McLaren has introduced a “complete floor” revision for this weekend’s Formula 1 British Grand Prix, leading a raft of upgrades across the grid.
The Woking-based squad has brought two revisions to its MCL39, the first to result “in improved flow conditioning and a redistribution of suction to gain overall aerodynamic performance.”
Its rear corner has also been changed, in a bid to improve “aerodynamic and brake cooling performance.”
Red Bull has placed its focus on the floor of its RB21, with reprofiled surfaces which correlate with its second change, a lateral repositioning of the leading edges of the floor.
The technical notes say the change is to encourage more load without breaking stability of the flow.
Aston Martin’s AMR25 has four updates, three of which relate to its floor. Red Bull-style changes to the body, fences and edge come in to improve the flow conditioning, as well as a tweaked engine cover that works in conjunction with them.
A recurring theme is present just down the garage at Haas, producing similar floor changes, as well as a tweaked sidepod inlet.
Racing Bulls has brought a change in the geometry of its front wing flap, in a bid to improve its performance in low balance.
Williams has brought new floor fences to improve flow conditioning, with Sauber bringing minor changes to its floor and front wing, as the Swiss squad hopes to continue its trajectory in the points.
Three teams have opted not to bring any revisions to Silverstone: Ferrari, Mercedes and Alpine.
The Scuderia has confirmed that there are no new upgrades after the plethora it brought to Austria last week, seemingly having played its hand for the time being at least.
Mercedes has brought nothing to the race, except hope of an upturn in fortunes after a disappointing showing in Austria last week.
And the Enstone-based squad have also opted to bring no upgrades, as it hopes to get back on the board after a torrid weekend at Spielberg.
