutions
“From a chassis perspective Ferrari actually shows good signs. It holds its own in the first part of the lap and is even the fastest – by around 0.15 to 0.2 seconds – in the mixed section of sector three, which is particularly demanding on the tyres. But the power unit gap is almost a drama. Perhaps the usage was not optimal after the issues in Q2, but there are around nine tenths of a second lost purely in the power sections. The suffering between Turn 10 and Turn 11 is enormous, and it was like that throughout the entire session. There is a clear hunger for energy there that simply doesn’t arrive because there was no recharge during the superclipping phase, which is exactly the area where Mercedes excels. Charles Leclerc’s delta speed at Turn 11 is 14 km/h lower than George Russell’s.”
This continuation of Federico Albano’s analysis highlights another important detail. The Ferrari SF-26 appears to be a fundamentally well-designed car from a chassis perspective. However, the power unit issue represents both the necessary and sufficient condition that defines competitiveness under the current regulatory cycle.
There has been discussion about the so-called reverse wing that Ferrari plans to introduce during the first races of the season. However, this development cannot realistically be considered a solution to the current problem, and this can be explained through a simple example. Let us imagine that Ferrari had already brought this new wing to Australia. The team would likely have gained a few additional kilometers per hour on the straights, but once the car runs out of available electrical energy and enters recovery mode, the car inevitably slows down. As seen in the second sector, the loss can exceed 50 km/h.
Davidecarblogger also pointed out that when Ferrari had 0% battery remaining, Mercedes still had nearly 30% available and was therefore able to continue pushing while the SF-26 could no longer do so. This clearly demonstrates that the entire issue revolves around energy management within the framework of the current regulations.
Aerodynamic updates will certainly arrive during the season, but they cannot fundamentally solve this problem. The key factor remains energy deployment. The only real potential solution could be to reduce the power output of the electric motor in order to distribute the available energy more unevenly throughout the lap. This possibility has already been discussed, and it remains to be seen what decision the FIA may ultimately take on the matter.
