Red Bull remains F1 engine benchmark after ADUO period two
The FIA’s latest ADUO evaluation confirms Red Bull-Ford as the most powerful F1 power unit, with Mercedes 2-4% down and Audi, Ferrari and Honda more than 4% behind; no new homologations were granted in this cycle, and while Mercedes had token allowances earlier, the standings remain unchanged. The ADUO system, which only considers the internal-combustion engine, has faced criticism, and Red Bull’s advantage on the straight was noted as debate builds ahead of the Italian Grand Prix.
