Cited upside down on the chassis we get the opportunity to see the clutch paddle arrangement favoured by Fernando Alonso, which uses a socket style adaptation in order that his fingers reside within the paddle and get a better feel for the clutch movement.

McLaren was one of the most active teams when it came to front wing optimisation throughout 2017 and kicked off their campaign with 5 changes to the front wing in Australia.
1 - an extra slot in the mainplane, 2 - two strakes running underneath the wing, rather than three, 3 - a revised footplate arc, 4 - revised shaping to the flap tips and 5 - a revised outer flap configuration.

Optimising flow around the sidepods the team made several revisions in Australia, with the upper surface of the bargeboard connecting winglet revised (red arrow), three vortex generators placed on the sidepods shoulder, rather than one (white arrow) and an extra axehead added to the floor (blue arrows).

McLaren introduced a long floor slot in China, similar to one already seen on the Toro Rosso, improving flow along the cars flank. The red arrow points to an almost imperceptible slot placed midway along the floor that ensures its compliance with the regulations.

The team introduced a T-wing in China, dubbed a ‘coat-hanger’ style due to its appearance. The winglet sought to generate its own downforce while also improving the behaviour of the rear wing, primarily through manipulation of the tip vortex. The complexity of the rear wing endplates is also drawn to your attention with the arrow.

Changes made to the already complex rear wing endplates on the MCL32 include a much longer pair of slots toward the rear of the surface and a revised leading edge (arrowed, left inset).

The diffuser was updated in Spain to feature this vertical slot in the outer edge, injecting some of the high pressure flow from the upper surface into the outer section of the diffuser, affecting the edge vortex.

The bargeboards were a source of constant development throughout the season, with the slots in the footplate (arrowed) continually optimised.

This top down view of the MCL32 with Jenson Button at the wheel affords us a great viewpoint of the aero surfaces at the front of the car. Note also the use of asymmetric cooling panels beside the driver, with eight louvres in the right panel and none in the left.

McLaren joined a growing pool of teams to employ rearward facing gurney extensions that reach back behind the diffuser, with the intent of revising the edge vortex.

Kiel probe arrays are mounted ahead of the sidepods as the team looks to gather data on the airflows movement around the midriff of the car, with updates to the bargeboards and surrounding aerodynamic paraphernalia made in Monaco.

In order to help quell the effects of ‘tyre squirt’ the team added three slots into the floor ahead of the rear tyre.

A revised cascade layout was introduced in Austria, featuring its own mounting support next to the main endplate and revised geometries to the outer, vertical fences.
Hungarian GP

The front wing in Hungary utilised a gurney trim on the uppermost flap in order to add a little more front end and balance it with the gains made at the rear of the car.

An all too familiar sight in 2017 as the RA617H Honda power unit is detached from the MCL32 for investigative work. In doing so though, it gives us an opportunity to see the installation.

The MCL32’s front brake duct assembly utilises a sizeable ‘crossover’ pipe which draws air in through the main brake scoop with the intent of ejecting it through the wheel face.

The MCL32’s rear brake duct assembly manages the temperature relationship between the brakes and the rear wheel rims. Also note the significant quantity of winglets mounted on the inside of the vertical fence.
