Jolyon Palmer has conducted a detailed analysis of Charles Leclerc’s sudden and significant loss of pace during the final stint of the Hungarian Grand Prix, suggesting that this unexpected drop-off may have been caused by one of three distinct and plausible scenarios. This investigation also raises the question of whether George Russell’s theory about Ferrari potentially pushing the boundaries of F1 technical regulations might be among the causes behind Leclerc’s performance issues.
During his regular and highly anticipated post-race debrief on Formula 1’s official channel, Jolyon Palmer carefully considered Leclerc’s own comments after the race, where the Monegasque driver indicated he had experienced what he described as a chassis-related issue. Palmer expanded on this by pointing out that it seemed unlikely that the problem was connected to the power unit itself. Instead, he focused on three main possibilities that could explain the sudden drop in pace: either some form of physical damage picked up by Charles Leclerc’s car during the race, an incorrect or faulty front wing adjustment made by the Ferrari mechanics during the critical pit stop, or the possibility that Ferrari was operating their car on the very edge of the current Formula 1 technical regulations, thus risking penalties.
Palmer further highlighted that the Mercedes team, whose driver George Russell was closely involved in the scenario, had quickly suspected the latter issue. They specifically pointed to the risk of excessive wear on the plank—a wooden or composite skid block underneath the car that regulates ride height and floor wear—as a likely cause of concern. Palmer considered this to be the most plausible explanation, stating that the data available appeared to support this hypothesis more strongly than the others.
By comparing the lap times of Charles Leclerc with those of George Russell, Palmer demonstrated that while Leclerc was quicker during the first two stints of the Hungarian Grand Prix, his performance dramatically declined during the final stint. He explained that by lap 48, which marked the beginning of the last stint, George Russell had started closing the gap significantly, catching up to Leclerc at a rapid pace. This was particularly notable because Ferrari was no longer utilizing full energy deployment on the straights, indicating that their power unit was being restricted or managed conservatively. Additionally, Palmer pointed out that Leclerc had also lost pace through the corners, further emphasizing the considerable loss of overall speed and grip.
Palmer then delved into the technical possibilities behind Ferrari’s strategy, questioning whether the Italian team might have deliberately altered tyre pressures during the Hungarian Grand Prix in order to avoid potential disqualification due to regulatory non-compliance. He speculated that Ferrari could have chosen to increase tyre pressures, a move which would effectively raise the ride height of the car, thus reducing the risk of excessive plank wear. While this adjustment would inevitably lead to a sacrifice in grip and cornering speed, it would allow the car to remain within the strict legal limits defined by the FIA.
He further elaborated that during a standard pit stop, the only adjustments that teams can make to a Formula 1 car are to the front wing angle—something Ferrari did change during Leclerc’s stop—or to the tyre pressures. Usually, teams operate their tyres at or just above the minimum pressures mandated by Pirelli, the official tyre supplier. However, deliberately increasing tyre pressures beyond the usual threshold would result in lifting the car’s floor higher off the track surface. This action, while detrimental to outright speed and handling, would ensure the car stayed legal under current technical regulations.
Palmer concluded his analysis by suggesting that Ferrari’s engineers and technical staff likely already have a clear understanding of the exact reason behind Charles Leclerc’s sudden and unexpected loss of pace. While the logic behind Ferrari’s possible tyre pressure strategy is understandable from a regulatory compliance perspective, the resulting reduction in performance was severe enough that Leclerc was left virtually defenseless on track. This drastic loss of pace ultimately cost Charles Leclerc the chance to maintain his position and secure a podium finish at the Hungarian Grand Prix, a disappointment for the Ferrari driver and the Scuderia alike.
