Mercedes' recent qualifying trick has shed light on the performance gap between George Russell and his teammate, Kimi Antonelli, during the Belgian Grand Prix practice. While the trick itself is fascinating, it has also exposed areas where Russell is losing out to Antonelli, particularly in terms of energy management and straight-line speed. This article delves into the data, offering insights into the performance gap and the potential reasons behind it. It also explores the broader implications of these findings and the challenges Russell faces in closing the championship points deficit.
One of the most striking revelations is the divergence in the timing of when Russell and Antonelli lift off the throttle during their quickest laps. This is particularly interesting because both drivers were lifting off at the end of their laps to avoid the need to follow typical ramp-down rates. The data shows that Russell comes off the gas around 70 meters before Antonelli, which costs him heavily as the gap between them expands by 0.4 seconds in the remaining time it takes them to cross the line. This offset is directly related to how much energy each driver has managed to harvest through the final chicane, with Antonelli doing a better job.
This snapshot given to us by the exit from the final corner may well explain what is going on around the rest of the lap where Russell is clearly losing time on the straights. If we look at Russell and Antonelli's fastest laps, Antonelli's top speed is a step ahead, and most of Russell's time is lost when at full throttle. This is particularly notable between the exit of La Source and Les Combe, where Russell goes from being three tenths up to 0.175s down. Another 0.175s is lost between Turns 6 and the entry to Turn 8, and then between the entry of Pouhon and the entry of the Fagnes Chicane, where a speed deficit of up to 8km/h loses him nearly 0.2 seconds.
The key to understanding this performance gap lies in how Russell approaches the corners and gets on top of the changing grip levels. The cars do not like sliding around a lot, with wheelspin and an aggressive driving approach. All that does is needlessly waste energy. Being smooth and consistent is the key, and that requires a mastery of perfectly judging grip levels to maximize energy harvesting. In FP1, Mercedes discovered a problem with one Russell's fuel flow meters, which had left him down on power compared to Antonelli. This matter was sorted for second practice, but the FP2 deficit appears more to be down to something else, possibly related to the characteristics of the current generation of cars that Russell does not like.
The answers to Russell's straight-line deficit and the top speed gap to his team-mate may well come in how he approaches the corners and getting on top of the changing grip levels. The perfect snapshot for us to see if he has mastered it on Saturday will be in spotting just where both Mercedes drivers lift off the throttle at the end of their laps. This will give us a clear indication of how well Russell is managing his energy and maximizing his speed on the straights.
In conclusion, Mercedes' qualifying trick has exposed areas where Russell is losing out to Antonelli, particularly in terms of energy management and straight-line speed. While the trick itself is fascinating, it has also raised important questions about Russell's driving style and energy management. As Russell continues to work on his performance, it will be interesting to see if he can close the championship points deficit and challenge for the crown.
