Key Highlights:
- Red Bull is in active talks with the FIA to refine the 2026 Additional Development and Upgrades Opportunities (ADUO) system after contentious performance evaluations.
- ADUO metrics deemed Red Bull the benchmark internal combustion engine manufacturer, awarding them zero upgrade tokens while handing one to Mercedes and two each to Ferrari, Audi, and Honda.
- Team principal Laurent Mekies highlighted Red Bull’s rapid development cycle, which guided Max Verstappen back to victory in Malaysia despite early-season deficits.
Red Bull Racing is actively collaborating with the FIA to modify Formula 1’s new Additional Development and Upgrades Opportunities (ADUO) mechanism following controversial initial evaluations, according to team principal Laurent Mekies. The ADUO framework, introduced under the 2026 technical regulations, evaluates the V6 engine outputs across all power unit manufacturers at the end of each quarter to award developmental upgrade tokens to struggling competitors.
Although paddock consensus anticipated Mercedes would be established as the performance benchmark following its commanding start to the 2026 rules cycle, the governing body’s methodology instead ranked Red Bull at the top. This determination arose because the ADUO system exclusively evaluates internal combustion engine (ICE) outputs, disregarding the broader hybrid parameters where Mercedes has demonstrated comprehensive strength.
Flaws in the 2026 Power Unit Assessment Process
The FIA’s reliance solely on peak ICE figures has triggered high-level discussions regarding structural adjustments for 2027, with FIA single-seater director Nikolas Tombazis acknowledging the presence of “weaknesses” in the system.
Laurent Mekies voiced his clear reaction to the governing body’s preliminary assessments and outlined the constructive approach the team has taken since.
“We were surprised and a bit more than that at the initial evaluations from the FIA,” said Mekies. “We made our case. We showed them why we felt it was not capturing the right picture. We are having discussions with them on what can be improved in the methodologies for next year with them.”
Mekies continued: “That’s where we are. Then at some stage, we like to say in Red Bull Racing we like to reduce the noise and concentrate on pure racing. So at some stage, you concentrate on yourself and you keep pushing with what you have. Ultimately, we prefer to be in a position to have a strong engine and no ADUO rather than a weak engine and claiming the ADUO.”
Token Distribution and Red Bull’s Workaround Strategy
Under the latest evaluations calculated by the governing body, Mercedes was granted one token after being calculated at 2-4% adrift on peak power. Meanwhile, Ferrari, Audi, and Honda were each allocated two development tokens for sitting more than 4% off the pace. Red Bull received zero tokens under the metric.
Despite the lack of hardware adjustment allowances through ADUO tokens, Mekies explained that development routes remain wide open for the operation’s inaugural campaign as an independent power unit builder.
“Whilst ADUO is trying to somehow estimate the peak power of the ICE, there is a huge number of other performance factors that can be developed and improved,” Mekies added. “Especially in the first year for us as a power unit manufacturer. So, of course, the guys have been doing huge jobs at developing the package for drivers, operating windows. There is huge development work in the background, even though you cannot change the hardware. I guess it’s especially true for us in our very first year of operation.”
Rapid In-Season Turnaround and Recent Performance Gains
The relentless updates to the RB22 yielded significant progress on track, headlined by an extensive package introduced at the Azerbaijan Grand Prix in September. In Baku, Max Verstappen took second place, crossing the line less than a second behind race winner George Russell in the Mercedes. That podium marked Verstappen’s fifth top-three finish across six events, which he swiftly followed by claiming his maiden victory of the 2026 campaign in Malaysia.
“What I take from the Baku upgrade is not so much what it unlocks,” said Mekies. “I don’t think there was anything too specific about that upgrade compared to our previous ones. What I take from that one is that once again, this team has been able to produce an incredible season development.”
“We started on the back foot. But equally, nobody was going to wait for us, and starting from that more than one second [deficit] and being where we are now, I think it’s very much a Red Bull Racing trademark to have this strong in-season development. At some stage, we felt there would be a possibility that we get stuck into that three-tenths mark compared to the best cars. In the end, the guys have been doing a job at 360 [degrees], our chassis side, PU side, to eat up those last three-tenths, which we felt would be the most difficult. The Baku upgrade played a role with that, but it’s part of a more global effort from everyone – chassis side, PU side – to extract more.”
Why This Matters
The debut of the ADUO system represents Formula 1’s formal effort to manage power parity under the complex 2026 powertrain regulations without instituting artificial balance-of-performance mandates. However, evaluating engine parity solely by peak ICE output poses a significant problem in an era heavily dependent on advanced electrical deployment, turbo efficiency, and energy harvesting. The current situation exposes potential competitive distortions: manufacturers fielding faster overall hybrid setups can still access developmental tokens if their ICE alone tracks below the threshold, while outfits with stronger combustion efficiency are frozen out of hardware modifications. Refining this system for 2027 will prove critical to maintaining equitable manufacturer competition.
Frequently Asked Questions
What is the ADUO system in Formula 1?
The Additional Development and Upgrades Opportunities (ADUO) system is a regulatory mechanism introduced for 2026 designed to evaluate V6 engine performance quarterly. Manufacturers identified as lagging behind the benchmark can receive tokens allowing them to introduce corrective engine hardware upgrades.
Why did Red Bull not receive any upgrade tokens?
The system currently monitors only internal combustion engine (ICE) outputs rather than total hybrid system performance. Red Bull was calculated as having the highest peak ICE power, leaving them with zero tokens, while Mercedes received one token and Ferrari, Audi, and Honda received two tokens each.
Is the FIA planning to update the ADUO framework?
Yes. Discussions are ongoing between the FIA and teams regarding adjustments to the evaluation methodologies for 2027, with FIA single-seater director Nikolas Tombazis acknowledging existing weaknesses in how current performance is tracked.
