Audi will hand Paul Aron another run in Formula 1 machinery this weekend at the Austrian Grand Prix, with the Alpine reserve drafted in to drive Gabriel Bortoleto’s R26 in Friday’s opening practice.
On paper, it’s a simple box-ticking exercise. In reality, it’s starting to look like a pattern — and one that raises a few eyebrows around the paddock given Audi still hasn’t named a formal reserve of its own.
Aron’s involvement with the project isn’t new. The Estonian was the subject of a slightly odd “loan” arrangement last year when Sauber, in its final season before the full Audi rebrand, took the opportunity to run him across several FP1s. He first appeared in Britain and Hungary, then turned up again for Alpine in Italy, Mexico and Abu Dhabi as teams rotated rookies through the mandatory sessions.
That storyline has simply carried into 2026. Aron already got seat time earlier this month in Barcelona, deputising for Nico Hulkenberg in FP1 — and he made it count. Sixth on the timesheets doesn’t win anyone a trophy on a Friday morning, but lapping 0.9s quicker than Bortoleto in the same session is the sort of thing engineers notice even when they insist they don’t.
This weekend he’ll swap sides of the garage again, taking Bortoleto’s car at the Red Bull Ring. It means both Audi race drivers will have sat out one FP1 apiece once Austria is done, leaving each still needing to miss one more session across the remaining 14 rounds to satisfy the regulation that requires teams to run a rookie — defined as someone with no more than two grand prix starts — four times per season.
In other words, there are more of these interruptions coming, and Audi is choosing to manage them without the safety net every other team keeps within arm’s reach.
Audi is currently the only outfit on the 2026 grid without an official reserve driver. That’s become more conspicuous now the team is a full works operation rather than a rebranded Sauber with borrowed muscle. In 2025, Sauber leaned on a Ferrari sharing agreement that left it covered in an emergency by Antonio Giovinazzi and Zhou Guanyu — the latter now on Cadillac’s books as a reserve. Audi has since cut ties with Ferrari, yet still hasn’t installed a dedicated understudy behind Hulkenberg and Bortoleto.
So Aron continues to do the job — useful, available, and already familiar with the environment. From Audi’s perspective it’s an efficient solution: compliance with the rookie rule, a chance to gather additional data with a fresh set of eyes, and a low-risk way to benchmark internal references. From the drivers’ perspective, it’s less comfortable. Practice time is precious in 2026, with the learning curve steeper and the margins tighter, and neither Hulkenberg nor Bortoleto is driving a car so dominant that they can afford to shrug off lost laps.
That matters for Bortoleto in particular. Audi’s start to its debut season has been encouraging without being headline-grabbing: two points on the board, regular weekends hovering around the edge of the top 10, and an overall impression of a team that’s more “in the fight” than many expected so early. But the hard numbers are still modest, and Bortoleto’s ninth place in Australia remains Audi’s best result of the campaign.
In that context, giving up an FP1 session isn’t just a regulation annoyance — it’s a small dent in rhythm, and a reminder that Audi is still building its operational foundations while trying to race.
There is at least a long-term logic to the way Audi is going about it. The team has launched a junior programme this year, with 17-year-old British F3 driver Freddie Slater announced as its first recruit. Nineteen-year-old Austrian Emma Felbermayr, competing in F1 Academy, is also part of Audi’s junior set-up. That points to an intention to create a proper ladder under the factory banner — but it’s still a separate thing from having an experienced reserve ready to step in at a moment’s notice.
For now, Austria becomes Aron’s next shop-window, and Audi’s next reminder that its 2026 project is being run with a slightly different set of assumptions. If he delivers another tidy, quick session, he’ll only reinforce the sense that he’s becoming Audi’s de facto stand-in — even if the team doesn’t want to put that title on paper.
