The lower winglets (blue arrow) on the F2008's nose were introduced at June's French Grand Prix, but their width and positioning have changed over the past few months, depending on the front-wing flap used by the team. And in China, narrower winglets (inset and yellow arrows) were adopted because,...
As in Belgium, in China the cross-sectional area of the McLaren's sidepod inlets was reduced, decreasing cooling capacity but increasing aero efficiency. At Spa the low ambient temperatures made this change feasible. In Shanghai it was possible - albeit to a slightly lesser degree - thanks to the...
BMW Sauber have adopted a revised front wing assembly for the Japan and China races. The wing's main profile features a new lip, which protrudes to the rear. Visible thanks to its natural carbon fibre colour, this lip extends about 20mm under the flap entry edge (see yellow arrow and inset)....
Ferrari has replaced the vertical fin (blue arrow) that connects the winglets in front of the sidepods to the rear edge of the barge boards with a heavily curved one. This results in less disruption of the airflow passing close to the winglet, dramatically reducing turbulence and generally providing...
The central side section of the diffuser (circled) has been made narrower, with its reduced horizontal base now ending with a vertical fin. In turn, the Gurney tab (in yellow) along the main exit edge of the diffuser has been extended towards the centre of the car. This change is to reduce the...
