Formula 1 teams have confirmed the details of the changes they have made to their cars for this weekend’s Spanish Grand Prix.
Here are the changes each team has informed the FIA about. Haas is the only team which say they have not introduced any upgrades to their cars this weekend.
Mercedes
Front Wing Endplate
Reason for change: Performance – flow conditioning
Difference: “Change in endplate camber.”
Description: “This change in endplate camber, which curves gently inboard, is designed to improve flow on to the front cake tin deflector, and hence flow to the rear of the car.”
Floor Edge
Reason for change: Performance – flow conditioning
Difference: “Slot added to outer edge of floor.”
Description: “This is a detail change similar to that found on other cars, and it is designed to improve floor performance when it is running close to the ground.”
Rear Corner
Reason for change: Performance – flow conditioning
Difference: “New lower deflector endplate.”
Description: “This modification generates increased local load on the lower deflector inside the rear wheels, which in turn increases overall diffuser load.”
Floor Body
Reason for change: Performance – local load
Difference: “New bib vane added to keel.”
Description: “The new bib vane has a dual function and benefit: first, it generates local load in the middle of the car; second, it sends a vortex under the main floor of the car.”

Front Wing
Reason for change: Circuit specific – balance range
Difference: “A new flap has been designed with locally longer chord profiles more camber angles and increased angles of incidence.”
Description: “More front wing load is generated on all the profiles as a consequence of the new design of the flap profiles.”
