Pirelli explains why Formula 1’s real 2026 season only began after Miami
The opening races of the 2026 Formula 1 World Championship may have offered only a glimpse of what the sport’s new generation of cars was truly capable of. According to Pirelli, the championship has now entered a completely different phase, with teams finally unlocking the performance levels that engineers had expected before the season even started.
Months of development, continuous aerodynamic upgrades and a much deeper understanding of the new power units have dramatically changed the competitive landscape. What fans are witnessing today is a far more mature version of Formula 1 than the one seen during the opening Grands Prix.
This was one of the key topics discussed by Pirelli Motorsport Director Dario Marrafuschi during an interview with F1inGenerale.com, where he explained why performance has increased so noticeably since the Miami Grand Prix.
Rapid development transformed the competitive order
The beginning of every new Formula 1 regulation cycle follows a familiar pattern. While every team arrives at the opening race with its own interpretation of the rules, engineers immediately begin analysing rival concepts in search of ideas that can be adapted to their own cars.
That process has accelerated significantly during the 2026 season.
Marrafuschi indicated that the remarkable improvement seen across the grid has been driven by a combination of constant development, growing experience with the new regulations and the arrival of increasingly sophisticated aerodynamic upgrade packages. From the Miami Grand Prix onwards, virtually every Formula 1 team introduced important technical updates. Those developments, combined with a better understanding of the behaviour of the new cars, have produced a much higher rate of performance growth than many initially anticipated.
According to the Pirelli executive, the early months of a fresh technical era always generate an exceptionally fast development race. Teams carefully evaluate the solutions introduced by every competitor before selecting concepts that can be integrated into their own designs, creating an environment where progress becomes almost exponential.
This explains why lap times have continued falling so rapidly over recent races.
The cars are finally operating as Pirelli expected
One of the most significant revelations from Marrafuschi’s analysis concerns the tyres themselves.
When Pirelli developed its 2026 compounds, engineers worked using simulation targets based on the expected characteristics of the new Formula 1 cars. During the opening rounds, however, those targets had not yet been fully reached because the cars were still evolving.
As development progressed, that situation gradually changed. Marrafuschi explained that the teams have now entered the performance window Pirelli originally anticipated when designing its tyres, meaning the loads, operating conditions and overall behaviour of the cars now closely resemble the company’s original projections. In his assessment, Formula 1 is finally beginning to resemble the championship that Pirelli expected to see from the very first race of the season.
This also helps explain why tyre behaviour and degradation have become increasingly consistent over recent race weekends. Rather than being solely the result of drivers adapting to the new machinery, the improvements are largely linked to the cars themselves becoming significantly more refined.
Aerodynamics are only part of the story
While aerodynamic development has played a central role in the evolution of the 2026 Formula 1 cars, Marrafuschi stressed that another equally important factor continues to shape performance: energy management.
The latest generation of Formula 1 power units places much greater emphasis on electrical energy deployment than previous regulations, making software strategies and battery management crucial elements of overall competitiveness. Teams are still learning how to optimise these systems throughout an entire race weekend.
According to Marrafuschi, understanding how to deploy electrical energy efficiently remains one of the biggest challenges facing engineers, with much of the programming and strategic management resting in the hands of the teams themselves.
Every circuit presents different demands, requiring engineers to constantly adapt deployment maps, harvesting strategies and battery usage to maximise performance over a complete lap.
Lewis Hamilton and Kimi Antonelli provided the perfect example
To illustrate how decisive energy deployment has become under the new regulations, Marrafuschi highlighted Sprint Qualifying at Silverstone.
Although Lewis Hamilton and Kimi Antonelli ultimately recorded almost identical lap times, the way each driver achieved that result was remarkably different.
Marrafuschi explained that Antonelli gained a significant advantage during the opening sector, while Lewis Hamilton was considerably faster through the middle part of the lap before both drivers produced almost identical performances in the final sector. The explanation, he suggested, was not simply driver ability or aerodynamic efficiency, but rather the way each team chose to distribute electrical energy around the circuit.
The example perfectly demonstrates how modern Formula 1 has evolved beyond purely mechanical grip and aerodynamic performance.
Success increasingly depends on combining chassis balance, tyre management, aerodynamic efficiency and sophisticated energy deployment into a single optimised package.
The championship continues to evolve
The message emerging from Pirelli is clear: the 2026 Formula 1 season remains a work in progress. Every Grand Prix provides teams with additional data, allowing them to refine aerodynamic concepts, improve tyre understanding and unlock more performance from the new power units.
As development continues, the competitive order could still change further before the end of the championship. For Ferrari, where Lewis Hamilton and Charles Leclerc continue working to maximise the potential of the SF-26, and for every other constructor on the grid, the learning process is far from complete.
Marrafuschi’s analysis suggests that Formula 1 fans are only now witnessing the genuine capabilities of the new generation of cars. The opening races represented only the first stage of the learning curve, while the current phase marks the beginning of a more mature and significantly faster era under Formula 1’s latest technical regulations.
