The Formula 1 race at Spa-Francorchamps revealed a surprising phenomenon: McLaren drivers, especially Oscar Piastri, have been affected by variations in the algorithms of their power unit engines. Piastri achieved a qualifying time two tenths slower than his teammate, Lando Norris, with a large part of this difference visible on the straight between Stavelot and the Bus Stop Chicane.
At this moment, the vehicles are in a power reduction phase, due to the depletion of electrical energy. This situation has led the team to conclude that Piastri’s performance is not due to his driving, but rather to engine management.
The team principal, Andrea Stella, explained that the drivers’ ability to maximize energy recovery at circuits like Spa is particularly critical. However, many of the factors contributing to the performance difference are beyond the control of the drivers. Stella emphasized that small variations in engine management can cause significant time losses during the race.
On the other hand, Piastri’s situation has paralleled another case: that of Mercedes driver George Russell, who alongside Kimi Antonelli, has seen a similar performance discrepancy. Data analysis between Mercedes engines has shown that it is not just about differences between teams, but also between teammates.
Engine manufacturers are working to address this issue, being aware that the variation in behavior of electric motors can complicate the prediction of their behaviors during the race. Power units constantly learn, adjusting to the different requirements of each lap, which causes each small alteration to have a large impact.
One of the challenges is “energy recovery”, which, if not managed properly, can force drivers to adjust their braking techniques, thus altering their driving style as they enter more and more corners.
The complexity of electric motors and energy management systems in current F1 means that both drivers and teams continue to fight against the unknown, striving to regain some advantage on the track as they approach the next race, a much tighter test at the Hungaroring circuit.
