One significant characteristic of the highly powerful RB19 has been its DRS advantage, which has proven crucial in propelling Max Verstappen and Sergio Perez to dominance on the racetrack. The advantage has been influential in delivering compelling qualifying results and granting both drivers a competitive edge during the races.
There were speculations earlier in the year regarding the magnitude of the DRS gain from Red Bull, leading to belief in a unique system employed to unleash its speed increment. However, rival teams have swiftly grasped the operative dynamics. Contrary to conjectures of it dwelling in a grey zone concerning racing rules, it is the balancing of drag levels towards the car’s rear that is primarily behind the system.
Red Bull has chosen to maintain a high drag ratio emanating from its rear wing than its beam wing, triggering a considerable increment in speed once the main wing opens. However, this approach is not a feasible option for rivals to emulate as their cars fail to generate the required performance from the diffuser. This need is crucial to reducing the beam wing, necessary for producing high downforce and augmenting rear-end stability.
Meanwhile, McLaren is applying more pressure in this aspect, having unveiled an efficient beam wing during the Belgian Grand Prix. The team hopes this change would alter the drag ratios at the rear, thereby unlocking further DRS benefits.
However, team principal Andrea Stella emphasized it would be a drawn-out process to build the car’s rear the same way Red Bull had managed in previous seasons. He remarked, “They seem to have pursued this concept for some time. Hence, it is reasonable in believing that they might be taking an advantage through their extensive experience in developing this kind of configuration. This has evidently been apparent over time.”
Tom McCullough, the performance director of Aston Martin, observed, “The updates we brought to Belgium were largely oriented towards these threads. The entire back end of the car is interconnected, encompassing the rear brake furniture, diffuser, beam and rear wing. The precision lies in calculating and applying the exact ratios between the components.”
