Fernando Alonso has expressed concerns that Aston Martin is losing ground in the ongoing battle of energy management in Formula 1, which he refers to as the 'battery world championship.'

Alonso noted that while Aston Martin performs well during the initial laps of races, they tend to fall behind as the race progresses, particularly in terms of battery performance and energy deployment.

He explained that the team's current energy recovery systems and battery management strategies are not as effective as those of their rivals, which puts them at a disadvantage in the long run.

Alonso emphasized that the 'battery world championship' is a critical aspect of modern F1 racing, where teams compete not just on speed but also on how efficiently they manage their energy resources throughout the race.

He highlighted that this challenge is especially significant given the new regulations and technological advancements that have increased the importance of battery performance in determining race outcomes.

Despite these struggles, Alonso remains optimistic about the team's potential to improve their energy management systems and close the gap with leading competitors.

He also pointed out that the development of better battery technology and strategic energy deployment could be key factors in turning the tide in Aston Martin's favor in future races.

Overall, Alonso's comments shed light on the evolving technical challenges in Formula 1, where innovations in battery and energy systems are becoming as crucial as aerodynamics and chassis design.
