Red Bull RB11 front wing detail

Ferrari SF15-T sidepod airflow conditioner

Manor MR03B chassis detail

Ferrari SF15-T rear wing endplate
Ferrari SF15-T rear end detail, not new but note how Ferrari use the lower rear wishbone surrounds the halfshaft.  Its exposure is inline with the cooling outlet for which it is likely responsible of entraining that airflow.

Force India VJM08 front wing detail

Force India VJM08 with flo-viz applied to the rear wing, this is the specification they've been running for some time now and have a new wing in Mexico, as such they're validating their findings with a back-to-back run.

Lotus E23 with kiel probe array mounted to the front brake duct, measuring airflow around the front tyre

Force India VJM08 - Hulkenberg scrolls through settings on the steering wheel display (PCU-6D) at the end of the pitlane

McLaren MP4-30 with kiel probe array mounted on the sidepod

McLaren MP4-30 with an array mounted on the endplates from their Y100 winglet.  The array appears to be measuring the velocity / trajectory of the exhaust plume as the team continue to understand how to get the best from the energy it dissipates

Lotus E23 with flo-viz applied to the rear wing

Mercedes W06 steering wheel from behind
Lotus E23 with flo-viz applied to the rear wing and Y100 winglet, note the use of assymetric cooling again.

Red Bull RB11 from behind, note the increased cooling

Mercedes W06 with flo-viz applied to the rear wing

Mercedes W06 pitot tube / kiel probe mounted to the front wing of the car to validate findings on the nose selection (Mercedes have a couple of designs which feature different underbellys)
Force India VJM08 rear wing - changes made to the centre of the mainplane, with the leading edges geometry changed (highlighted in green), the upper flap has also been changed, with the central portion now twisted outward rather than being bowed inward which has also led to the central 'V' groove being made shallower (highlighted in light blue).  Meanwhile at the outer edge the fixed profiles (highlighted in purple) that form part of the endplate and act as an extension of the flaps, have been increased in number, creating slots for the high pressure airflow to move into the low pressure region, changing the way the tip vortex forms.  For additonal balance the team have also utilised a Y100 winglet (tested way back in Austria) which will help with the transition as the car goes from the high speed straight to low speed corners.
Force India VJM08 front brake duct, note how the lower fin (green) has been changed, rather than the curved fin which was mounted on the vertical brake duct wall the team have added two horizontal mounting fins and enlarged/reshaped the fin (green).  The intent of this fin is to control how airflow is shed from the front wing and tyre.
Toro Rosso STR10 front brake ducts, clearly struggling with the low air density and temperatures at altitude the team had to revise their front brake ducts.  Like McLaren they ordinarily use a splayed finger style scoopless arrangement (inset) but had to hurriedly rectify the design when more cooling was required.  The team have likely 3D printed these small sections (green) on site and have then cut and shut them into the original components
