Okay (finally) the first update for the Australasian test and pretty much the melbourne package.
Different front wing, the additional winglet in the inner tip is gone, now sporting a large area of nothing. This works much better downstream generating a much smaller vortex higher up. The AoA was allowed to be higher too in this area due to this, creating a small 'diffuser' here, increasing downforce.
The smaller cascade also is new, now featuring 2 wings, although with lower AoA, also turning air a little bit to the outside.
Further down the wing the outer piece of the end plate is gone as well as on the outer edge the wing being split up in two.
The footplate now features a bend downwards which continues in a strake, similar to the Wiliams front wing, reduces sensitivity in this area.
The car now got barge boards under the nose, bending towards the center this pushes air away to the sides, increasing efficiency as well as downforce.
The car features a new barge board package, with a different floor lip, all increasing floor efficiency. This area isnt fully done yet and I am not very happy with it currently, lots of changes coming here.
The sidepod intake has changed too, now featuring a gurney tab at its entry, this sheds off the boundary layer, in turn reducing duct drag and improving cooling.
Also there is a small winglet in the area that is used a lot in recent years, this piece helps the air to stay attached over the sidepod in this critical area.
There also is new rear bodywork, with a small pair of grills to improve cooling.
The fin was changed too, now having an fully vertical end. This gives a more constant flow under yaw, this reduces sensitivity under yaw.
The front of the diffuser was changed, instead of a smooth flow over the diffuser now there is a hard edge, with the same shape as the diffuser itself. This, together with the fins in this area create a high pressure zone and also high pressure over the rest of the diffuser, increasing downforce.
The central gurney now is full height increasing downforce, together with that there is the addition of multiple strakes.
Also the car itself ran much higher AoA on its wings, increasing downforce, which I believe the car is lacking.
On the performance side the car is unreliable and currently in the Adalaide test seems a good 2 seconds off the pace, it is going to be a tough season.
