The 2026 Formula 1 calendar gets back into motion this week after an enforced pause in April, with the Miami Grand Prix being billed as the effective launch of a "new championship". For the first time since the Japanese Grand Prix on March 29, all of the teams will be back on the circuit together on Friday at the Miami International Autodrome, ending a five‑week hiatus that arose from the cancellation of the Bahrain and Saudi Arabian rounds originally slated in the 24‑race schedule. Miami now hosts the fourth race weekend of the year and marks the second Sprint event of the season. However, the month‑long break gave every outfit a rare window to develop their brand‑new 2026 cars at their own facilities.
Since Mercedes youngster Kimi Antonelli seized the lead in the championship with a win at Suzuka, the return to racing is expected to feel different from the opening three meetings. Ferrari team principal Frédéric Vasseur, whose squad has been the nearest challenger to Mercedes before the pause, described the upcoming weekend as "another start to the season".
"Everyone will bring new upgrades to Miami," Vasseur told Sky Sports Italy, adding that teams will also have time to refine their software, which is why he believes a new championship is about to begin. Mercedes team boss Toto Wolff echoed the sentiment, noting that his Silver Arrows have claimed all three victories and the sole Sprint win so far, but that the break gives every rival a chance to close the gap.
"Teams have learned, drivers are starting to learn how to optimise these systems to their benefit and we saw the first signs in Japan that looked like a home run in the first two races but it 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 F1 race in Bahrain on 12 April, two weeks after Suzuka, followed by a Saudi Arabian round on 19 April.
Both events were scrapped on safety grounds because of the escalating conflict in the Middle East. With no feasible alternatives to slot into the calendar and no other races scheduled for April, the series was forced into an unscheduled five‑week lull – the longest in‑season gap since the opening two rounds of the 1999 campaign, if summer and winter breaks are excluded. Unlike the mandated summer shutdowns, where factories must close for a set period, 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‑season on‑track testing, although limited running was allowed on designated filming days and Pirelli test sessions.
Development programmes for early‑season cars had already been mapped out before the Middle Eastern rounds were cancelled, but the extra time in the factory gave designers and engineers a valuable opportunity to fine‑tune their packages for Miami and the races that follow. McLaren, for example, has long viewed Miami as a showcase for a major upgrade – the Woking base introduced a game‑changing aerodynamic package there in 2024. Andrea Stella, McLaren’s team principal, said the team intended to unveil a substantially revised MCL‑40 for the North American races. "The calendar change helped a little, giving all the teams more room to work on upgrades rather than being busy racing," Stella explained.
He added that both Miami and the subsequent Canadian Grand Prix should feature an "entirely new" McLaren, while acknowledging that rivals are likely to bring comparable improvements, turning the weekend into a test of who can extract the most performance within the same time frame. The focus on Friday will therefore be on the upgrade packages each team brings, how those changes translate into lap times, and whether the pecking order shifts dramatically. Teams that struggled early, such as Aston Martin and Williams, may see the break as a chance to make a substantial leap forward. Moreover, the pause allowed all crews to digest the massive data haul generated by the complex 2026 cars over the first three race weekends, informing decisions on aerodynamic priorities, power‑unit management, and race‑weekend strategies.
Drivers, too, have used the downtime for fitness work and extensive simulator sessions, collaborating with engineers to refine their driving styles for the new machinery. Meanwhile, technical directors have been in talks with the FIA about regulatory tweaks that are set to be introduced from Miami onward.
The most notable change concerns power‑unit regulations, targeting energy deployment to enable a more natural, flat‑out qualifying lap and to reduce drastic speed differentials during races. Because of these adjustments and the five‑week hiatus, the sole practice session at Miami – the only on‑track session of the Sprint weekend – has been extended from the usual 60 minutes to 90 minutes, giving teams and drivers extra time to adapt to the revised parameters. Mercedes currently sit atop both the Drivers' and Constructors' Championships, having secured three wins in the opening three weekends. Their lead over second‑placed Ferrari stands at 45 points, while McLaren, the two‑time defending champion, trails by 89 points in third place despite a strong second‑place finish at Suzuka.
Red Bull sit further back in sixth, with Haas and Alpine ahead of them. In the drivers' standings, 19‑year‑old Kimi Antonelli unexpectedly leads the pack, ahead of Mercedes veteran George Russell, who sits second. Charles Leclerc is third for Ferrari, followed by Lewis Hamilton in fourth, Lando Norris in fifth, Oscar Piastri in sixth, and Max Verstappen down in ninth, reflecting Red Bull’s early‑season struggles.
The weekend schedule includes a full slate of support events, from F2 practice and sprint races to a series of press conferences and analysis shows on Sky Sports. The Miami Grand Prix, as the season's second Sprint weekend, will be broadcast live on Sky Sports F1, with streaming available via NOW without a long‑term contract.
Overall, the return to racing in Miami is being framed as a fresh start for the 2026 championship. With a month of unrestricted development behind them, teams are poised to roll out significant upgrades, drivers are eager to test new strategies, and fans can expect a weekend that may reshape the competitive hierarchy as the new regulations take hold.
