A new rear wing is available to Ferrari this weekend with alterations made to the endplate noted by the arrows in this comparison. The upper rear corner cutout now features a serrated edge (red arrow), whilst the endplate is thinner in the rear section to accommodate larger upwash strikes (blue arrow) and the hanging vane portion of the endplate is now divided into three sections, rather than seven (yellow arrow).

During Friday’s Free Practice sessions McLaren continued to test the new nose solution that it took to Mugello (but didn’t race) and also tested a new front wing too. The wing features three main changes, two around the Y250 region, with the upper two flaps joined more intently to prevent the gap between them narrowing (blue arrow) and the lowermost flap tip has been blunted (red arrow). The outer section of the wing has seen the flaps relaxed to alter how the airflow moves across and around the front tyre.

Alfa Romeo has also optimised its rear wing endplate arrangement, adding a swordtail fish-like extension to the first hanging strake that then traverses the length of the others. It’s a very similar design detail to what we’ve seen Mercedes use for some time now.

Flo-viz paint on the Alpha Tauri AT01 as the team hope to gather visual confirmation of the flow structures around the car. Also note the stickers on the rear wing which are being monitored by hi-speed cameras in order that the footage can be reviewed later.

A closeup of the Haas VF20 front wing – nothing new here but still worth taking a look. Note the metal finish left exposed in the Y250 region, denoting the work undertaken to reduce the chance of flex in this very sensitive region.

Mercedes appear to have returned to the previous specification front wing for the Russian GP, the tell-tale sign being the split secondary flap.
