In a revelation that has taken the Formula 1 world by storm, Lewis Hamilton’s telemetry data has uncovered a shocking technical flaw in Ferrari’s 2025 car — a flaw that appears to be a continuation of problems the team has struggled with for years. During the most recent Grand Prix weekend, engineers from Mercedes analyzed comparative data between Hamilton’s car and the Ferraris driven by Charles Leclerc and Carlos Sainz. The result? A clear and consistent pattern of rear-end instability during medium-speed corners — something that costs Ferrari critical tenths of a second per lap and severely affects tire wear and overall driver confidence.
This is not an isolated issue. In fact, it’s a haunting problem that dates back to the 2022 season. Despite updates to their aero package, suspension geometry, and even floor designs, Ferrari seems unable to completely solve this balance issue. Experts suggest the problem stems from a lack of consistent rear downforce generated by the diffuser, an overly aggressive rear suspension setup, and insufficient mid-corner feedback — all of which are visible in Hamilton’s telemetry comparison. The analysis shows that while the Ferrari can be competitive on straights and in high-speed corners, it noticeably struggles through medium-speed turns like those in Barcelona or Suzuka, where balance is key.
This discovery is especially significant given that Hamilton is set to join Ferrari in 2026. The fact that his team is already identifying Ferrari’s technical shortcomings indicates a serious intent to address them — but also sets a clear expectation that these issues must be fixed before his arrival. One Mercedes engineer reportedly stated, “Lewis doesn’t want to walk into a team that’s still fighting the same demons year after year.” Ferrari now faces immense pressure not just to be competitive this season, but to rebuild confidence ahead of one of the biggest transfers in modern F1 history.
The revelation has stirred reactions across the paddock. Charles Leclerc admitted, “We know where we need to improve,” while former Ferrari boss Mattia Binotto remarked that such problems are “systemic” and go beyond just technical components. Toto Wolff from Mercedes added that “the telemetry tells the real story — it always has.” Meanwhile, fans have expressed concern that if Ferrari cannot overcome these recurring flaws, they risk wasting the prime years of multiple world-class drivers.
Ultimately, this is more than a technical issue — it’s a test of Ferrari’s identity as a top-tier racing team. With Hamilton’s shocking telemetry shedding light on their Achilles’ heel, the Scuderia must respond with urgency and clarity. The question remains: will Ferrari finally overcome the ghost of instability that continues to haunt them, or will it follow them — and Hamilton — into 2026?
