Ferrari SF90, rear suspension 4 / 15 Photo by: Giorgio Piola The area around the rear tyre has been developed heavily by teams in recent history and as we can see from Ferrari that means a plethora of slots and winglets are being used to control how the airflow spilt off the rear tyre impinges on the flow around the rear coke bottle and into the diffuser. In the case of Ferrari, it’s interesting to see the slot in the floor to the left of the vertical strake.

Racing Point RP19 6 / 15 Photo by: Giorgio Piola The large torpedo-shaped appendage on the side of the RP19 encloses a thermal-imaging cameras that monitors the tyre’s behaviour during Free Practice, giving the engineers vital data to work with for qualifying and the race. It’s shaped like this in order to limit the aerodynamic impact it has on other areas of the car.

Red Bull Racing RB15, side 8 / 15 Photo by: Giorgio Piola Cooling performance is paramount in the rarified air at the Mexican GP, so Red Bull has opened up some cooling in the transition around the halo.

Red Bull Racing RB15, rear 9 / 15 Photo by: Giorgio Piola At the rear of the car Red Bull has opted for the largest cooling outlet of the season so far, with exits also opened up around the suspension’s upper wishbones.

Williams Racing FW42, front wing 11 / 15 Photo by: Giorgio Piola A side-by-side of the two front wings used by Williams in Japan and to be tested once more in Mexico. The new wing on the left is proportioned differently in terms of the upper flaps, with less real estate afforded to the adjustable section.
