Mercedes has promised a significant and visible upgrade package for their car at the British Grand Prix, and now they have detailed all of the changes.

Judging by the comments coming from Mercedes, it appears that the British Grand Prix will be a key event when it comes to the development of their 2022 car.

Ahead of the race weekend, the team revealed the upgrades they brought to Silverstone:

Front Suspension

Reason for change: Performance – flow conditioning

Difference: “Volume added to side of chassis local to pushrod and [front top wish bone] rear leg, along with fillet extensions where these legs meet the chassis.”

Description: “Downwashes the flow local to the chassis side, shedding a vortex which then goes on to improve the flow underneath the floor.”

Sidepod Inlet

Reason for change: Performance – flow conditioning

Difference: “Repositioned vanes on side of chassis ahead of sidepod.”

Description: “Improves flow alignment of these vanes, which in turn improves flow quality into the radiator duct and hence also cooling performance.”

Floor Body

Reason for change: Performance – local load

Difference: “Increased floor edge wing slot forward and increased camber of forward portion.”

Description: “Increased camber drops pressure locally to increase floor edge loading, this in turn increases forward floor load.”

Rear Wing

Reason for change: Performance – drag reduction

Difference: “Reprofiled wing tip (reduced camber).”

Description: “Aim to reduce wing load efficiently; this has been applied to our medium downforce wing and is track-specific.”



Floor Body

Reason for change: Performance – flow conditioning

Difference: “Realigned bib wing [angle of attack].”

Description: “Generates local load – the update was to improve flow alignment and hence improve flow quality under the floor.”

Floor Body

Reason for change: Performance – local load

Difference: “Small camber change to forward floor fence.”

Description: “Increases the pressure delta across the fence, which increases local floor load and also improves the flow to the diffuser.”
