Few engineers understand both Ferrari and Mercedes from the inside as deeply as Aldo Costa. The former Ferrari technical director, who played a major role during one of the Scuderia’s most successful eras before later becoming a key architect of Mercedes’ dominant hybrid-era empire, has offered revealing insight into why the working cultures at the two Formula 1 giants have historically produced very different outcomes.
At a time when Ferrari continues its search for a championship-winning formula with Lewis Hamilton and Charles Leclerc leading the driver line-up, Costa’s reflections offer a fascinating look into the structural and cultural differences that may still influence performance at the highest level.
Why Ferrari’s internal culture created limitations
Aldo Costa spent decades inside Maranello, arriving in the early 1990s and growing through the organisation during Ferrari’s legendary Michael Schumacher era, initially working alongside Rory Byrne before eventually rising to technical director. He was also involved in the development of Ferrari’s last championship-winning car.
Despite describing Ferrari as an extraordinary place to work, Costa suggested that the internal environment could become increasingly restrictive as responsibilities grew.
Reflecting on his experience, the Italian engineer explained that the pressure associated with working at Ferrari became so intense over time that it began to affect his personal wellbeing, ultimately contributing to his decision to leave the role.
He also pointed to a deeper structural issue: despite years of experience and seniority, he felt he was still perceived internally as someone who had simply grown up within the Ferrari system rather than as a figure fully empowered to drive transformative change.
That limitation, according to Costa’s recollections, became evident in infrastructure discussions as well. One notable example involved plans for a larger, more advanced wind tunnel project that never received final approval from Ferrari leadership.
For a Formula 1 team operating in an era increasingly defined by simulation tools, aerodynamic precision and aggressive development cycles, those kinds of strategic decisions can have long-term consequences.
Mercedes offered a completely different engineering environment
When Aldo Costa joined Mercedes in 2011, the circumstances could hardly have been more different.
The Brackley-based operation was still rebuilding after the transition from Brawn GP, operating under financial constraints and with a reduced workforce. There was no guarantee the project would evolve into the dominant force it eventually became. Initially, Costa arrived as an outsider — a senior Ferrari figure entering a British team with its own culture, expectations and uncertainty.
But rather than resistance becoming a long-term obstacle, the environment evolved into something Costa described as far more collaborative and open. He explained that one of the key differences at Mercedes was the willingness to encourage open technical debate, challenge ideas freely and create an atmosphere where engineers could exchange views without rigid hierarchy getting in the way of progress. That cultural transformation became one of the foundations of Mercedes’ extraordinary rise.
From 2014 onward, with the introduction of the turbo-hybrid power unit regulations, Mercedes established one of the most dominant dynasties in Formula 1 history, rewriting the competitive order for nearly a decade.
What this means for Ferrari today
Costa’s observations inevitably raise bigger questions about Ferrari’s current structure.
The Scuderia has made significant efforts under Frederic Vasseur to modernise its working methods, streamline decision-making and create a less politically constrained technical environment. The arrival of Lewis Hamilton has added further pressure to deliver immediate progress, while Charles Leclerc remains the long-term competitive cornerstone of the project.
But Formula 1 success today depends on far more than driver talent or raw budget. It requires an engineering culture capable of rapid iteration, honest internal communication, decisive leadership and the freedom to pursue innovation aggressively.
If Ferrari is to consistently challenge Mercedes, Red Bull and McLaren at the very front of Formula 1 once again, Costa’s reflections suggest that technical philosophy alone may not be enough — cultural evolution may be just as critical.
