The fallout from the FIA’s first Further Improvement and Improve Alternatives (ADUO) evaluation continues to ripple via the Formulation One paddock, and Mercedes arrive on the Barcelona‑Catalunya Grand Prix with their two drivers providing strikingly completely different interpretations of the governing physique’s engine findings.
Throughout the Monaco Grand Prix weekend, it emerged that the FIA’s preliminary information positioned Pink Bull Ford Powertrains on the prime of the inner combustion engine hierarchy, adopted by Mercedes, Ferrari, Audi and Honda.
The outcome shocked many observers, given Mercedes’ dominant early‑season kind and the broadly held perception that the Brackley‑Brixworth package deal had set the benchmark for 2026.
But inside Mercedes, the response has been something however uniform.
“I wasn’t shocked”
George Russell, who sits third within the championship however has endured a run of misfortune in latest races, insisted that the FIA’s rating aligned with what the producers already understood concerning the combustion‑solely analysis.
“I wasn’t shocked as a result of all of it agreed with the producers,” Russell stated. “The ADUO relies on the combustion facet of the facility unit, we knew from Barcelona [testing], Pink Bull seemingly had a extremely robust combustion engine.”
Russell argued that Mercedes’ latest efficiency surge has been pushed primarily by the standard of the chassis quite than any perceived engine benefit.
“The performances we’ve proven lately as a crew has simply proven how robust our chassis is. It’s been a lot discuss round our engine… the engine is nice, the chassis is unimaginable.”
His feedback mirror a broader sentiment inside the crew that Mercedes’ aggressive edge within the opening section of 2026 has come from aerodynamic effectivity, tyre administration and mechanical grip quite than outright energy unit superiority.
“I’m shocked”
Championship chief Andrea Kimi Antonelli, nonetheless, provided a contrasting view. The 19‑yr‑outdated Italian, who leads Russell by 68 factors after a blistering begin to his rookie season, admitted he didn’t count on Pink Bull to be ranked forward of Mercedes.
“I feel our PU may be very robust, however for certain there have been causes behind it,” Antonelli stated. “I’m shocked by the outcomes.”
Whereas Russell emphasised the power of the chassis, Antonelli centered on the lengthy‑time period implications of the ADUO system and the event alternatives it now grants Mercedes.
“The crew now might want to begin engaged on attempting to see and discover the place we are able to achieve much more efficiency. So, it’s a course of that’s not going to be quick time period, it’s going to be a protracted‑time period course of as a result of nonetheless to seek out extra efficiency on the engine takes time.”
He additionally praised the work already completed by Mercedes Excessive Efficiency Powertrains, stressing that the crew is properly‑positioned to capitalise on the improve allowance.
“Positively the crew has completed an unimaginable job already with the PU, and I’m certain they may put their most effort to try to extract much more efficiency now that we get this profit.”
