Audi has conceded that its repeated slow race starts are rooted in power unit limits and will not be solved soon. The issue was clear again at Suzuka, where Nico Hülkenberg and Gabriel Bortoleto lost ground off the line and never recovered. The Audi pair had qualified well at the Japanese Grand Prix, with Bortoleto in P8 and Hülkenberg in P13, but both slipped back at the start and finished outside the points.
Team figures say the pattern is now a core weakness. Bortoleto and Hülkenberg have both highlighted starts as a major problem this season. Acting team principal Mattia Binotto has aligned with that view and put race launches near the top of the to-do list. He and the drivers also warned that there is no simple or overnight fix.
Audi links the deficit to the design of its power unit. The current architecture uses a relatively large turbo compressor. That choice brings greater turbo inertia and slower boost arrival. When the driver releases the clutch, the internal combustion engine does not reach target torque as fast as rivals. The team must lean harder on electrical deployment to fill the gap while the turbo spools. That means using a limited store of harvested energy to cover shortfalls at the very moment the car needs a sharp hit of torque. The outcome is a softer launch and a higher risk of losing places in the first 100 meters.
This dependency also shapes how Audi manages the opening phase of the race. The system must balance turbo speed-up with electric delivery without breaching control limits. Any misstep reduces traction and throttle response at the launch. Audi says this is not a software switch or a clutch tweak that will unlock easy gains. The behavior comes from hardware choices that define how fast the power unit can deliver boost and how much the electrical system must contribute to match that target.
The FIA’s ADUO catch-up framework offers some relief, but not on the timeline of a few race weekends. The regime allows certain mid-season concessions after evaluation. That process takes time, and any approved change still needs design, manufacturing, and validation. Major hardware like a turbo compressor affects packaging, cooling, and controls. Those parts carry long lead times before they reach the car. Audi expects that reality to limit any immediate step forward from ADUO pathways.
The setbacks at Suzuka underlined how these factors play out in results. Bortoleto’s P8 on Saturday showed the car’s one-lap pace. Hülkenberg’s P13 was in the mix for points with a clean launch and strong first lap. Both drivers lost positions right away, which left them fighting in traffic and off the planned strategy. The team pointed to the start phase as the trigger for the slide, rather than tire wear or car balance in clean air.
Inside the garage, the priority is to tighten procedures and refine how the energy system supports the launch. That means finding the best trade between electrical push and turbo spooling within the current hardware limits. The broader fix sits in the next power unit steps, where design choices can cut turbo inertia and improve boost response. Those changes are part of Audi’s longer program.
Audi has framed its recovery as a multi-year plan. The team has set 2030 as the target to fight for the championship. Leaders stress patience and adherence to the roadmap, not short-term miracles. The group will keep working on starts while the engine program moves through its planned phases. Gains from the ADUO route will come when the process and lead times allow. For now, Audi sees the start deficit as a symptom of its current architecture and a problem that will ease only as the next development cycles reach the track.
