The 2026 Formula 1 calendar gets back on track this week with the Miami Grand Prix, an event many are calling the effective launch of a "new championship" after the sport endured an enforced hiatus in April. For the first time since the Japanese Grand Prix on March 29, all of the teams will once again share the circuit on Friday at the Miami International Autodrome, ending a five‑week lull that resulted from the cancellation of the Bahrain and Saudi Arabian rounds originally slated in the 24‑race schedule. Miami now marks the fourth race weekend of the season and the second Sprint weekend, but the month‑long break has given every outfit a rare window to refine their brand‑new 2026 cars back at their factories.
Since Mercedes rookie Kimi Antonelli seized the championship lead with a win at Suzuka, the return to competition is expected to feel slightly different from the opening three events. Ferrari team principal Frederic Vasseur, whose squad had been Mercedes' closest challenger before the pause, described the upcoming weekend as another fresh start to the campaign.
"Everyone will bring new upgrades to Miami," Vasseur told Sky Sports Italy from Suzuka. "They'll have time to work on the software, which is why I said a new championship will start." Mercedes team boss Toto Wolff echoed the sentiment, noting that his Silver Arrows have claimed all three race victories and the solitary Sprint win so far, but that the break offers a chance for rivals to close the gap. "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 F1 race in Bahrain on April 12, followed by Saudi Arabia on April 19, but both events were called off on safety grounds because of the escalating conflict in the Middle East. With no viable alternatives and no other races pencilled in for April, the calendar was left with an unscheduled five‑week gap – the longest in‑season hiatus since the opening two rounds of the 1999 season, if summer and winter breaks are excluded. Unlike the regulated shutdowns that occur during the August summer pause or the off‑season winter lull, the teams were free to continue development behind closed doors throughout April.
The $215 million (£159 million) budget cap and the 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. Development programmes for the early‑season 2026 cars had already been set before the Middle Eastern rounds were cancelled, but the extra time in the factory allowed engineers across the grid to fine‑tune and enhance their packages for Miami and the races that follow. McLaren, for example, had always earmarked Miami as a venue to debut a major aerodynamic upgrade – a strategy that paid off in 2024 when the Woking factory introduced a game‑changing package. Andrea Stella, McLaren's team principal, said last week that the revised calendar actually helped the team: "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 fact that the calendar has been changed sort of helped a little bit, like I'm sure helped all the other teams that could work more streamlined towards upgrading the car rather than being busy with racing. Across Miami and Canada we will see an entirely new MCL40." Stella added that this approach would likely be mirrored by many of their rivals, turning the weekend into a true test of who can extract the most performance from the same development window.
The focus on Friday will therefore be on the upgrade packages each team brings, how those changes translate into lap times, and whether any significant reshuffle of the pecking order occurs. For outfits that have struggled early on – such as Aston Martin and Williams – the break provided a valuable opportunity to close the performance gap. Beyond hardware, the five‑week pause also gave teams ample time to digest the massive data sets generated during the opening three race weekends. Those insights are feeding into decisions about which aerodynamic elements to prioritise for the rest of the year and how to optimise power‑unit management, tyre usage and overall race strategy.
Drivers, too, have used the downtime for fitness work, additional simulator sessions and detailed debriefs with their engineers to hone their understanding of the new 2026 machinery. Technical directors have also been busy behind the scenes, negotiating with the FIA on a series of regulatory tweaks that are set to be introduced from Miami onward. The most notable changes target power‑unit energy deployment, aiming to make qualifying laps feel more naturally flat‑out and to reduce drastic speed differentials between cars during race phases where overtaking is otherwise difficult. Because of these adjustments, the sole practice session on the Sprint weekend – normally 60 minutes – has been extended to 90 minutes, giving drivers and engineers extra track time to adapt to the revised parameters.
Mercedes currently sit atop both the Drivers' and Constructors' Championships, having won three of the first three race weekends. Their dominance is reflected in a 45‑point lead over second‑placed Ferrari, while McLaren sit 89 points behind in third place after a strong second‑place finish at Suzuka. Red Bull, Haas and Alpine occupy the lower midfield positions, with Red Bull surprisingly down in sixth with just 16 points.
On the drivers' side, 19‑year‑old Kimi Antonelli – the unexpected champion after back‑to‑back wins in Japan – leads the standings with 72 points, followed by Mercedes veteran George Russell on 63 points. Ferrari's Charles Leclerc sits third, 23 points adrift of Antonelli, while Lewis Hamilton is fourth, eight points behind Leclerc. Lando Norris, Oscar Piastri, and Max Verstappen round out the top six, with Verstappen notably down in ninth after a difficult start to the season for Red Bull.
The weekend schedule is packed: Thursday features a drivers' press conference, Friday hosts the sole practice, F2 practice, qualifying and the Sprint qualifying, Saturday includes the Sprint race and the main qualifying session, and Sunday culminates with the Grand Prix itself followed by post‑race analysis. All sessions will be broadcast live on Sky Sports F1, with streaming available via NOW for those without a contract. In summary, Miami marks not just a return to racing after an unprecedented mid‑season break, but a genuine reset point for the 2026 Formula One championship.
Teams have used the unexpected downtime to develop upgrades, analyse data, and prepare for regulatory changes, while drivers have sharpened their fitness and simulation work. The result should be a highly competitive weekend where the true shape of the championship begins to emerge, setting the tone for the rest of the season.
