Mercedes confirm car plans for US GP after unusual Singapore split

Mercedes have confirmed Kimi Antonelli and George Russell will both run their latest-specification car at this weekend's United States Grand Prix.

After a problematic debut for the team's long-awaited new aerodynamic package on F1's return to Malaysia earlier this month, only Antonelli ran the upgrades last time out in Singapore while Russell, who carried a grid penalty for the main race into that weekend, reverting to the pre-Sepang version so the team could compare the two on track.
