Lando Norris and Max Verstappen expressed frustration during the Japanese Grand Prix, criticizing the F1 power unit's unpredictable behavior.
Norris described the racing as "yo-yoing" because his battery deploys uncontrollably when trying to overtake. He felt powerless behind the wheel, noting that he had to lift to avoid crashing but then couldn't re-apply throttle without the battery deploying again, leaving him with no energy to defend. Verstappen echoed these concerns, agreeing that the Suzuka layout exposed the difficulty of timing an overtake due to the power unit issues.
