McLaren's latest upgrade package has been described as "a pleasant surprise" by Motorsport's Stuart Codling, but questions remain over whether the team will retain the new components for the Brazilian Grand Prix.
The upgrade, introduced at the previous race, showed promising performance gains during practice sessions. However, the team is evaluating its reliability and suitability for the Interlagos circuit's unique demands.
McLaren has not yet confirmed if the upgrade will stay on the car for the remainder of the weekend. A decision is expected before qualifying.
