"The margins at the front remain extremely tight," McLaren technical director Neil Houldey said, as the team prepares to introduce a new, revolutionary rotating rear wing, the "H-Wing", at the Italian Grand Prix. It is a technological answer to the similar designs already run by Ferrari and Red Bull. Yet Monza is unforgiving. The long straights demand minimal drag, while the heavy braking zones demand maximum stability, leaving the team facing an engineering paradox. Named in honour of the Etihad Airways partnership, the wing carries on the inventive spirit of the legendary 2010 F-duct and is meant to become a genuine aerodynamic weapon on the Monza asphalt. It is this risky innovation that will decide whether the British team can seize the lead and leave its rivals behind for good.
