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.
Russel have another base start, he Lost ground due to starting slot? He pass last on First corner with Latifi.
Te car development from te start of the season basically go well, and now the car have more stable performance in race than It have in mid season. Maybe now the fw43 have similar performance of Alfa and Haas but not capitalise in scoring points.
Finally I think I understand why the Last Williams cars have that big bulge around the engine.
1-it's because their tub is particularly wide in that area and 2-because the bodywork needs to circumvent the intercooler-to-manifold pipe (left hand sidepod) which needs to bypass the wide tub flanks too.
So why is their tub so massive in that area? Maybe because the monocoque, and fuel tank, sides are deeply undercut at their base (to free some space for the coolers) so, to keep it low and short, they need to widen the top of the tub in order to fit a big enough fuel tank..?
