5 storylines we're excited about ahead of the Miami GP

F1 returns to action with the Miami Grand Prix, the fourth round of the 2026 season and the second Sprint weekend of the year. Following a four-race hiatus, teams arrive in the United States with significant upgrade packages, with McLaren Team Principal Andrea Stella suggesting that many competitors, including his own team, will be debuting 'entirely new' cars to address the performance potential unlocked by this year's technical regulations. Kimi Antonelli enters the weekend holding a nine-point lead in the championship over teammate George Russell. Following his breakout performance at this circuit last year, the young Mercedes driver looks to continue his dominant form. Meanwhile, the FIA has implemented technical adjustments following collaborative discussions with stakeholders, aimed at improving qualifying performance and race-day safety, which will be tested under race conditions for the first time this weekend in Miami. This event also marks a major milestone for Cadillac, competing in their first home race. With Haas also looking to capitalize on their strong start to the season, the American teams are poised for a high-stakes weekend. Additionally, the F2 championship makes history by racing on the North American continent for the first time, adding further excitement as the grid prepares for a 90-minute practice session to adjust to the new regulations before the Sprint action begins.
