New rear wing for Red Bull
Red Bull have used the Malaysian test last week to improve their aerodynamic package, resulting in a new rear wing. The lower image shows the wing that was used by both Toro Rosso and Red Bull Racing in Australia. The new wing is not curved up anymore in the middle but instead has a dropping leading edge all over the span of the wing, except for both ends where they are a bit cut off. As seen with other teams too, the trailing edge of the upper element has been cut off towards the end plates. Meanwhile, Red Bull has also switched back from its wide Ferrari-alike mirrors while Toro Rosso is still using them.
An excellent and effective addition to the Red Bull cars, Note also the RBR-Renaults were running new side-pod shields.
These changes could just be to show the cars arent identical. Who knows?
