Toyota rear wing philosophy

Many of the fans and engineers have noticed that the Toyota of this year looks a bit unconventional in a way that it looks quite boxy and that there are lots of small winglets added all over the car. While this was reduced by their new front wing introduced in Turkey, the rear wing is still very much different from any other one. The most important difference is the deep mean camber of the wing. The leading egde actually forces air down towards the lowest point of the wing. This design option is visible when looking at the Panasonic banner on the wing, which is hardly visible, while the front surface of the wing at Williams (lower part of the image) can be read completely.
