Turn 13 at Indianapolis is the only real banked turn in Formula One racing and proved Michelin's undoing. With an angle of up to nine degrees, it demands a left-right compromise on suspension set-up. The left tyres take the heaviest strain, particularly their shoulders, with tyre temperature...
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...
A completely new design for the US. The upper profile and flap feature a dished, V shape, which has proved more efficient in terms of top speed in testing, at the same time maintaining clean and efficient airflow at exit, so as to help with air extraction from the rear diffuser. New endplates sport...
This revised design is intended to reduce drag on the fast sections of the Indianapolis Motor Speedway. It features a narrower flap with a diagonal top profile (red arrow), reducing the cross section of the element (and hence drag) as much as possible. Single-lap performance has looked good -...
A revised flap for the US (right arrow), without the pointed extension (left arrow) seen in the recent races. Indy set-ups usually favour the track's high-speed section and this change indeed lessens drag and downforce. The lower section of the endplates are also newly rounded towards the rear to...
The FW27's aerodynamics never stop evolving. For the US the rear of the sidepods have received particular attention, with interesting double winglets, the lower smaller winglet connected to the sidepod by a short horizontal link (left red arrow). This change is coupled with revised exhaust chimneys...
