During the Spanish Grand Prix, Red Bull Racing surprised onlookers with modifications to their floor’s edge wing and diffuser, adopting design elements commonly seen on their competitors’ cars. It appears that Adrian Newey, renowned technical guru, spotted these features during his customary grid walks. Red Bull’s engineering team then put their own unique twist on these solutions, which have been tried and tested by other teams over an extended period.
Implementing these changes is not as straightforward as copying and pasting solutions from elsewhere. They must harmonize with Red Bull’s existing architecture, requiring the team to create its own development branch within the overall design framework. This branch will likely undergo further optimization as the season progresses, ensuring maximum performance gains.
The forward section of Red Bull’s edge wing already mimics the cut-out in the floor beneath, featuring a C-shaped profile. However, beyond this point, an additional strake has been added to the upturned scroll section of the wing. This innovation aims to guide the airflow that is redirected from the floor in this specific area.
Furthermore, the upper corner of the diffuser has been modified with an inverted pocket arrangement, similar to designs employed by many competitors. This alteration not only affects the diffuser’s internal performance but also influences the behavior of the airflow over the upper corner.
In contrast, Mercedes took a somewhat retrograde step at the Spanish Grand Prix by removing the upper slat element from its wing mirror assembly. The inboard stalk is now directly mounted to the side of the mirror housing. This adjustment ensures that the airflow around the mirror housing’s bluff body aligns better with the modifications made to the sidepods.
Mercedes also explored various solutions during Friday’s free practice sessions, experimenting with both medium and high downforce rear wings. Ultimately, they settled on the high downforce wing for qualifying and the race. Additionally, the team tested a larger rear cooling outlet option before reverting to the narrower solution for the competitive sessions, indicating their meticulous search for the ideal setup for the W14.
While Aston Martin has had a strong start to the season, the surrounding teams have been making significant changes in an attempt to close the performance gap. In response, Aston Martin introduced a host of new parts in Spain to maintain their competitive edge.
Their front wing underwent a complete overhaul as part of the update package. The distribution of the upper two flaps was altered to create a more uniform design, eliminating the previously swooped section ahead of the front tire. This change aligns Aston Martin’s front wing with the designs seen across the grid. It also opens up development opportunities for the outboard section, where the flap and endplate juncture underwent redesigning. The second, third, and fourth elements are now stepped away from the endplate and twisted to promote increased outwash.
The adjustments to the front wing prompted Aston Martin to reset the angle of the camera pods mounted on the side of the nose, considering the altered airflow reaching them.
At the rear of the car, further enhancements were made to the latest rear wing specification, with the main changes already tested during the Monaco Grand Prix. These modifications include a different attachment method for the tip section of the endplate, which now sits inboard and turned inward instead of merging with the outer edge. These alterations affect the pressure gradient and alter the vorticity of the tip vortex. Furthermore, the inboard geometry of the endplate has been adjusted, featuring a swage line with a steeper angle similar to that used on the outer face. This adjustment not only impacts aerodynamics directly but also influences the surrounding surfaces, prompting modifications to the beam wing to capitalize on these changes.
Aston Martin also briefly tested a pair of additional guide vanes atop the halo, aiming to refine the flow around the safety structure and enhance downstream performance in upcoming races. Although not mentioned in the car presentation submission, it is likely that Aston Martin will introduce a more polished variant of these guide vanes in the future.
