As previously reported by Motorsport.com, AlphaTauri prepared a significant upgrade to the AT04's floor for the 2023 season finale, which was intended as a research and development item for the 2024 car but is also expected to yield a "few tenths" in a last-ditch fight with Williams for P7 in the constructors' championship.
In the FIA's tech document released on Friday morning, AlphaTauri says it has reworked the main floor body as well as its edges and fences "to improve the local load generation of the forward floor".
