A particular shark fin on the Force India

Force India is clearly not standing still after their recent successes at Spa and Monza. At Singapore, the team introduced a shark fin, replacing the car's conventional engine cover used throughout the season so far.

The new fin connects to the rear wing, just like at Red Bull, although Force India's version features a large opening ahead of the rear wing to control its unfluence when the car is under yaw. The change immediately appears to have made the stacked centre of the rear wing obsolete, an item that was used at Valencia to increase downforce.
