Oliver Bearman explains why Carlos Sainz’s Ferrari feedback left such a lasting impression

Haas driver Oliver Bearman has opened up about the impact Carlos Sainz made behind the scenes during his time at Ferrari, revealing just how influential the Spanish driver was in technical meetings and engineering debriefs. While Carlos Sainz now prepares for another Formula 1 season with Williams, Bearman has reflected on what he learned from observing him closely at Maranello.

Carlos Sainz’s move away from Ferrari came after the Italian team made the blockbuster decision to sign Lewis Hamilton, reshaping their long-term driver line-up alongside Charles Leclerc. That change forced Carlos Sainz to reassess his future in the driver market, eventually committing to Williams as part of their ambitious rebuild under team principal James Vowles.

As the 2026 Formula 1 season approaches, Carlos Sainz is aiming to help Williams close the gap to the midfield leaders despite what he has described as a challenging winter for the Grove-based outfit. Meanwhile, Oliver Bearman is looking to build on the momentum he generated at the end of the 2025 campaign, determined to establish himself as a consistent performer on the grid.

Oliver Bearman highlights Carlos Sainz’s technical strengths at Ferrari

Oliver Bearman and Carlos Sainz briefly shared the Ferrari environment when the British driver served as reserve driver for the Scuderia. The Ferrari junior was thrust into the spotlight when he replaced Carlos Sainz for his Formula 1 debut in Saudi Arabia, giving him rare access to Ferrari’s inner workings — including detailed engineering debriefs involving both Carlos Sainz and Charles Leclerc.

Speaking on the High Performance Podcast, Oliver Bearman explained that he holds Carlos Sainz in extremely high regard. He revealed that while acting as Ferrari reserve driver, he regularly listened in on technical discussions and was struck by the precision with which Carlos Sainz communicated his on-track sensations to engineers.

Oliver Bearman noted that many drivers can sense balance issues, tyre degradation patterns or aerodynamic instability, but far fewer can articulate those sensations in a way that directly translates into car development gains. According to the current Haas driver, Carlos Sainz had the rare ability to convert subjective feeling into actionable technical feedback, allowing Ferrari’s engineers to make meaningful performance improvements.

He also admitted that improving his own feedback skills has become a major focus, acknowledging that while he has made progress, he still has significant room to grow if he wants to reach the level demonstrated by Carlos Sainz at Ferrari.

Carlos Sainz’s influence extends to Williams’ long-term project

Carlos Sainz’s reputation as a detail-oriented driver has followed him to Williams. Under James Vowles, the historic British team climbed to fifth in the constructors’ championship last season, marking one of their strongest campaigns in recent memory. Alongside Alex Albon, Carlos Sainz helped elevate the team’s overall performance standards, even though Alex Albon narrowly finished ahead in the final standings.

James Vowles has publicly praised Carlos Sainz for his relentless pursuit of performance gains, describing him as a driver who demands excellence in every operational area. Vowles indicated that Carlos Sainz consistently pushes for incremental improvements across thousands of small details, from simulator preparation to race weekend execution, and that this mindset often leaves a lasting impact on the teams he represents.

There is a growing belief within the paddock that Carlos Sainz’s presence accelerates team development cycles. His structured approach to feedback mirrors the qualities that have defined champions like Lewis Hamilton and Charles Leclerc, both of whom have built reputations for technical input alongside outright speed.

Williams face early-season challenges despite Carlos Sainz’s arrival

Despite optimism surrounding Carlos Sainz’s arrival, Williams face an uphill battle at the start of the 2026 Formula 1 season. Testing data suggests their current car may be carrying excess weight compared to key midfield rivals, potentially compromising qualifying pace at circuits such as the Albert Park circuit, which will host the Australian Grand Prix in Melbourne.

Reaching the final phase of qualifying could prove difficult in the early rounds unless upgrades arrive quickly. However, Carlos Sainz’s analytical approach and proven development record may prove crucial in helping Williams unlock performance over the course of the season.

For Oliver Bearman, observing Carlos Sainz at Ferrari offered a masterclass in modern Formula 1 professionalism. With Lewis Hamilton and Charles Leclerc now forming Ferrari’s headline pairing, Carlos Sainz’s legacy at Maranello remains tied not only to race results but also to the technical foundations he helped strengthen.

As the new season unfolds, both Oliver Bearman and Carlos Sainz will be eager to demonstrate their growth — one as a rising star refining his craft, and the other as an established race winner seeking to guide Williams back toward the front of the Formula 1 grid.
