Australian Grand Prix: Digging into the details…

An overview of the front suspension, deflector array and sidepod corner on the Mercedes W17, with the small cooling louvre panel on the upper surface of the sidepod also to be noted.
Red Bull RB22 deflector array
For comparison, a similar angle of the Red Bull RB22, showing their front suspension, deflector array and sidepod arrangement.
McLaren MCL40 front wing and nose from the side
A side view of the McLaren MCL40’s slender and elongated nose tip, with the actuator rods for their active aero also visible as they protrude out the side of the nose. Also note the tyre sensor has been incorporated into the trailing edge of the front wing’s diveplane.
Haas VF-26 front wing detail (front)
Haas have gone a different way to most of their rivals with the design of their footplate, with a squared-off profile creating a ridgeline over the surfaces’ back. Meanwhile, the tyre sensor and pod sits on top of their diveplane.
