Ferrari is preparing one final major development push of the 2026 Formula 1 season at the United States Grand Prix in Austin, with an upgrade package designed not only to improve the SF-26 but also to provide a valuable foundation for 2027. While Red Bull, Mercedes and McLaren have already introduced the bulk of their major developments, the Maranello team is looking to exploit its improved simulator-to-track correlation to optimise the car’s performance and efficiency.
The upcoming Ferrari Austin upgrades therefore represent more than a late-season attempt to close the gap to its rivals. The team believes that the progress made in understanding the relationship between virtual development and real-world performance could help maximise the effectiveness of its latest components, while also supporting its preparations for next year’s championship.
Red Bull, Mercedes and McLaren take different development paths
Does Red Bull intend to win all the remaining races of the 2026 Formula 1 championship? Probably. The RB22 has demonstrated genuine competitiveness for three consecutive Grands Prix, beginning with a significant performance step in Azerbaijan, continuing in Malaysia and culminating in an utterly dominant Singapore Grand Prix, where Max Verstappen established a commanding advantage over the field.
These three circuits feature very different layouts, giving the Milton Keynes team good reason to believe that it now has the potential to fight at the front consistently for the remainder of the season. That assessment appears justified, although the competitive order can change extremely quickly in modern Formula 1. Red Bull has undoubtedly done an excellent job, but Mercedes has also contributed to the shift in the balance of power.
Consider the situation in Baku, where George Russell won in the Mercedes W17 before any of the eleven updates subsequently introduced at Sepang had been fitted to the car. The extensive Malaysian upgrade package appears to have moved the Mercedes away from its optimum operating window, forcing the team to search for a solution through several comparative tests during the following Singapore weekend.
Those experiments also included the debut of a new front wing. Ultimately, Mercedes decided against continuing with the new specification, having again struggled considerably, much as it had in Malaysia. The situation only began to improve during the second half of the Singapore Grand Prix weekend.
Kimi Antonelli eventually found a better feeling with the car, allowing his race pace to improve. Andrew Shovlin was clear in his assessment: the new package still requires refinement, but it offers greater performance potential once its characteristics are properly understood.
McLaren faces a different but equally complicated situation. After producing two exceptional performances across the Hungarian and Dutch Grands Prix, the British team subsequently lost its way. Once again, upgrades appear to be the main cause, with substantial modifications introduced in Azerbaijan altering the car’s balance.
Across three race weekends, McLaren has been unable to make those developments work as originally intended. The difficulties experienced by both Mercedes and McLaren demonstrate how an upgrade can change a car’s operating characteristics without immediately delivering the expected results.
Ferrari Austin upgrades represent one final push towards F1 2027
Ferrari, meanwhile, has followed a markedly different development strategy. The Maranello team has not introduced any significant upgrades since the Spanish Grand Prix, having initially chosen to accelerate development during the first third of the 2026 championship. The expectation was that bringing improvements forward would provide a clear competitive advantage, although the approach has delivered only limited benefits for several reasons.
Nevertheless, Ferrari has no intention of giving up on the current campaign, particularly because every new development is also being assessed with the 2027 Formula 1 season in mind. This explains the importance of the final upgrade package, which is expected to debut at the United States Grand Prix at the Circuit of The Americas.
The Austin weekend should provide an important opportunity to establish whether Ferrari is simply evolving concepts already present on the SF-26 or preparing more substantial technical changes that reflect a different development philosophy. That distinction matters because the lessons learned from the final stages of 2026 could influence the direction of the team’s next car.
The upcoming package also follows Charles Leclerc’s concerns about Ferrari losing ground to its Formula 1 rivals, making Austin an important test of the team’s ability to respond through development.
Red Bull, Mercedes and McLaren have largely completed their major upgrade programmes for the season. Their remaining changes are expected to consist mainly of smaller refinements designed to adapt their cars to the characteristics of individual circuits.
In that context, the impact of Ferrari’s final developments could prove particularly significant. However, the SF-26’s deficit in power-unit performance is expected to remain evident, limiting how much of the gap can be eliminated through improvements elsewhere on the car. The wider competitive picture can also be examined through Ferrari’s recent performance analysis and the progress made by its rivals.
Lewis Hamilton and Charles Leclerc encouraged by Ferrari simulator correlation
One of the most encouraging developments for Ferrari concerns the relationship between its simulator predictions and the behaviour of the car on track. Lewis Hamilton had previously highlighted several problems in this area, but those difficulties now appear to have been resolved.
The seven-time world champion has already returned to working extensively with the car in Ferrari’s virtual development environment, while Charles Leclerc recently offered further encouragement. During the Singapore Grand Prix weekend, the Monegasque explained that the behaviour predicted at the factory was now consistently being reproduced on track.
This represents an important improvement for Ferrari, especially when assessing how new components will influence the car’s performance. More reliable correlation can help engineers understand whether changes tested in the simulator are likely to deliver the intended behaviour once fitted to the SF-26.
It also offers a more promising foundation for the final development package, particularly after a season in which extracting the expected performance from technical changes has proved difficult for several leading teams. Ferrari’s recent Singapore Grand Prix technical analysis provides further context on the car’s remaining weaknesses and the areas where improvement is still required.
Ferrari hopes Austin developments will support its 2027 F1 project
There is consequently considerable optimism that Ferrari’s final updates can work as intended. Their importance extends beyond the immediate results of the 2026 championship, because this last phase of development is also intended to support the technical work being carried out for next season.
One question nevertheless remains unanswered: was the arrival of the upgrade package delayed by Ferrari’s efforts to restore reliable simulator-to-track correlation, or has the programme simply followed the timetable originally established by the Maranello engineers?
That distinction has yet to become clear. What matters now is whether the latest components deliver the expected improvement when tested at Austin and whether Ferrari can use the resulting information to strengthen its preparation for 2027.
