McLaren MP4-22 - front cockpit 'ears' 16 March 2007

Since the last Bahrain test session, two winglets have been added to the side of the front section of the chassis. Last season similar additions were used by Renault in a few races. These elements don't noticeably increase the downforce, instead they act as turning vanes, splitting the airflow directed towards the cockpit. They work in conjunction with the horn wings placed behind the cockpit and raise the quality of the airflow directed to the rear end of the car, hence improving overall aero efficiency.
