The RB18 was fitted with a larger mirror casing for FP1 as the team helped the FIA to establish the criteria for any regulation changes that might come into force for 2023.
Aston Martin's new inverted rolled endplates which defy the intent of the regulations and create a more traditional upstand for the forward part of the endplate, allowing a wider span for the mainplane.
The view from under the Alfa Romeo C42's chassis without the bodywork in place reveals not only the bib that's being employed but also the sprung element that's in use, which in this case is a disc spring arrangement.
A look at the new floor arrangement at the front of the RB18, as introduced in France, whereby only a single, tall, fence sits on the outer boundary, with a three fence setup used on the leading edge of the floor.
Moving further down the floor, you might notice the blister beside the sidepod which has more of an angular appearance than it appears to have in other images.
A close-up of the RB18's diffuser, rear brake duct winglets and the beam wing, which returns to a double element arrangement having only been set up with the lower element over the course of the last few races to help reduce drag.
The cooling louvre panel on the upper shelf of the RB18's engine cover is opened up considerably in order to help reject the heat being generated within.
Alpine made changes to the floor edge in France, taking on more influence from the design seen over at Red Bull, with an 'ice skate' now also present on the underside of the floor too.
A nice view of the Ferrari F1-75's rear end, including the narrow central diffuser section and the step-like edge on the lower brake duct winglet fence.
Kiel probe rakes were attached to Sergio Perez's RB18 during FP1 as the team looked to gather some data related to the airflow's behaviour in order that it can correlate it with its simulation tools.
The single biggest change of the Haas update package is the redesign of the sidepods, with the team following in the footsteps of Ferrari which has opted for the bathtub style crevice and incorporated cooling gills.
Another angle showing off the new sidepod arrangement on the Haas VF-22 whilst also presenting us with a view of the floor's leading edge and the complimentary fences.
In order to help cope with the increased temperatures at a high downforce venue, Alpine has substantially increased the size of the cooling gills on the engine cover's shoulder.
A close-up of the Williams FW44's sidepod inlet, which bears a significant resemblance to the Ferrari solution since its upgrade, whilst the outer floor fence is unique in that it has a tall tab that's lent inward at the front of the surface.
Mercedes has reintroduced boomerang winglets on top of its halo in Hungary having not used them all season.
The Alfa Romeo C42 fitted with a raft of sensors to monitor flex on the floor's edge.
