F1 Testing 2025: Digging into the details on day 2

McLaren MCL39 rear wing

An overview of McLaren’s rear wing assembly, with attention to be paid to the shape of the endplate and how it merges with the mainplane. Also note the deep, upwashing, swage line on the exterior of the endplate, below the Dropbox sponsorship logo.

Williams FW47 halo fairing

A close up of the fairing around the rear leg of the halo on the Williams FW47, which as you can see is a separate panel to enable the team to make modifications without needing to change the entire fairing. In Williams case they have a very thin tail-like upstand, with a winglet mounted on the side.
