At first it looked like only the sidepod inlet was changed, but then it became clear sidepod bodywork is new as well. We also have new rear wing flap tip (as suggested by Formu1a Uno team), engine cover and cooling outlet redesign.
As far as I can tell, the floor is old/launch spec, absolutely no surface looks different. Most likely will be fitted later today, like they did with pre-Austria comparative tests during Filming Day 2 last year.
Novelties:
- fairly conventional and extended inlet, slightly elongated top lip, seemingly of the same size as before
- new mirror vane design
- new Halo winglet design, no more S duct outlet in the rear
- bigger and more squared sidepod shape (possibly now chasing some actual local suction load, ie downforce)
- engine cover and cooling outlet look like a fairly big change, will be interesting to see how this area will be adapted from track to track
- rear wing flap tip redesign, in line with sharp flat edge that RB introduced
Not bad, but definitely not an EVO/B car, just a natural update evolution
