Max Verstappen provided clarity on the engine issues that affected Red Bull Racing during the qualifying session at the Azerbaijan Grand Prix in Baku. The problem, which started in Q1, impacted his performance throughout the session and ultimately influenced his starting position.
Initially, the issue was thought to be related to the electrical deployment system of the power unit. However, Verstappen explained that the root cause was actually with the internal combustion engine (ICE). This malfunction led to a loss of around half a second compared to his teammate and worsened as qualifying progressed. The engine misfired and caused confusion within the system, including problems with battery charging and energy recovery, which are critical for performance in the current hybrid Formula 1® power units.
The ICE problem resulted in reduced top speed and forced Verstappen to abort a flying lap during qualifying. This not only affected his lap time but also caused a loss of tyre temperature, further compromising his pace. Additionally, a yellow flag triggered by Lando Norris during Verstappen’s final lap added to the difficulties, preventing him from improving his time. Verstappen eventually qualified eighth but suggested that without the engine troubles, he might have been closer to the front row.
Red Bull Racing is investigating the issue and considering replacing the internal combustion engine. Importantly, Verstappen will not face a grid penalty for this engine change at Baku, although he confirmed that a penalty for engine changes is expected later in the season. The unusual behaviour of the power unit, particularly the battery usage and energy recovery, resembled challenges previously seen in Honda-powered cars, highlighting the complexity of the hybrid systems.
The qualifying session also saw other teams affected by incidents, such as McLaren dealing with pit stop timing and the yellow flag caused by Norris. Verstappen’s teammate, while not directly involved in the engine issue, set a benchmark that Verstappen was unable to match due to his car’s technical difficulties.
Verstappen’s comments shed light on the technical challenges faced by Red Bull Racing during this phase of the Azerbaijan Grand Prix weekend. The situation underlined how critical the reliability and integration of the internal combustion engine remain, even as hybrid systems grow more complex in Formula 1®. The team’s focus remains on resolving the issue to restore full performance without incurring penalties that could affect their race strategy in future events.
