Red Bull Racing encountered engine and balance challenges during the first test of a significant upgrade package at the 2026 Austrian Grand Prix. The team introduced changes aimed at improving the car’s performance, but initial running revealed some inconsistencies that affected driver confidence and car handling.
The upgrade package featured a revised floor, new sidepods, and efforts to reduce overall weight. However, both Max Verstappen and Isack Hadjar experienced engine-related issues in Turn 3, where the power unit lost revolutions at the apex. This caused a “hit-and-miss” throttle response and wheelspin on corner exit, making traction unpredictable. Verstappen described the grip as poor and non-linear, complicating his ability to manage the car’s behaviour through the corner.
Technical director Pierre Wache confirmed that the root cause of these problems lies in engine management, which the team aims to resolve before qualifying. Similar issues have been affecting Red Bull’s sister team, Racing Bulls, for some time, but this marked the first occasion they impacted the senior Red Bull Racing squad. The extensive upgrade package altered the car’s characteristics and balance, requiring further setup work and adaptation throughout the practice sessions.
Hadjar noted that while the car currently feels off balance, it is easier to drive than before, indicating potential gains once the setup is optimised. Team principal Laurent Mekies expressed hope that the upgrade could reduce Red Bull’s deficit to rivals from around 0.4-0.5 seconds to approximately 0.2-0.3 seconds. Wache also highlighted that the upgrade represents progress in terms of weight reduction and downforce, with a clearer understanding expected after overnight analysis and the following practice session.
These developments underline the complexities involved in integrating major upgrades mid-season, especially when changes affect both aerodynamic and mechanical aspects of the car. Red Bull’s focus remains on resolving the engine management issue promptly to maximise the benefits of the new package during qualifying and the race.
While the initial test revealed some challenges, the team’s approach reflects a measured effort to improve performance incrementally. The experience gained during the Austrian Grand Prix practice sessions will inform further adjustments as Red Bull seeks to enhance the car’s balance and reliability in the coming events.
