The 2026 Formula One campaign gets underway this week after a forced hiatus in April, with the Miami Grand Prix being billed as the practical 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, taking to the Miami International Autodrome on Friday following a five‑week lull that resulted from the cancellation of the Bahrain and Saudi Arabian rounds originally slated in the 24‑race calendar.

Miami now hosts the fourth race weekend of the year and also the second Sprint event, but the month‑long interval that teams have enjoyed in their factories to develop the brand‑new 2026 cars adds a fresh dynamic to the return. Mercedes' rookie Kimi Antonelli seized the early lead in the drivers' standings with a win at Suzuka, meaning the gap between the first race and Miami is likely to produce a noticeably different spectacle. Ferrari team principal Frédéric Vasseur, whose outfit has been the closest challenger to the dominant Mercedes squad before the pause, described the upcoming weekend as essentially another season start. "Every team will arrive in Miami with fresh upgrades," Vasseur told Sky Sports Italy at Suzuka.

"They’ll have had time to refine the software, which is why I said a new championship will begin." Mercedes boss Toto Wolff echoed that sentiment, noting that his Silver Arrows have already secured three victories and a Sprint win, yet the break gives rivals a chance to close the gap. "Teams have learned, drivers are beginning to understand how to optimise these systems for their benefit, and we saw the first signs in Japan that looked like a home run in the first two races but that isn’t the whole story," Wolff said.

"Miami will be a restart for me as well. How will the upgrades work?

How have we fine‑tuned all the other systems? It’s going to be exciting." The original schedule had a Bahrain race on 12 April and a Saudi Arabian round on 19 April, but both were called off on safety grounds because of the Middle‑East conflict. With no feasible alternatives and no other events planned for April, the season suffered an unscheduled five‑week gap – the longest in‑season break since the opening two races of 1999, if summer and winter shutdowns are excluded.

Unlike those regulated shutdown periods, the eleven teams were free to continue development behind closed doors throughout April. The $215 million (£159 million) budget cap and the aerodynamic testing limits remained in force, as did the ban on full in‑season track testing (though limited runs were allowed during filming days and Pirelli test sessions). Development programmes for the early‑season cars had already been set before the Middle‑East events were cancelled, but the extra factory time undoubtedly gave designers and engineers across the grid the opportunity to refine and improve their packages ahead of Miami and the subsequent Canadian Grand Prix. McLaren, for example, had always targeted Miami – a venue where their Woking base introduced a revolutionary upgrade in 2024 – as a prime stage for an early‑season overhaul.

Andrea Stella, the team principal, explained last week: "Our intention was always to deliver essentially a new car, especially from an aerodynamic standpoint, for the North American races. The calendar change helped us and, I suspect, other teams to focus more on upgrades rather than racing. Across Miami and Canada we will showcase an entirely new MCL40.

This will be a test of who can add the most performance in the same timeframe, and we also have some ground to make up against Mercedes and, to a lesser extent, Ferrari." Consequently, much of the attention on Friday will centre on the upgrade packages each team brings, how those changes translate into lap times, and whether any significant reshuffle of the pecking order occurs. Teams that struggled early, such as Aston Martin and Williams, will hope the extended break yields a noticeable step up relative to the front‑runners. Equally important, the pause has allowed crews to digest the massive data trove generated by the opening three race weekends with the still‑complex 2026 machinery.

That information will shape not only aerodynamic priorities for the rest of the year but also strategies for operating the power units and managing tyre wear over a race weekend. Drivers, too, have used the time to focus on fitness, spend extra hours in simulators, and collaborate with engineers to fine‑tune their driving styles for the Miami circuit.

Meanwhile, technical directors have been in talks with the FIA about regulatory tweaks that are set to be introduced from Miami onward. The main changes target energy deployment, aiming to make qualifying laps feel more naturally flat‑out and to reduce abrupt speed differentials between cars during the race.

Because of these adjustments and the five‑week hiatus, the sole practice session on the Sprint weekend will be lengthened from 60 to 90 minutes, giving teams ample opportunity to adapt to the new parameters. Mercedes currently sit atop both the Drivers' and Constructors' Championships, having won three of the first three race weekends.

Their lead over second‑placed Ferrari stands at 45 points, while McLaren sit 89 points behind in third, buoyed by a strong second place at Suzuka. Red Bull find themselves further down the order, sitting behind Haas and Alpine in sixth with just 16 points.

In the drivers' standings, 19‑year‑old Kimi Antonelli surprisingly leads, followed by George Russell with 63 points, Charles Leclerc in third, Lewis Hamilton fourth, Lando Norris fifth, Oscar Piastri sixth, and Max Verstappen down in ninth as Red Bull struggle for pace. The weekend schedule includes a drivers' press conference on Thursday, F2 practice and qualifying sessions, the Miami Sprint qualifying and race on Friday and Saturday, and the Grand Prix itself on Sunday, with extensive coverage on Sky Sports F1 and streaming via NOW. Overall, the Miami Grand Prix marks not just a return to racing after an unprecedented break but also a pivotal moment where teams will showcase how effectively they have used the downtime to evolve their 2026 cars, set new performance benchmarks, and potentially reshape the championship narrative heading into the summer months.
