Contrary to expectations, Mercedes has not implemented any changes on its W13 Silver Arrow for this weekend's Australian Grand Prix while its Red Bull and Ferrari rivals have added a few changes.
Mercedes' struggles in the first two races of the season triggered the expectation that the Brackley squad would head to Melbourne with new parts in its crates, but the German outfit's car is unchanged since Jeddah and features the exact same rear wing.
However, front runners Red Bull and Ferrari have added a few revised elements to their car.
The Milton Keynes-based outfit's RB18 featured a modified front wing endplate during Friday's "show and tell" pitlane exhibit.
Over at Ferrari, the Scuderia's F1-75 includes a tweaked diffuser designed to spread the airflow more evenly across the rear section of the car.
Assessing the changes down the field, McLaren has added a flow-conditioning winglet at the rear corner of its MCL36, while Aston martin's AMR22 features a new rear wing.
At Alpine, the Enstone squad's A522 features new floor fences and a modified rear brake drum while Williams' FW43 sported a new beam wing.
Haas will trial an upgraded diffuser on its VF-22, but Alfa Romeo and AlphaTauri, like Mercedes, have not brought any upgrades to their contenders in Australia.
