Mercedes MGP W01 - pyramid-shaped roll structure 23 February 2010

A new solution on the Mercedes is this pyramid-shaped roll structure, which acts as an aero splitter within the airbox, separating and accelerating the incoming airflow (double blue arrow). Usually the roll structure simply follows the shape of the airbox, but Mercedes' design means the shape of the airbox can be altered independantly, avoiding the need for a new crash test, should changes be deemed necessary over the course of the season. The single blue arrow indicates a second air duct, while the red arrow shows the mandatory hole that all cars must have in order to be able to crane them off the circuit in the event of an accident.
