BMW Sauber are the first team to introduce their own version of McLaren's innovative F-duct system, the speed of introduction helped by the fact that they had already tried using a critical part of this solution - a rear wing with a slot in it - at last years Singapore race. That slot effectively creates a three-element rear wing. However, there are notable differences compared to the McLaren system. The air directs on to the main section of the wing (longer blue arrow and yellow highlighted area), not the flap, whilst the 'F-duct' itself (smaller blue arrow) is positioned on the sidepods, not on top of the chassis like on the McLaren.
Renault R30 - modified front wing endplates
Renault have modified the front wing they introduced in Bahrain for the Australian Grand Prix. The new version (left drawing) features a different version of the top flaps small endplate. As well as being smaller, it has also been reshaped, and is now wing shaped rather than square in profile as previously (right drawing). Robert Kubica tested this solution during Friday practice and both he and team mate Vitaly Petrov ran it during Melbourne's qualifying and race.
Ferrari F10 - revised front wing
Ferrari have introduced a new aero package for the F10 in Melbourne. The new front wing has notably different endplates. The outer small turning vanes are now more straight (1) and lower, while the endplate itself is more curved towards the outside (3) at the rear to better direct airflow away from the front tyres. With this new shape, the vertical gurney flap (2) has been reduced.
