Audi has confirmed that it will introduce no further significant Formula 1 power-unit upgrades in 2026, having already used the first development step permitted under the ADUO framework. The German manufacturer will instead concentrate its personnel, resources and budget on its 2027 project as it seeks to recover from a more difficult debut season than anticipated.
Audi entered Formula 1 after acquiring the Sauber operation and chose to build its own engines under the supervision of Mattia Binotto. The new regulations appeared to offer a major opportunity for the automotive giant, but both the on-track results and the FIA’s power-unit performance hierarchy have highlighted the scale of the challenge.
The engine powering Audi’s cars remains well behind its rivals, particularly the impressive Ford-Red Bull Powertrains unit. That project is also competing in Formula 1 for the first time in 2026 but has already established itself as the performance benchmark.
Despite its difficult opening campaign, Audi reached the summer break having made enough progress to move ahead of Williams after Nico Hülkenberg’s first points of 2026. Its latest position relative to the other teams can be followed in the Formula 1 constructor standings.
Audi power-unit upgrade improved drivability
The update introduced between the Spanish and Austrian Grands Prix was not primarily intended to increase the engine’s maximum power. Audi instead focused on improving drivability, particularly through slow corners where the car had previously been at its weakest.
Allan McNish confirmed the purpose of the upgrade during the Hungarian Grand Prix weekend.
“We introduced an update in Austria that helped us a great deal, especially in the slow corners, where we were weaker,” Allan McNish explained. “We adapted certain aspects and managed to improve drivability. These are characteristics that really make a difference in low-speed corners.”
A more predictable and manageable car allows the drivers to exploit the available performance more effectively, even when the power unit still lacks the outright output of the leading manufacturers.
Audi accepts that its F1 engine power deficit remains
Despite the progress delivered by the first upgrade, Audi recognises that it remains some distance behind the strongest manufacturers in terms of absolute power.
Mattia Binotto had already explained in recent months that the deficit to the benchmark power units would not be eliminated completely before 2028. Audi hopes that, by then, it will have a car capable of fighting consistently for victories.
The ultimate objective remains winning the Formula 1 World Championship in 2030, but the German manufacturer accepts that its rise towards the front of the grid will necessarily be gradual.
No second Audi ADUO power-unit upgrade in 2026
The regulations permit two homologations within the ADUO system, creating the possibility that Audi could introduce a second upgrade during the latter part of the season. The FIA’s ADUO development mechanism was designed to give underperforming power-unit manufacturers additional opportunities to reduce their deficits.
However, Audi has now ruled out using its second opportunity during the 2026 campaign.
“It will arrive next year,” Allan McNish replied when asked about the next update.
His concise answer confirmed that no further hardware development is planned for the Audi power unit this season. The focus has already shifted towards preparing a more competitive specification for 2027.
Budget cap influences Audi’s power-unit decision
The decision is based not only on technical considerations but also on a carefully defined financial strategy. Audi must decide when each development package will provide the greatest long-term value without exhausting the resources available for future seasons.
“Everyone has to manage the compromise over when to introduce upgrades, both to the chassis and the power unit, and where to invest the budget,” Allan McNish said. “You cannot spend everything immediately, otherwise you have nothing left for the future. Expectations have to be managed carefully, not just for one season but across several years.”
ADUO allows manufacturers to use additional development funds, but the overall financial impact of another significant upgrade would evidently have required expenditure beyond the budget Audi had allocated for the programme.
Audi will continue developing its 2026 chassis
Freezing significant power-unit hardware development does not mean Audi will stop improving its 2026 car entirely. Aerodynamic and chassis upgrades will continue during the second half of the championship, even though the engine specification will remain essentially unchanged.
“This year, we have also managed to improve performance through the power unit by maximising some of its systems,” Allan McNish explained. “However, the work carried out on the chassis has been equally important.”
“We will continue developing that part of the car during the second half of the season, while the power-unit work concerns 2027. It involves hardware, and that is not something you can change quickly.”
