Red Bull confirms no immediate power unit upgrade despite ADUO allowance

Red Bull Racing has confirmed it will not immediately pursue a power unit upgrade permitted under a new F1 concession rule, choosing instead to focus its development resources on fixing chassis issues. Team principal Laurent Mekies stated that while their new Red Bull Ford Powertrains (RBPT) unit is closer to the front than expected, the priority is solving the car's underlying performance problems before considering engine updates later in the season.

Why it matters:

This strategic decision highlights a significant shift in Red Bull's internal challenges. For the first time in the ground-effect era, the team's primary performance deficit appears to stem from its chassis, not its power unit. By deferring a permitted engine upgrade, Red Bull is betting that aerodynamic and mechanical fixes will yield greater lap time gains than chasing marginal power unit improvements, a calculated risk that defines their 2025 recovery strategy.

The details:

• ADUO Rule Explained: The Additional Development and Upgrade Opportunities (ADUO) regulation allows teams whose power units are measured to be more than 2% behind the benchmark to introduce a performance upgrade. Red Bull is eligible under this rule.
• Strategic Deferral: Mekies confirmed that while the team has the right to upgrade, they are "probably not" ready to do so immediately. The need to manage the allocation of four power units per season forces teams to "pick your moment" for substantial upgrades.
• Power Unit Performance: Contrary to widespread pre-season fears, Red Bull's internal data shows its new RBPT power unit is only about three-tenths of a second per lap behind the leading Mercedes unit. Mekies called this a pleasant surprise, stating the performance "has clearly exceeded expectations" and that "the ghost of the power unit has disappeared."
• Primary Focus: The team acknowledges its current performance gap is due to chassis and car balance issues. Mekies emphasized that fixing the car is the known and immediate priority: "We need to get these tenths back. We need to fix what we need to fix with the car. This we know how to do it."

What's next:

Red Bull's development path is now clearly mapped for the coming months.

• The team will focus on bringing chassis and aerodynamic updates to address its current performance deficit, with Mekies noting improvements will come after the Miami Grand Prix.
• A power unit upgrade under the ADUO rule is more likely in the second half of the 2025 season, grouped with other developments to create a "sizeable enough" performance step.
• This approach also aligns with the broader 2027 engine regulation window, allowing Red Bull to strategically time its technical investments. The immediate goal is to stabilize the car's performance, believing that chassis solutions will provide the fastest route back to consistent podium contention.
