Williams appears to be back on the right track, with the car build timed perfectly and running fine on the first day of testing. But what exactly is differerent on their new FW43 compared to the troubled 2019 car?
Williams tested a modified version of it´s barge boards during FP1.
It has a new connection to the chassis that seems to produce a bit of downwash to guide more air under the floor and to the diffusor. Also at the outer edge of the barge boards has some small modifications. The front vane has a slightly different conture at it´s front edge and the vertical strakes of the boomerang have a different angle at the lower end.
