Mercedes-Benz F1 W08 rear wing 3 / 20 Photo by: Sutton Images Mercedes returns to using a ‘spoon-style’ rear wing in Canada, focusing its efforts on the demands of the medium-downforce circuit.

Williams FW40, brake detail 5 / 20 Photo by: Giorgio Piola Williams is utilising a revised brake duct, complete with an amended shape to the vertical fence and the introduction of an external inlet scoop. These changes will increase the cooling capacity of the brakes as more air can now be drawn in.

Ferrari SF70H, rear wing 7 / 20 Photo by: Giorgio Piola Ferrari has chosen to introduce a new rear wing in Canada to better suit the demands of the medium-downforce circuit. The design features a swooping spoon-style mainplane and top flap, while the endplates feature the open-ended style louvres we’ve seen adopted by most of the teams so far this season. Ferrari has also returned to a more simplistic single-element T-wing, abandoning the twin element one introduced in Spain. The team also returned to the pre-Monaco exhaust-wrapping monkey seat.

Downstream of this is the much talked about scythe-shaped slotted floor section which was seen to flap around at high speed at the opening few races.

It helps with the transfer of heat from the brakes to the wheel rims and, in turn, the tyres.
