As part of an effort to improve the dominant RB19, Red Bull made modifications to the floor edge and the upper corner of its diffuser ahead of the Barcelona weekend.
The change at the rear of the car – where the tops corners of the diffuser were profiled for greater curvature – were particularly interesting because the team admitted it was an idea taken from other cars.
In its notes submitted to the FIA to explain the tweaks, Red Bull said: “A small increase in local load towards the trailing edge of the diffuser profile in the upper corners has been extracted with a more curved profile taking inspiration from competitor designs.”
While the team did not offer more details at the time, it has subsequently revealed that the design changes were something it had looked at for a while after originally spotting it on a Williams back in 2022.
