What happened: Red Bull is leading internal combustion engine performance early in the 2026 Formula 1 season but is struggling with the electrical components of its power unit. The team anticipates these energy management issues will continue at power-starved circuits like Spa following a difficult weekend at Silverstone.

Why it matters: The electrical deficit presents a significant technical hurdle for the constructor under the new engine regulations. An inability to maximize energy deployment compromises pace on high-speed tracks, compounding other recent issues such as the investigation into rear wing failures.

What to watch: Engineers will attempt to optimize the system's energy deployment to mitigate lap time losses at the upcoming Belgian Grand Prix.
