Red Bull Refutes Claims of Possessing Top F1 Engine, Anticipates Upgrade Window

Laurent Mekies, the team principal of Red Bull Racing, has firmly dismissed the circulating rumours that his outfit runs the most powerful power unit in the Formula One grid. He stressed that Red Bull does not currently sit at the pinnacle of engine performance and therefore looks forward to the chance to narrow the gap when the next development window opens under the new 2026 power‑unit regulations. The 2026 rulebook introduces a performance‑balancing mechanism known as Additional Development and Upgrade Opportunities (ADUO).

This provision is designed to give teams that fall at least two percent behind the leading internal combustion engine (ICE) a chance to develop and upgrade their units during specified periods of the season. The intention is to keep the competition closer rather than allowing a single manufacturer to dominate outright.

Originally, the first ADUO window was slated to begin after the Miami Grand Prix. However, the schedule may be shifted because the opening two races of the year – Bahrain and Saudi Arabia – were cancelled amid the ongoing Middle‑East conflict, compressing the calendar and potentially delaying the upgrade period.

Mercedes has so far dominated the opening three rounds, sitting comfortably at the top of the constructors' standings with a 119‑point advantage over Red Bull, who are currently sixth. Despite this clear points disparity, some media outlets have suggested that Red Bull’s ICE might actually be the strongest on the grid, a claim that would qualify the team for the ADUO benefit. Speaking to Sky Sports News, Mekies was unequivocal: "Is our engine at the level of the very best?

Absolutely not. So do we expect to be in the group that can be given the chance to catch up? Yes, we certainly hope to be in that category." He echoed Mercedes team boss Toto Wolff’s view that ADUO should be a tool for catching up, not for leaping ahead of rivals, and he insisted that the Silver Arrows still possess the premier ICE. The ADUO framework outlines three distinct periods during the season when eligible teams may receive additional development allowances.

To qualify, a team’s ICE must be measured as at least two percent slower than the benchmark set by the top‑performing engine. Wolff has hinted that Honda, which supplies Aston Martin’s power unit, may be the only constructor truly in need of the extra development boost. He placed Red Bull, Ferrari and Audi in roughly the same performance bracket as Mercedes, suggesting a relatively narrow spread among the front‑running manufacturers.

In a separate written interview, Mekies estimated that Mercedes enjoys roughly a three‑tenths of a second per lap advantage over Red Bull, attributing a substantial portion of that gap to the German team’s superior ICE. He noted, "What we see is certainly Mercedes, a long way ahead of most of us.

And yes, you’re right, one guy – Honda – is particularly behind. The other guys are probably quite close to us, Ferrari and Audi, and fair enough, Honda is probably struggling a bit more. To extract the right combustion‑engine performance in a fair way across the teams is very difficult.

I think overall results are probably giving you the best, the most fair picture, of where everybody is at." Red Bull’s shaky start to the season has also fueled speculation about the future of four‑time world champion Max Verstappen with the team. Verstappen has voiced his displeasure with the 2026 regulations and hinted in Japan that he may consider stepping away from Formula 1 after the current year.

Mekies, however, remains optimistic that upcoming upgrades will give Verstappen a car capable of delivering the performance he expects, which in turn should lift his morale. "The Max we see is a fully committed Max. He wants a fast car and he’s helping the team to get a fast car.

He’s bringing all his energy to that," Mekies said. He added that Verstappen’s passion for the sport is evident, noting that the driver has been vocal when he feels changes are required. Looking ahead to the Miami Grand Prix – the second sprint weekend of the season scheduled for May 1‑3 – Mekies believes the forthcoming regulatory adjustments could provide a step forward. "He’s embracing that.

Will it be enough? We have time to see together if it’s going to be enough or not.

We are conscious that the priority is to give him a car he can push with. And this has not much to do with the regs.

We knew we gave him and Isack a very difficult car in the first three races. We need to give him a car he can consistently push with.

Then, after, it doesn’t mean it will be fast enough for positions, but it means he can start to bring his ‘Max effect’ and we can start to build development onto that car. I have every confidence that things may not be fixed for Miami, but the team will get to the bottom of what is limiting us, as they did last year, and you will see more and more smiles on Max’s face." In summary, Red Bull acknowledges that its power unit is not currently the benchmark and welcomes the ADUO system as a fair opportunity to close the performance gap. While Mercedes leads the championship and appears to have the strongest ICE, the upcoming upgrade windows and regulatory tweaks could reshape the competitive landscape, offering Red Bull and its star driver a chance to regain momentum as the season progresses.
