Bite Size Tech: Force India VJM07 - New Rear Wing - China

Force India took the opportunity at the post Bahrain GP in-season test to assess a new rear wing that the team adopted for the Chinese GP. It's an all new design that features 4 core changes:

1. The rear wing mounting pylons have been reshaped, utilising a pear shape around the exhaust exit, similar to Ferrari and Sauber.

2. New rear wing endplates that feature longitudinal triangular strikes on the trailing edge, shaped upward that help to collate the pressure gradient and vorticise it, extrapolating some additional performance not only from the endplates but also the surrounding components via upwash.

3. The endplates also feature a new set of louvres (now horizontal) which change the way in which the airflow moves between each side of the Endplate and therefore how it affects the drag induced by the wing elements.

4. The rear wing also features a new mainplane and top flap, with only one slot gap separator running along the centreline rather than the two equidistant ones either side of the centreline on the old configuration.
