Jordan EJ15 - double splitter 19 June 2005
Not entirely new, but an interesting feature at Indy. Just in front of the main splitter beneath the cockpit is an extra series of low barge boards (red arrow) with an almost V-shaped diverging profile joined by a horizontal plate. These elements work together with the horizontal turning vanes in front of the sidepods and the vertical sculpted shields at front-suspension level. They help manage airflow under the car, increasing downforce generated by the bottom of the car.
