The Formula 1 teams brought a surprising amount of new parts to Austin this weekend for the United States Grand Prix.
For the all the new parts seen on the cars in the first free practice session on Friday, the underlying story is that teams are slowly converging on similar aero concepts, rather than lots of innovation being apparent.
This is not yet the end of the second year of the current regulations, and there are several areas of commonality between the cars. This weekend the front wing has been a focus and all the teams with R&D budget available have arrived with a similar concept.
