George Russell admits Mercedes still needs time to “fine-tune” problematic upgrade package

George Russell has admitted that Mercedes still requires time to fine-tune the problematic aerodynamic upgrade package introduced earlier this month. Speaking ahead of the United States Grand Prix at Circuit of the Americas, Russell revealed that the parts brought in Malaysia did not perform as expected. However, following data collection in Singapore, the team remains confident that the upgrade package is the right development direction.

Mercedes faces increasing pressure from Red Bull, McLaren, and Ferrari in both championship battles, with Max Verstappen winning recent races. Russell noted that having three full practice sessions under Austin's traditional weekend format will provide a crucial opportunity to optimize the car's setup window.
