Hamilton cautious on US GP prospects amid out-of-sync upgrade

Lewis Hamilton has expressed cautious optimism about Mercedes' prospects for this weekend's US Grand Prix, highlighting how the team’s strategic approach to development has been a factor behind its recent performance issues.

Unlike their rivals, who have introduced new parts at various points throughout the season, Mercedes has opted for a more concentrated upgrade schedule.

This has meant that they have been running older specifications at certain races, potentially hindering their competitiveness.
