Audi's first season as a full works Formula 1 team has produced steady, unglamorous progress: points in each of the last three rounds, and a power unit that is noticeably better to drive than the one the team started the year with. What it will not produce is another engine step. Racing director Allan McNish confirmed to Motorsport.com that Audi has spent what it intends to spend on the powertrain in 2026.
Asked when the next powertrain update would arrive, McNish's answer was one word long: "It'll be next year."
The reasoning is financial rather than technical. Under the cost cap, every euro committed to an engine upgrade in August is a euro unavailable for the car in October.
"Everybody has got this trade-off between when you're bringing upgrades - chassis and PU - and also where you spend your money," McNish said. "Because you can't spend everything at one time, because then you don't have anything to fight with later. So it's got to be a managed expectation, and not just over one season, but multiple seasons as well."
Audi did use its ADUO allocation early, bringing a small package to Barcelona. McNish framed that as the cheap win, with the expensive one deliberately held back.
"We brought something in Barcelona straight away, which was some small adaption, and that worked well, that helped us on our way," he said. "And then I would say the bigger parts are for 2027. So we will not see anything big on the power unit until then. [...] It's more hardware than anything, and that's not a quick thing to change."
What the Barcelona update actually bought is best explained by the driver. Nico Hulkenberg, speaking at Spa-Francorchamps, described a gain that does not show up as a headline power figure at all.
"It is about what you request on the pedal, but how the PU responds, how the torque delivery is. Does it surge, is it consistent, is it smooth? It is very fine stuff," Hulkenberg said. "We can talk about it, but you need to have experience to feel it. It happens in a blink of an eye, less than a tenth on a corner exit. But with a car on the limit, over the limit, all these things matter a lot."
He went further on why small numbers matter more than they sound: "If you then have driveability issues on top of that, it is like trying to hit a curveball."
Audi team boss Mattia Binotto has been more pointed about the mechanism that granted those upgrades in the first place. The ADUO system measures a manufacturer's deficit through on-track performance, and Binotto argues that is the wrong yardstick when a team's advantage might be coming from somewhere other than the engine.
"In my opinion, the limit has been that it has exclusively measured performance on the track. A car with an overall advantage can afford not to fully exploit the potential of its power unit," Binotto said. "It's possible, for example, that Mercedes had an engine with superior potential but had no need to push it to the limit because it already had an advantage thanks to the car."
Binotto was careful to separate the rule from the regulator: "On the results, I'm not questioning the work done by the FIA. They have all the tools and data necessary to make their assessments."
His objection is to drift rather than to error. "When it was first discussed, the concept was that of a sort of safety net," he said of ADUO. "This wasn't the original intent [...] the goal was to help those who were actually falling behind, not to create situations in which the true potential of a power unit might be difficult to assess."
Seen from outside, the discipline reads as strength. Guenther Steiner, discussing the 2028 driver market, cited Audi's trajectory as the reason drivers are circling.
"There's a lot of interest from drivers to go to Audi for 2028," the former Haas team principal said. "That's quite an interesting place because they're making good progress. It seems to be on track, what they are doing."
So the same set of facts supports two readings. McNish's is that a team building for five years should not blow its cap position in year one. Binotto's is that the framework meant to protect newcomers may be rewarding the wrong people. Both can be true, and Audi's midfield points finishes are, for now, the only evidence either way.
