The 2026 Formula 1 calendar gets back on track this week after an enforced hiatus, with the Miami Grand Prix being billed as the de‑facto launch of a "new championship". This marks the first time since the Japanese Grand Prix on 29 March that all teams will once again share the circuit, gathering at the Miami International Autodrome on Friday after a five‑week lull caused by the cancellation of the Bahrain and Saudi Arabian rounds in the original 24‑race schedule. Miami now serves as the fourth race weekend of the year and the second Sprint event, but the month‑long break has given every outfit a rare window to develop their brand‑new 2026 cars.
Since Mercedes’ rookie Kimi Antonelli seized the championship lead with a win at Suzuka, teams have been hard at work in their factories, meaning the return to competition is likely to look different from the opening three meetings. Ferrari team principal Frédéric Vasseur, whose squad had been the closest challengers to Mercedes before the pause, described the upcoming weekend as essentially another start to the season.
"Everyone will bring fresh upgrades to Miami," Vasseur told Sky Sports Italy, adding that teams will have had time to fine‑tune software, which is why he believes a "new championship" is about to begin. Mercedes boss Toto Wolff echoed that sentiment, noting that his Silver Arrows have claimed victory in all three races and the Sprint so far, but that the break gives rivals a chance to catch up.
"Teams have learned, drivers are starting to learn how to optimise these systems to their benefit and we've seen that first indication in Japan that looked like a home run in the first two races but isn’t the case and we’ve always won," Wolff said. "Miami is going to be for me also a restart. How are the upgrades going to work that people are bringing? How have we optimised all the other systems?
It’s going to be exciting." The original plan had seen the series race in Bahrain on 12 April and then head to Saudi Arabia a week later, but both events were called off on safety grounds amid the Middle‑East conflict. With no viable alternatives and no other April dates on the calendar, the season suffered an unscheduled five‑week gap – the longest in‑season pause since the opening two rounds of the 1999 campaign, when discounting the usual summer and winter shutdowns.
Unlike the mandated factory closures during the August summer break and the off‑season winter shutdown, the eleven teams were free to continue development behind closed doors throughout April. The $215 million (£159 million) budget cap and aerodynamic testing restrictions remained in force, as did the ban on full in‑season track testing, although limited running was permitted on filming days and during Pirelli test sessions. The extra time at the factories allowed designers and engineers across the grid to refine and enhance the packages they had already mapped out for early‑season development, and many will emerge with significant aerodynamic and power‑unit upgrades for Miami and the subsequent Canadian Grand Prix.
McLaren, for example, had always earmarked Miami as a showcase for a major upgrade, recalling the game‑changing package they introduced at their Woking base in 2024. Andrea Stella, the team principal, explained that the revised calendar actually helped them and other teams streamline their upgrade programmes. "In our intent there was always the idea to deliver sort of a completely new car, especially from an aerodynamic upgrades point of view, for the North American races. The calendar change helped us, and I’m sure helped all the other teams, to focus on upgrading rather than racing," Stella said.
He added that fans can expect an "entirely new MCL40" across Miami and Canada, while also noting that the real test will be to see which competitors can extract the most performance from their upgrades within the same timeframe. The focus on Friday will be on how the various upgrade packages translate into lap times and whether the hierarchy of the grid shifts. Teams that struggled early, such as Aston Martin and Williams, will be hoping the break gave them a chance to make a noticeable leap forward. At the same time, the pause allowed all teams to digest the massive data sets generated by the three opening rounds of the highly complex 2026 cars, informing decisions on which aerodynamic concepts to prioritize for the rest of the year.
Drivers, too, have used the downtime to improve fitness, spend extra hours in simulators, and work closely with engineers to refine their understanding of the new machinery. Technical directors have been in ongoing talks with the FIA and F1 officials about regulatory tweaks that are slated to be introduced from Miami onward. The most prominent changes affect power‑unit energy deployment, aiming to make qualifying laps more naturally flat‑out and to reduce abrupt speed differentials during races. Because of these adjustments and the five‑week hiatus, the sole practice session on the Sprint weekend has been extended from 60 to 90 minutes, giving crews ample time to adapt to the new parameters.
Mercedes currently sit atop both the Drivers' and Constructors' Championships, having secured three wins in as many race weekends. Their lead over second‑placed Ferrari stands at 45 points, while McLaren, the two‑time reigning champions, trail by 89 points despite a strong second‑place finish at Suzuka. Red Bull, Haas and Alpine occupy the lower half of the table, with Red Bull only six points behind Alpine.
On the drivers' side, 19‑year‑old Kimi Antonelli unexpectedly leads the standings with 72 points, ahead of George Russell (63) and Charles Leclerc (49). Lewis Hamilton sits fourth, Lando Norris fifth, Oscar Piastri sixth, and Max Verstappen ninth after a modest start for Red Bull. The weekend schedule is packed: a press conference on Thursday evening, F2 practice and qualifying sessions on Friday, the Sprint race and build‑up activities on Saturday, and the Grand Prix itself on Sunday, followed by post‑race analysis.
All events will be broadcast live on Sky Sports F1, with streaming available via NOW. In summary, the Miami Grand Prix not only marks the resumption of the 2026 season but also serves as a pivotal reset point. Teams will debut a wave of upgrades, drivers will test new strategies, and the championship narrative could be reshaped dramatically as the sport moves deeper into its new regulatory era.
