While both McLaren drivers had numerous updates on their MCL32s in Melbourne, Fernando Alonso was the only one to run the new front wing, partially explaining the delta to his teammate Stoffel Vandoorne.

The new front wing's mainplane features a full length slot [1], which makes the entire wing work harder allowing a different angle of attack.

This has allowed the designers to reduce the strakes under the wing, down from three to two [2], as they position the airflow as it makes its way around and across the front face of the tyre.

The footplate [3] has been tweaked and now features a much taller, shapely geometry, changing of the vortex formed within.

The flap geometry and chord height has also been revised with the tips [4] standing up much taller, revising the ferocity of the Y250 vortex.

Finally, the outer section of the wing stack has also been re-proportioned, giving more surface area to the the flap.

While Alonso ran the full upgrade package (below), including new bargeboards, sidepod vortex generators and a revised floor, Vandoorne did not, as the Belgian did not have the new bargeboards at his disposal either.
