The 2026 Formula 1 calendar gets back on track this week with the Miami Grand Prix, an event that many commentators are describing as the effective launch of a "new championship" after the sport’s enforced hiatus. This marks the first occasion since the Japanese Grand Prix on March 29 that all teams will share the circuit on Friday, as the series emerges from a five‑week interruption caused by the cancellation of the Bahrain and Saudi Arabian rounds that were originally slated in the 24‑race programme.
Miami now serves as the fourth race weekend of the year and the second Sprint weekend, but the month‑long break has given every outfit a valuable window to develop their brand‑new 2026 cars back at their factories. Mercedes’ young driver Kimi Antonelli seized the championship lead with a win at Suzuka, meaning the return to competition is likely to feel different from the opening races.
Ferrari team principal Frédéric Vasseur, whose squad has been Mercedes’ closest challenger before the pause, said the weekend will feel like a fresh start to the campaign. "Everyone will bring new upgrades to Miami," Vasseur told Sky Sports Italy, adding that teams will have had time to refine their software, which is why he believes a "new championship" is about to begin. Mercedes boss Toto Wolff echoed the sentiment, noting that his Silver Arrows have claimed victory in all three races and the solitary Sprint so far, and that the break gives rivals 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 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 schedule had Bahrain on 12 April and Saudi Arabia on 19 April, but both events were called off for safety reasons linked to the Middle‑East conflict. With no feasible alternatives and no other races planned for April, the series endured an unscheduled five‑week gap – the longest in‑season hiatus since the opening two rounds of the 1999 season, discounting the usual summer and winter breaks.
Unlike those regulated shutdowns, the eleven teams were free to continue development behind closed doors throughout April. The $215 million (£159 million) budget cap and aerodynamic testing restrictions remain in force, as does the ban on full in‑season track testing, although limited running has been permitted during filming days and Pirelli test sessions. Development programmes for the early‑season cars had been set well before the Middle‑East rounds were scrapped, but the extra time in the factories has undoubtedly allowed engineers across the grid to fine‑tune their packages for Miami and the races that follow.
McLaren, for instance, has long viewed Miami as a showcase for a major upgrade, recalling how the Woking factory introduced a game‑changing aero package in 2024. Andrea Stella, McLaren’s team principal, confirmed that the team intends to unveil a substantially new version of the MCL‑40 for the North‑American races. "We could keep up with this plan, obviously 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," Stella explained.
He added that the combined Miami and Canadian events will reveal an "entirely new MCL‑40" and that the real test will be to see which competitors have extracted the most performance during the same development window. Consequently, Friday’s on‑track action will be closely watched for the impact of the various upgrade packages on lap times and whether any significant reshuffling of the pecking order occurs. Teams that struggled early, such as Aston Martin and Williams, will hope the break has allowed them to make bigger strides relative to the front‑runners.
Beyond hardware, the pause has given every team ample opportunity to digest the massive data set generated by the three opening race weekends with the complex 2026 machinery. This information informs not only aerodynamic priorities but also strategies for operating the power units and managing tyre wear over a race weekend.
Drivers, meanwhile, have used the unexpected free time for fitness work and extensive simulator sessions, sharpening their understanding of how to extract the maximum from their cars at Miami. Technical directors have also been in dialogue with the FIA and F1 management about regulatory tweaks slated to debut at Miami. The primary focus of the power‑unit changes is on energy deployment, aiming to make qualifying laps feel more natural and to reduce extreme closing speeds during races, thereby improving safety and on‑track competition. Because of these adjustments and the five‑week lull, the sole practice session on the Sprint weekend will be extended from 60 to 90 minutes, giving drivers and engineers extra time to adapt to the new parameters.
Mercedes currently leads both the Drivers’ and Constructors’ Championships, having secured three wins in the first three weekends. Their lead over second‑placed Ferrari stands at 45 points, while McLaren sits 89 points behind in third, buoyed by a strong second‑place finish at Suzuka. Red Bull, Haas and Alpine occupy the lower midfield positions with modest point totals.
In the drivers’ standings, 19‑year‑old Kimi Antonelli surprisingly tops the leaderboard with 72 points, followed by George Russell on 63 points. Charles Leclerc is third for Ferrari, 23 points adrift of Antonelli, with Lewis Hamilton fourth, Lando Norris fifth, Oscar Piastri sixth and Max Verstappen ninth, reflecting Red Bull’s early‑season struggles.
The weekend schedule is packed: Thursday features a drivers’ press conference, Friday hosts F2 practice and the Miami GP practice, Sprint qualifying and team‑boss press conference, Saturday includes the F2 sprint, the Sprint race itself, and qualifying, while Sunday culminates with the F2 feature race, the Grand Prix, and post‑race analysis. All sessions will be broadcast live on Sky Sports F1 and can be streamed via NOW without a contract. Overall, the Miami Grand Prix represents more than just a return to racing; it is a pivotal moment where teams will showcase the fruits of a month‑long development sprint, test new regulatory frameworks, and set the tone for the remainder of the 2026 season.
