Just like every other team on the grid, Red Bull (upside of image) and Toro Rosso (downside) have also developed a special rear wing for this event. The lower side of the new wing is similar to the Renault rear wing at the beginning of the season in such that it is at its highest in the middle part of the car. This wing is a clear example of development exchange between the two Red Bull(ish) teams. The complete wing as well as the end plates are identical on both cars. The winglets ... Read more
