Red Bull boss Laurent Mekies wants "extreme certainty" over the pecking order of F1's power unit manufacturers when it comes to the awarding of ADUO.
In Monaco, Lewis Hamilton revealed that his Ferrari team would be receiving two ADUO upgrades, and Mercedes one, after he claimed the FIA's evaluations into the performance of the power units had found Red Bull Powertrains to have the strongest ICE.
The ADUO process only takes into account the power output from the ICE, and not the complex energy and electrical systems, which comprise 50% of the power output.
The FIA still has not formally declared its findings over the awarding of ADUO, as Red Bull's Mekies wants there to be no doubt about the pecking order of Mercedes HPP, Audi, Ferrari, Honda, and his RBPT operation.
'Certainly, you will need to have extreme certainty in the way you are assessing the ICE pecking order," Mekies told media, including RacingNews365.
"That is in order to have the right confidence to give it to the dominant team, and not to the team that is chasing the dominant team, especially when you get relative performance variations from track layout to track layout, that are perfectly consistent with ICE power sensitivity.
"So you go to Canada, with high ICE power sensitivity, we qualified sixth. You go to Monaco, low ICE power sensitivity and qualified four-hundredths from pole.
"You go to Barcelona, high again, ICE power sensitivity, and you qualify sixth again.
"We do not see one single data sample where we estimate ourselves to be higher than the competition, let alone being so consistently above them."
