An uphill battle
To some degree, Audi can be satisfied they avoided certain pitfalls in the build-up to testing. Although their 240 lap tally is nowhere near what the likes of Mercedes accomplished, they still leave Barcelona with respectable mileage.
Moreover, their engine – whilst experiencing a few hiccups – still completed the equivalent of several race distances. This provides the engineers back at Neuberg with plenty of data to go through and analyse.
However, there is still plenty of room for improvement. Aside from the Honda engine (which had limited track time due to Aston Martin’s delays) the Audi power unit completed the fewest laps.
Unlike Honda, the German manufacturer does not have over a decade of experience in Formula 1 to draw from. Moreover, Audi do not have the luxury of a customer team running their power units and helping collect more data.
This gives established names like Mercedes and Ferrari another advantage. Even Red Bull, who also debut new engines, enjoy the benefit of VCARB gathering data with their power units.
More broadly, there is the question of whether Audi used the 2026 sustainable fuels in the Barcelona shakedown. As recently analysed LWOS, the interaction between the new carbon-neutral fuels and 2026 engines could be the biggest cause of reliability woes this season.
Aside from the complexity of the power units themselves, the unique fuels used by the teams (based on how their suppliers developed biofuels to meet the FIA’s standards) require immensely sophisticated chemical reactions to work effectively with the 2026 powertrains.
If Audi used the sustainable fuels in Barcelona, they could actually have a better understanding of this area than their rivals. However, if they opted against this, Audi could encounter another set of problems when testing commences in Bahrain.
Reliability has been mentioned as a top priority at the German outfit for several months. Binotto knows better than most about the importance of getting the foundations right with an F1 power unit.
Only with a durable engine can Audi begin focusing on more performance-related updates.
