F1 Results Today: Kimi Antonelli suffers issue as Mercedes face setback at Miami GP

F1 teams had an extra 30 minutes in practice for the Miami Grand Prix, with an unusual 90-minute session kicking off track action on Friday.

With an extended gap between races after the cancellation of the Saudi Arabian and Bahrain Grands Prix, and only one practice session due to the weekend hosting a sprint race, teams were given a little extra time to dial in their various updates (well, not so much for the update-free Aston Martins).

The session itself was relatively uneventful, but a couple of cracks started to appear in Mercedes' silver armour late on when a power unit issue ended Kimi Antonelli's time on track early, before he could get a qualifying simulation run on soft tyres.

His team-mate George Russell wasn't exactly the dominant force that might've been expected either, setting just the sixth fastest time of the session, more than three quarters of a second down on the leading time of Charles Leclerc.

The other note emerging from the hour and a half of running was the reveal of Red Bull's new 'Macarena' rear wing, which flips somewhat more dramatically than Ferrari's equivalent.
