Barcelona earlier this month, according to a report. This year, the
FIA has implemented the Additional Development and Upgrade
Opportunities – or ADUO – system to help engine manufacturers who
are behind in the pecking order catch up. It also intended to
ensure that the differences between the power units did not become
too great, as was the case for many years at the start of the V6
era. However, ADUO has already caused a stir as the FIA deemed Red
Bull as the benchmark, although the findings of the opening phase
have not yet been made public. A review of ADUO is already underway
by the FIA, as they want to be as precise as possible with the
measurements. But it seems that one manufacturer has already taken
advantage of the ADUO findings, as Audi introduced an engine
upgrade in Barcelona. It was communicated on Friday that both Nico
Hulkenberg and Gabriel Bortoleto had been fitted with new engines
for the grand prix weekend, a switch that went largely unnoticed.
However, according to the Italian branch of Motorsport.com , the
engines were new and improved, upgraded as part of the ADUO system.
It is news that has surprised many in the paddock, as it seems Audi
had prepared well in advance to introduce the upgrade. In Austria,
more teams are set to introduce updates. Ferrari is set to bring an
improved engine, while RacingNews365 has also learned that Honda
plans to implement some minor changes.
