The 2026 Formula 1 calendar gets back under way this week after a forced pause in April, with the Miami Grand Prix being billed as the effective kick‑off of a "new championship". For the first time since the Japanese Grand Prix on 29 March, all teams will be together on the track again, this time at the Miami International Autodrome, after a five‑week hiatus that was originally intended for the Bahrain and Saudi Arabian rounds in the 24‑race schedule. Miami now marks 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 machines. Since Mercedes rookie Kimi Antonelli seized the early lead with a win at Suzuka, teams have been able to return to their factories and fine‑tune both hardware and software.
As a result, the return to racing is expected to feel different from a typical early‑season sprint. Ferrari team principal Frédéric Vasseur, whose squad has been the closest challenger to Mercedes in the pre‑break races, described the upcoming weekend as "another start to the season". "Everyone will bring new upgrades to Miami," he 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 boss Toto Wolff echoed the sentiment, noting that the Silver Arrows have won all three races and the sole Sprint so far, but that the break gives every rival a chance to catch up. "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 plan had seen a race in Bahrain on 12 April, followed by Saudi Arabia a week later, but both events were cancelled on safety grounds because of the escalating conflict in the Middle East.
With no viable alternatives and no other races scheduled for April, the season suffered an unscheduled five‑week gap – the longest in‑season pause since the opening two rounds of 1999, if summer and winter breaks are excluded. Unlike those regulated shutdowns, the eleven teams were free to keep working behind closed doors throughout April, albeit under the constraints of the $215 million (≈£159 million) budget cap, aerodynamic testing limits, and the ban on full in‑season track testing (only limited filming and Pirelli test days were permitted).
That extra time in the factories has undoubtedly allowed designers and engineers across the grid to refine the packages they had originally prepared for the early part of the year. McLaren, for example, had always targeted Miami as a showcase for a major aerodynamic upgrade – a strategy that paid off in 2024 when the Woking base introduced a game‑changing element.
Andrea Stella, McLaren’s team principal, explained that the calendar reshuffle actually helped all teams concentrate on development rather than race logistics. "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," Stella said. "We could keep up with this plan; 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.
This will be a test of who has been able to add more performance within the same time frame." Consequently, the focus from Friday will be on the upgrade packages each team brings, how those translate into lap times, and whether the hierarchy of the grid shifts dramatically. Teams that struggled early, such as Aston Martin and Williams, may view the break as a lifeline and hope to make significant gains relative to the frontrunners. Beyond hardware, the hiatus gave engineers ample opportunity to digest the massive data set generated by the first three race weekends.
The 2026 cars are among the most complex in the sport’s history, and understanding the nuances of the new aerodynamic regulations, power‑unit limits, and energy‑deployment rules is critical. That knowledge will shape not only the design of future upgrades but also race‑weekend strategies, including how to extract maximum performance from the power unit while managing tyre wear and fuel consumption.
Drivers have also benefited from the unexpected downtime. In addition to maintaining their physical fitness, many have spent countless hours in simulators, working with engineers to fine‑tune braking points, corner‑entry speeds, and the deployment of the revised energy‑recovery systems. The new power‑unit tweaks, agreed with the FIA ahead of Miami, aim to make qualifying laps more naturally flat‑out and to reduce abrupt speed differentials during races, which should lead to cleaner overtaking opportunities.
To accommodate these changes, the sole practice session on the Sprint weekend has been extended from 60 to 90 minutes, giving teams a longer window to test the updated parameters and to validate their upgrades under real‑world conditions. At the start of the season, Mercedes held a commanding lead in both the Drivers’ and Constructors’ Championships, having secured three wins from the first three weekends. Their advantage 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, with Red Bull trailing by just 16 points. On the drivers’ side, 19‑year‑old Kimi Antonelli surprisingly tops the standings with 72 points, ahead of Mercedes veteran George Russell (63 points) after Antonelli’s back‑to‑back victories. Ferrari’s Charles Leclerc occupies third place, 23 points adrift of Antonelli, while Lewis Hamilton (Ferrari’s second driver) is eight points further back in fourth. Lando Norris, the reigning champion, sits fifth with 25 points, followed by Oscar Piastri in sixth (21 points) and Max Verstappen in ninth (12 points), reflecting Red Bull’s early‑season struggles.
The weekend schedule is packed: a drivers’ press conference on Thursday evening, F2 practice and qualifying sessions, the Miami Sprint on Saturday, and the Grand Prix itself on Sunday, with multiple Sky Sports analysis programmes surrounding each session. Fans can stream every race via NOW, with no long‑term contract required.
In summary, the Miami Grand Prix marks more than just the resumption of racing after a forced break; it represents a genuine reset for the 2026 Formula 1 championship. Teams have used the unexpected pause to develop upgrades, analyse data, and adapt to new regulatory tweaks, while drivers have sharpened their skills both physically and virtually. As the field reconvenes, the true impact of these efforts will be measured on the streets of Miami, potentially reshaping the competitive order for the remainder of the season.
