Ferrari introduced new front turning vanes and a new rear wing on Friday in Melbourne, but only on Felipe Massa's car. It was added to Kimi Raikkonen's on Saturday, though he didn't get much practice running with it thanks to his hydraulic problems. Both men qualified and will race with the new package. For the first time, the rear wing has a slot (red arrow) in the middle of its main plain (a solution introduced by Toyota two years ago) to increase downforce. The endplates are those introduced at the recent Barcelona test.
Williams FW31 - revised nosecone splitter
Williams have brought to Melbourne a modified version of the nosecone splitter (see red arrow) first seen during pre-season testing at Barcelona. Positioned low down on the nosecone, the revised part better directs the airflow through the lower part of the car to feed the diffuser's central section. Note the wing-like shape of the mini vertical turning vane's leading edge.
Brawn BGP001 - front-wing design
As well as its controversial diffuser design, the Brawn also features a very innovative front wing. Situated very low at the front, the wing boasts sophisticated endplates (1), divided into two sections to better direct the airflow (purple arrows). An inventive horizontal splitter (2) creates a kind of venturi effect under the chassis, while the steering arm (3) has been located level with the lower wishbone to lower the centre of gravity. The engineers have also added a small spoiler (4) to each side of the nose cone.
