Lewis Hamilton has emerged as a central figure in Ferrari’s internal reset as the Scuderia prepares for the sweeping regulation changes coming into force for the 2026 Formula 1 season. After a deeply frustrating first year in Maranello, the seven-time world champion has pushed hard for structural and technical changes, determined to ensure that Ferrari does not repeat the mistakes that defined its disappointing 2025 campaign.
The 2025 season proved to be one of the most difficult of Lewis Hamilton’s career. Ferrari failed to secure a single victory, while Lewis Hamilton endured an unprecedented personal low by finishing an entire calendar year without a podium appearance. The SF-25 consistently lacked competitiveness against its main rivals, leaving both the Briton and his Maranello teammate and Charles Leclerc fighting an uphill battle on most race weekends.
Much of Ferrari’s struggle stemmed from a development direction that failed to address the core weaknesses identified by its drivers. The team invested heavily in an aggressive suspension concept and a sequence of mechanical upgrades that ultimately did not deliver the expected performance gains. Lewis Hamilton and Charles Leclerc had instead urged Ferrari to prioritise aerodynamic development, believing that overall car balance and stability were the limiting factors. That feedback was largely ignored at the time.
Ferrari later acknowledged internally that the 2025 development path had been flawed, conceding that the emphasis placed on suspension architecture came at the expense of broader aerodynamic progress. As part of a wider rethink ahead of the new technical cycle, Ferrari has confirmed that it will abandon the pull-rod suspension concept for 2026, signalling a clear break from the approach that failed to produce results.
Lewis Hamilton set the fastest time during Ferrari’s Barcelona shakedown with the SF-26, although such sessions offer little indication of the true competitive order at this stage. Even so, the early running suggested a driver far more at ease with the car, reinforcing the belief that Ferrari’s willingness to listen has already made a tangible difference.
Ferrari embrace Lewis Hamilton’s influence on SF-26 development
According to reports from the Italian daily newspaperLa Gazzetta dello Sport, Ferrari has significantly increased the level of influence afforded to its drivers during the development of the 2026 car. Both Lewis Hamilton and Charles Leclerc have repeatedly called for a more predictable and stable platform, particularly after the inconsistent behaviour of the SF-25 undermined confidence throughout 2025.
Ferrari’s engineering department has responded by actively incorporating driver feedback into key design decisions. Lewis Hamilton, in particular, is understood to have played a hands-on role in shaping several areas of the SF-26. His input extended beyond general balance characteristics and into detailed discussions surrounding power unit delivery, suspension behaviour, brake balance and even the ergonomics of the steering wheel controls.
This level of involvement marks a notable shift in Ferrari’s internal culture. Lewis Hamilton is believed to have provided extensive technical feedback based on his experience across multiple regulatory eras, placing particular emphasis on drivability under the upcoming 2026 regulations. After struggling to adapt to the outgoing generation of cars, he is optimistic that the new ruleset will better suit his driving style.
Initial impressions from the Barcelona running indicate that Lewis Hamilton has responded positively to the changes. Sources close to the team suggest he appears more motivated and energised, encouraged by the fact that Ferrari has acted on his recommendations rather than simply acknowledging them. Whether that renewed confidence translates into sustained performance once competitive running begins remains to be seen.
Lewis Hamilton drives wider changes behind the scenes
The scale of Lewis Hamilton’s dissatisfaction during 2025 was evident in his own assessment of the season, which he described internally as a nightmare. His frustration reached a peak midway through the year, underlining just how urgently he believed Ferrari needed to change course if it wanted to return to the front of the grid.
Those changes are now being implemented at multiple levels. One of the most significant developments is the restructuring of Lewis Hamilton’s engineering setup. Riccardo Adami will no longer serve as his race engineer in 2026, having been reassigned to a different role within Ferrari. In his place, Ferrari is expected to appoint Cédric Michel-Grosjean once the French engineer completes a period of gardening leave following his departure from McLaren.
Cédric Michel-Grosjean worked closely with Oscar Piastri during the 2025 season and arrives at Ferrari from a highly competitive environment, even though he has not previously held the role of primary race engineer. Ferrari views the appointment as a calculated gamble, with Lewis Hamilton believed to welcome the fresh perspective after a turbulent debut year with the team.
Changes are also taking place beyond Ferrari’s immediate structure. One of Lewis Hamilton’s long-time confidants, Marc Hynes, has moved to Cadillac, marking the second time the pair have gone their separate ways during Lewis Hamilton’s career. While the departure reduces the Briton’s inner circle, it also reflects a broader period of transition as he reshapes his working environment.
With Lewis Hamilton and Charles Leclerc now more closely aligned with Ferrari’s technical direction, the SF-26 represents more than just a new car. It is a test of whether Ferrari can evolve its decision-making culture and fully capitalise on the experience of one of the most successful drivers in Formula 1 history as the sport enters a new era in 2026.
