WEEKEND WARM-UP: Mercedes look to maintain winning ways as upgrades arrive for Miami

F1 makes its return with Miami hosting the fourth round of the season this weekend. Kimi Antonelli is looking for his third straight win, but his team mate and one or two others might have something to say about that.

With F1 having had a longer than expected break from racing since Japan, intrigue is high in the paddock over who might have brought the best upgrade package to the USA. Every team is running something but it remains to be seen if the pecking order will dramatically change.

Mercedes are expected to be quick, with Antonelli and George Russell likely to resume their intra-team rivalry as they battle for the win, but the Italian teenager is wary of the opposition.

Fernando Alonso has added to speculation that he may call time on his F1 career after this season, while Nico Hulkenberg and Gabriel Bortoletto give their take on Allan McNish becoming Audi's Racing Director.

Max Verstappen offered his view on long-time race engineer Gianpiero Lambiase leaving Red Bull for McLaren in 2028, and Cadillac and Haas will be looking for strong results on home soil this weekend.
