Several teams have arrived at the Austrian Grand Prix weekend with new parts, including front-runners Red Bull and Ferrari.
At its home race, Red Bull has revised surfaces on the rear lower wishbone of its rear suspension to improve local flow stability.
Ferrari, meanwhile, has new parts as it looks to claw its way towards the front of the field following a difficult number of opening rounds.
The front wing has been redesigned, with elements including the mainplane, flap and endplate going through changes.
In addition, the Italian squad has arrived at the Red Bull Ring with a new floor, which works in tangent with the front wing redesign.
McLaren is another team that has brought upgrades to the round amid a slow start to the 2023 campaign.
The changes include a new sidepod inlet shape, new halo fairing, a fully revised floor, a reshaped sidepod and engine cover as well as updated cooling louvres.
Only Lando Norris will run the updated parts this weekend, with Oscar Piastri running the old-spec MCL60 package.
“The plan was both of us to have (it) in Silverstone but the team have done a very good job of getting one set forward for this weekend,” Piastri said.
“So yeah, looking forward to seeing how that performs and of course we’ve got a stable package on my side of things, we know exactly what it’s capable of, so still try to get into the points and do what we can.”
Elsewhere, Haas has brought a new nose, while AlphaTauri has introduced a new rear wing, beam wing and cooling lourves.
Williams, riding on the high from its strong result in Canada last time out, has new floor fences and a reprofiled front brake duct vane around the tyre edge.
Mercedes, Alpine, Alfa Romeo and Aston Martin have not listed upgrades for the event.
