Williams FW28 - barge boards and ears 07 October 2006
For Japan, a tiny vertical turning vane (yellow arrow) has been added parallel to the side of the splitter's foremost section. Both elements connect to the front barge boards and help improve the quality of airflow directed to the bottom of the car. This generates additional downforce and helps reduce pitch sensitivity. Related in function are the Renault-style ears on top of the chassis (yellow circle), first introduced in China last week. These reduce vibrations at the front end and split the airflow directed to the rear of the car in two, cutting turbulence and improving airflow quality, to the benefit of cooling and rear-wing efficiency.
