Andrea Kimi Antonelli has revealed that the pressure applied by Charles Leclerc during the Belgian Grand Prix forced Mercedes to change the energy deployment settings on his W17. The admission came during an illuminating cooldown-room discussion between the Spa-Francorchamps podium finishers, who also expressed their frustration with Formula 1’s complicated and unpredictable power management.
Charles Leclerc used the second Virtual Safety Car period to move ahead of the championship leader, turning the closing stages of the race into a direct battle for victory. Although Andrea Kimi Antonelli eventually reclaimed first place with a decisive overtake, the Ferrari driver remained close enough to force Mercedes to extract the maximum from its power unit.
Charles Leclerc and Kimi Antonelli fight for Belgian GP victory
The second half of the Belgian Grand Prix was dominated by the head-to-head contest between Charles Leclerc and Andrea Kimi Antonelli. The battle began after the second Virtual Safety Car was deployed because of debris on the circuit.
Ferrari took advantage of the neutralisation to bring Charles Leclerc into the pits. The timing of the stop allowed the Monegasque driver to emerge at the head of the field, leaving Andrea Kimi Antonelli with a lengthy pursuit before he could attempt the decisive pass on track.
The Mercedes driver eventually overtook Charles Leclerc and reclaimed the lead, but the contest did not end there. For several laps after losing first place, Charles Leclerc remained within range of the number 12 Mercedes and continued applying pressure from behind.
That sustained challenge forced Andrea Kimi Antonelli and the Mercedes engineers at Brackley to maximise the W17’s power unit performance. It also underlined how important electrical energy management had become at a circuit where the FIA’s revised limits created a significant MGU-K deployment challenge at Spa.
Kimi Antonelli reveals Mercedes deployment change
During the cooldown-room conversation, Andrea Kimi Antonelli confirmed a detail that had already emerged through Mercedes’ team radio during the Grand Prix. Charles Leclerc’s pressure had prompted the team to modify the W17’s energy deployment.
The objective was to prevent the Ferrari driver from remaining close enough to activate Overtake Mode and continue threatening Andrea Kimi Antonelli. Mercedes therefore changed how electrical energy was delivered around the lap, helping the championship leader create separation at strategically important points on the circuit.
The exchange offered further insight into a race in which Ferrari managed to challenge despite its expected straight-line limitations. Charles Leclerc later explained how the Scuderia had been able to fight for the Belgian GP victory despite its speed deficit.
Leclerc identifies where Antonelli gained the crucial advantage
The conversation between the top three finishers showed that Charles Leclerc had recognised exactly where Mercedes had altered its deployment. The Ferrari driver noticed that Andrea Kimi Antonelli was able to pull away before the final corner, limiting Leclerc’s opportunity to use Overtake Mode.
Andrea Kimi Antonelli confirmed that he was using maximum deployment through the final corner. Charles Leclerc then highlighted how aggressively the Mercedes driver was releasing the brakes at Turn 18 in an effort to create enough of a gap and prevent the Ferrari from remaining within attacking range.
The complete exchange between the three podium finishers was as follows:
Charles Leclerc: “The deployment was so different. It is so annoying.”
Max Verstappen: “At the start…”
Charles Leclerc: “Yes, at the start and then…”
Andrea Kimi Antonelli, speaking to Charles Leclerc: “When you were behind me, I had to change my deployment.”
Charles Leclerc: “Oh yes, I saw it, because before the final corner you were able to pull away a little…”
Andrea Kimi Antonelli: “Yes, I was at the maximum in the final corner.”
Charles Leclerc: “…and then at Turn 18 you were releasing the brakes like crazy to get me out of Overtake Mode.”
Drivers remain frustrated by unpredictable F1 energy management
Beyond the specific battle between Ferrari and Mercedes, the cooldown-room discussion highlighted the drivers’ wider frustration with Formula 1’s current approach to power delivery. Even after several races, the unusual and unpredictable nature of energy deployment remains difficult to understand and manage from inside the cockpit.
Deployment can vary considerably depending on battery charge, circuit position, the chosen engine mode and whether a driver is attacking or defending. At Spa, those factors were especially important because of the long full-throttle sections and the need to balance electrical energy use across the lap.
Ferrari and Mercedes had already spent the weekend studying those demands, with qualifying telemetry showing how Andrea Kimi Antonelli gained time through a combination of confidence and electrical energy deployment around Spa.
The discussion between Andrea Kimi Antonelli, Charles Leclerc and Max Verstappen therefore provided a rare glimpse into the tactical energy battle taking place behind the visible on-track action. Charles Leclerc’s pressure was strong enough to force Mercedes into a direct response, but the revised deployment ultimately helped Andrea Kimi Antonelli protect himself from Overtake Mode and complete his charge to victory.
