Mercedes lists and explains upgrades for the W15 that the team has introduced ahead of the 2024 Emilia Romagna Grand Prix.
Floor Fences
Reason: Performance – Flow Conditioning
Differences: Small modification to fence alignment.
Brief description: Improves flow quality to the rear of the floor, which in turn improves diffuser and rear load throughout the ride height range.
Floor Body
Reason: Performance – Local Load
Differences: Modification to the floor tunnel volume.
Brief description: The tunnel volume change alters the trajectory of the fence and floor edge vortex systems, the result being increased local load.

Rear Wing
Reason: Circuit specific – Drag Range
Differences: Modification to upper wing tip shedding detail.
Brief description: Increasing the length of the flap tip shedding edge results in more local load and upper wing efficiency suited to this circuit.
Beam Wing
Reason: Circuit specific – Drag Range
Differences: New biplane beam wing.
Brief description: Biplaning the beam wing improves its local efficiency and also how it interacts with the upper wing and the diffuser.
Front Corner
Reason: Circuit specific – Cooling Range
Differences: Improved internal brake ducting.
Brief description: Improved design of the internal duct feeding the front brake disc resulting in reduced pressure drop and increased mass flow.
