Audi's "very, very long list" of issues: the team is navigating an unprecedented reliability crisis

Audi's first official Formula 1 test proved to be a sobering introduction to motorsport's most demanding discipline. After completing just 240 laps across three permitted test days at the Circuit de Barcelona-Catalunya, the newly arrived German manufacturer discovered that transitioning from being a customer team to a full-fledged engine producer would demand far more than anticipated.

Gabriel Bortoleto's opening day proved particularly troubling. The Brazilian rookie, fresh off an impressive debut season, managed only 27 laps before a technical issue forced Audi to abandon its morning session entirely. When the team returned to action on Wednesday, matters initially worsened—Nico Hulkenberg ground to a halt just five laps into the day with a suspected hydraulic problem, threatening to derail what was shaping into a difficult week.

The magnitude of the challenge

Project leader Mattia Binotto's assessment of Audi's position proved the most damning verdict of the test. The Ferrari veteran, with decades of experience navigating Formula 1's technical complexities, declared it the largest list of issues he had encountered in his entire career.

"It's a lot of work for the entire team, it's a lot of work for the drivers, for the engineers back at home, fixing all the problems: design, operational, whatever we have seen" Binotto explained. "So it's really for us, no stones [left] unturned. All the details need to be managed and need to be fixed, so we've got a very long list. A very, very long list. I've never seen such a long list."

The issues ranged across multiple systems—gearbox complications, hydraulic leaks, and power unit teething troubles—each representing a distinct engineering mountain for the team to scale before Melbourne's season opener.

A midweek turning point

Yet Wednesday afternoon proved pivotal. After resolving the hydraulic issue, Audi returned to the track with renewed determination. Hulkenberg completed 68 laps in the afternoon session, demonstrating that once the team identified problems, solutions were within reach. This positive momentum carried into Friday, where Audi produced its strongest performance of the week—145 laps shared between both drivers, representing more than 60% of the team's entire three-day total.

"It was certainly one of our better days, or our best day here this week" Hulkenberg reflected. "More than 140 laps, some good mileage for the car and for all the components. And on the power unit side, it's important for us to get that sort of mileage."

The data disadvantage

However, Audi faces an inherent structural disadvantage that no amount of engineering wizardry can immediately overcome. With no customer teams running its power unit, the German manufacturer completed just 240 laps across the entire Barcelona test—dwarfed by Mercedes (1,132 laps), Ferrari (989 laps), and even Red Bull Powertrains (622 laps). This data deficit means Audi enters the 2026 season significantly behind in understanding how to extract maximum performance from the revolutionary new regulations.

"For a first timer's new power unit, of course we knew it's going to be bumpy. There's going to be issues, but we work through them, and we'll continue to do so," Hulkenberg acknowledged.

Binotto's silver lining

Despite the challenging Barcelona assessment, Binotto maintained strategic optimism about Audi's trajectory. He stressed that all identified issues were "small, not dramatic" and crucially, "fixable". The real value of Barcelona, from Audi's perspective, lay not in raw pace or lap counts, but in the diagnostic blueprint it provided.

"The more we run, the more we learn and I think we are really at that stage," Binotto stated. "Reliability equals knowledge and, at this point of a new rules cycle, knowledge is power."

The road to Bahrain

As Audi prepares for next month's Bahrain pre-season tests, the team's priority remains crystal clear: convert the Barcelona learnings into sustained reliability and mileage accumulation. Only once the R26 demonstrates consistent operational stability can performance development truly accelerate.

For a manufacturer making its grand entrance to Formula 1 with its own power unit, the 2026 season will ultimately be defined not by early pace, but by how decisively Audi can transform its "very, very long list" of problems into a checklist of solved challenges.
