Audi became the first Formula 1 manufacturer to use the FIA’s new Additional Development and Upgrade Opportunities system, bringing an upgraded power unit package to the Barcelona-Catalunya Grand Prix. The FIA confirmed the rule-compliant update in its Friday power unit document after completing its initial assessment following the Canadian Grand Prix. The package included revised V6 components, new internal combustion engines and turbochargers, along with drivability-focused changes fitted to both cars at Audi’s facilities in Ingolstadt and Hinwil. The ADUO framework was created to help engine suppliers close the performance gap, and Mercedes, Ferrari, Audi and Honda are eligible to develop under it, while Red Bull was the best engine performer in the first period and cannot use the catch-up concessions.
Ferrari is preparing to follow with its first ADUO-influenced engine upgrade at the Austrian Grand Prix in Spielberg, using its first token on a revised internal combustion engine. Ferrari power unit director Enrico Gualtieri said the update is relatively minor and worth less than 10 horsepower, adding that it will not change the competitive order on its own. Ferrari has described the package as part of a longer development program aimed at improving its engine performance and reducing the gap to Mercedes.
A more substantial Ferrari step is already mapped out for after the summer break, with a new or redesigned turbocharger expected to form part of the next package. Ferrari views that later update as part of its incremental approach to power unit development, with the broader target of closing the performance gap to Mercedes and Red Bull. Gualtieri said the factory is focused on getting improvements from the factory to the track as quickly as possible.
