Formula 1 goes racing at Silverstone this weekend for Round 9 of the season, an event that will also see the Sprint make its return. Several teams are set to run upgrades at the British Grand Prix \u2013 but what parts are each squad planning to use? F1.com has rounded up all of the details\u2026<\/p>\n
Mercedes<\/p>\n
After sporting a couple of updates one week ago in Austria, Mercedes<\/a> have opted not to bring any new parts to this weekend\u2019s event.<\/p>\n Ferrari<\/p>\n Ferrari<\/a> are using an updated rear corner at Silverstone. The increased cooling inlet and outlet sections, updated lower deflector and re-optimised rearward winglet cluster are all aimed at improving performance in local load and cooling.<\/p>\n McLaren<\/p>\n Of the front-running teams, McLaren<\/a> lead the way in terms of updates this weekend. The reigning champions\u2019 upgrades list features changes to the front corner and floor furniture, with the former seeing a new front brake duct introduced \u2013 which the team are hoping will result in \u201cimproved flow conditioning and gain in aerodynamic load\u201d \u2013 while a revised floor board in the latter is aimed at improving flow physics and a gain in overall efficiency.<\/p>\n Red Bull<\/p>\n Red Bull<\/a> delivered a particularly significant upgrade package for their home event in Austria, but the team are bringing only one update this time around \u2013 that being an updated rear corner, with the cascade wings in the rear wheel bodywork winglets being revised to \u201cimprove the load characteristics and stability\u201d.<\/p>\n Alpine<\/p>\n No updates have been submitted by Alpine<\/a> at Silverstone.<\/p>\n Racing Bulls<\/p>\n An updated floor corner and diffuser geometry has been introduced at Racing Bulls<\/a>, the target being to \u201cgenerate more load and provide increased performance\u201d. There will also be a new forward deflector geometry on the rear corner, aimed at improving local flow conditioning and floor performance.<\/p>\n Haas<\/p>\n Haas<\/a>\u2019 Ollie Bearman<\/a> recently suggested that the squad have been \u201cout-developed\u201d by their rivals<\/a> \u2013 so the team will be hoping for a boost from their two upgrades this weekend. The rear wing profiles have been \u201ccomprehensively revised\u201d, they have said, with the aim being to improve performance in local load. The rear wing endplates have also been refined with the introduction of external protrusions, targeting better flow conditioning.<\/p>\n Williams<\/p>\n Williams<\/a> are bringing a new front wing geometry for their home race. This will feature updated profiles and endplate surfaces, aiming to \u201cgenerate an increase in local loading combined with an improved flow field interaction with downstream components\u201d.<\/p>\n Audi<\/p>\n There are no upgrades listed for Audi<\/a> at Silverstone.<\/p>\n Aston Martin<\/p>\n As is now well known, Aston Martin<\/a> are planning to bring a big upgrade package to the Hungarian Grand Prix<\/a>, meaning that there will be no changes for the local team this weekend.<\/p>\n Cadillac<\/p>\n
