Red Bull Seeks F1 Development Lifeline as FIA’s New ADUO Decision Looms
FIA ADUO Engine Rankings: Red Bull Tops First Period, Awaits Second Assessment
Although the second ADUO period—Additional Development and Upgrade Opportunities in Formula 1—concluded after the Hungarian Grand Prix, the official results of the first assessment period remain unpublished. During the Monaco race weekend, however, all manufacturers were privately informed of the outcome, which placed Red Bull-Ford Powertrains surprisingly at the top of the rankings.
First Period Results Favor Rivals
Despite Red Bull’s dominant start to the season, the FIA allocated development tokens to its competitors: Mercedes High Performance Powertrains received one token, while Ferrari, Audi, and Honda were each granted two upgrade opportunities. The governing body had prepared a public announcement at that time but withheld it following considerable behind-the-scenes dissatisfaction from Red Bull, with CEO Oliver Mintzlaff directly involved.
The Milton Keynes-based manufacturer had limited avenues to challenge the result. The current system measures only the internal combustion engine (ICE), yet the upgrade opportunities apply to the electrical side of the power unit as well—a structural weakness that cannot be addressed in the short term. FIA single-seater director Nikolas Tombazis explained to media including Motorsport.com that he was open to incorporating additional parameters such as turbo size, but teams and manufacturers pushed to keep the system simple last year.
Consequently, Red Bull could only request a factual review. Team principal Laurent Mekies stated that, in his view, there was “not a single data point” suggesting that Red Bull-Ford Powertrains has the best engine on the grid. That factual check does not appear to have altered the outcome. When asked by Motorsport.com, Tombazis affirmed the accuracy of the FIA’s measurements.
“I think our measurement, in my opinion, has proven to be very accurate,” he said. “With that said, has everything worked fine? No, because obviously people are not happy and so on. Do we need to think about improvements in the future? Yes, I would say so.”
The prevailing paddock sentiment is that manufacturers such as Mercedes and Ferrari strategically managed their performance during the opening race weekends—avoiding showing their full hand—to secure ADUO tokens. Ferrari, in particular, managed to obtain two tokens through this approach.
Second Period Offers Red Bull a Potential Lifeline
Red Bull’s hopes now rest on the second assessment period, which covers races up to and including the Hungarian Grand Prix. According to the prescribed timeframe, the FIA should inform all manufacturers of the results ahead of the Italian Grand Prix at Monza, with an announcement expected this week or early next week.
For Red Bull to receive a token, its internal combustion engine must no longer rank as the best in this second assessment. However, this outcome depends partly on rival manufacturers, who can effectively play a strategic game. If competitors refrain from using their tokens on the ICE and continue to withhold maximum performance at certain events, they could keep Red Bull at the top of the ranking for longer.
Tombazis, speaking before the summer break, expressed skepticism about such a scenario unfolding.
“Well, I don’t think it would be convenient for you to always be below [your maximum power] just to keep getting more opportunities, because what’s the point of opportunities if it isn’t ultimately for you to be on top?”
To qualify for a token, Red Bull’s deficit to the best ICE on the grid during the second ADUO period must exceed 2%. If Red Bull remains top-ranked or its deficit is assessed at less than 2%, it will again receive no upgrade opportunity. In that scenario, the team’s only remaining chance to modify its power unit this season would come in the third period, which concludes after the Mexico City Grand Prix.
Mekies and his team are hopeful of securing an opportunity before then. If successful, every manufacturer will have received at least one token in the first season under the all-new regulations, with clarity expected before media day in Monza.
