Red Bull has requested additional checks on the FIA's initial ADUO engine power rankings after being placed at the top. Team principal Laurent Mekies said no data sample indicates an advantage over Mercedes.
The FIA informed manufacturers of the results in Monaco, with a public announcement still pending. Red Bull-Ford Powertrains asked for further verification of sensors and data points used in the assessment covering races through the Canadian Grand Prix.
Mekies said after the Barcelona Grand Prix that the team accepts the rules focus solely on internal combustion engine power. He added that Red Bull sees no single data sample showing an advantage over Mercedes and wants a deeper conversation with the FIA.
The initial ranking gives Mercedes one upgrade opportunity while Ferrari, Audi and Honda receive two. Mekies noted that on-track qualifying results align with Red Bull's own assessment of its engine performance across different circuits.
