Honda RA106 - cockpit 'ears' and turning-vane fin 06 May 2006
An interesting change for Europe is the addition of these unusual fins, or 'ears', (1) just in front of the Honda's cockpit. They extend as far back as the mirrors and are designed to better manage the airflow close to the chassis. They help to cleanly separate the upper airflow (passing over the car) from the lower airflow going into the sidepods to provide cooling. Another new detail is on the turning vanes, which now feature a triangular, vertical fin (2). This is another device to cut turbulence and hence enhance the aerodynamic efficiency of the bottom of the car.
