From FP3 onwards in Baku, the team went to a balanced brake duct configuration.
The team trimmed its front wing's upper flap significantly in Baku in order to balance it with the lower-downforce rear wing being used.
Mercedes trialled this lower-downforce spoon-style rear wing in Baku before reverting to a higher-downforce configuration.
The higher-downforce rear wing raced by the team in Baku.
Having introduced its nose cape in Spain, Mercedes made an optimisation in Austria, placing a slot a few centimetres from the trailing edge and upturning the latter section.
A look at the L-shaped vane mounted to the side of the crash structure that the team added in Austria (red arrow), along with the smaller blade-style winglets added either side of the structure (yellow arrow).
Mercedes revised its wing mirror and stalk design in Austria, placing the stalk further inboard (arrowed).

The floor unmounted from the car shows the detail around its front edge, including the bargeboards.
A look at the nose and the ‘cape’ solution used by Mercedes.

The team used a cut-down upper flap on the front wing in Belgium (arrowed), while introducing a slot in the rearward section of the nose ‘cape’.
A close-up of the front wing endplate shows the level of detail used at the rear of the surface in order to turn flow outboard.
The W08’s front brake assembly without the brake drum attached shows the complexity of the pipework that feeds various components, such as the disc and caliper. Also note how the mechanics have used silver tape to blank one of the openings to reduce cooling.
The car during build-up, showing off many of the details that normally lie hidden beneath the bodywork.
The low-downforce, single-use rear wing favoured by Mercedes at Monza features a low angle of attack and just three endplate louvres to disperse the tip vortex.
