4 — Williams' new rear wing
Williams also brought a major update to Austria, with its FW37 sporting a heavily revised rear wing at the Red Bull Ring. Its end-plates have a more rectangular shape (compare white arrows) and feature a larger horizontal slot (see white arrows) as well as an extra horizontal edge (see blue arrows). What’s more, the upper flap, which opens when DRS is activated, now has a V-shaped dent in the middle.
