What happened: Red Bull encountered a power-unit issue during qualifying at Silverstone and lacked the pace to challenge at the front. The setback followed a second-place finish in Austria one week earlier.

Why it matters: The sharp swing leaves Red Bull facing a difficult British Grand Prix from outside the leading grid positions. High-speed performance and power delivery could limit its ability to recover during the race.

What to watch: Red Bull must decide whether to retain the current power unit or make changes that could affect its starting position.
