The Audi R26 has been struggling on the straights, with the team led by Mattia Binotto identifying performance gaps in the Audi power unit, designed from scratch by engineers in Ingolstadt. In Hinwil, the team has a recovery plan utilizing the ADUO system, but results are not expected in the short term.
Audi entered Formula 1 in a fully fledged way, building its power unit entirely in-house due to the new technical regulations. This has forced the German team to develop both the internal combustion engine and the electric components of the hybrid system from the ground up.
Much like the 2014 season, when hybrid power units were first introduced and many teams struggled, 2026 presents similar challenges. It is not just the internal combustion engine but the energy derived solely from the MGU-K—after the MGU-H ban—that must be managed during the lap for attacking, defending, or performance, as well as recovering the energy efficiently.
The R26, which debuted during the Barcelona shakedown in January, initially appeared conventional, especially around the sidepods, almost timid in design. However, within days, the car showed a notably bolder aerodynamic approach in the same area. Narrow, sculpted sidepods with vertical air intakes revealed advanced wind tunnel research. The first races of the season brought 2 points to the team, initially led by Jonathan Wheatley and now managed by Mattia Binotto. But these results don’t tell the full story: the R26 has far more potential than the numbers suggest.
Yet, several critical weaknesses emerged, limiting Nico Hulkenberg and Gabriel Bortoleto’s ability to score more points up to the Japanese Grand Prix, the third round of the 2026 F1 season. The R26 has proven to be a solid car, competitive enough to fight for the mid-field, but the deficits are noticeable—particularly for a team that had to develop a power unit entirely from scratch. The German car lacks performance compared to the front-running Mercedes and Ferrari entries.
These power units are not just powering the leading teams but also customer teams McLaren (third), Haas (fourth), Alpine (fifth), Williams (ninth), and Cadillac (tenth). Audi currently sits eighth, behind even Red Bull and Racing Bulls, which run Red Bull-Ford engines.
For this reason, Hinwil is waiting for the opportunity to fully implement the ADUO system. Initial power unit checks are planned for the Monaco Grand Prix, but it will take months before the full benefits of this FIA-designed system, aimed at helping underperforming engine manufacturers, are realized.
“Engine development takes a long time,” said Mattia Binotto, Audi team principal, after the Japanese Grand Prix. “We’ve assessed that much of the gap we have to the top teams comes from the power unit, which is not unexpected. We knew this would be our biggest challenge. And we have a plan to recover. But engine development, especially with some new concepts, can take longer.”
“It’s no coincidence that we set 2030 as our target. We know it will take time. Right now, we also need patience. We are ambitious and would like to see the problems solved in a couple of races, but sometimes it doesn’t happen that fast. We need to understand exactly where we are as a team, stick to our plans, and work step by step. Miracles aren’t possible—we’re here to have solid plans to solve problems and improve in the future. And I believe that is achievable.”
Binotto explained the R26’s lack of straight-line speed in more detail, attributing it to the power unit. “Much of the deficit comes from the engine. When you don’t have straight-line speed, you can use energy to defend. But once the battery is depleted, there’s very little left. We need to analyze the data carefully and avoid jumping to conclusions.”
“Yes, there’s an aspect related to how we manage energy. Straight-line speed is currently not our strength. Using energy inefficiently exposes us to overtakes. This is part of our learning process in the first races. We need to review the data with the driver and understand how to mitigate these situations, not just fix them, and then see what can be done in the near future.”
The rear wing helps but isn’t a complete solution
This season, the FIA has relaxed rules on rear wing usage at certain track sections, giving designers more aerodynamic freedom and reducing drag on straights. This allows higher top speeds and lower energy consumption. Audi, along with Ferrari and Alpine, has been among the most inventive teams with movable rear wing flaps. In the configuration debuted at the second Bahrain pre-season test, the wing actuator moves the second element downward while the first remains static.
This system also offers aerodynamic benefits during transitions—the opening and closing of the wing. When the flap closes at the end of a straight, speeds are still high, and the transition should improve braking stability. However, aerodynamically, it’s not sufficient to compensate for the lack of power from the German V6 combined with the KERS system.
Therefore, Audi must continue improving the R26 mechanically and aerodynamically before the ADUO power unit upgrade can be fully implemented. According to Binotto, the concepts are already ready, but regulatory timelines and manufacturing constraints mean this is not an overnight fix. Progress will take months, as is the case for all teams.
