Red Bull RB11 - New rear suspension uprights

Red Bull presented their new car in a special 'camouflage' livery, but it couldn't conceal an interesting update to the suspension uprights...

Suspension arms and their attachments to the upright are becoming more and more integral to an F1 car's aero package, and nowhere is this more evident than on Red Bull's new RB11.

On the team's 2015 machine, the plate to fix the top wishbone to the upright is not only wider, it also has a plane profile to work in synergy with the rear brake duct. As the image shows, this helps improve airflow around the rear tyres (blue arrows), whilst the brake duct itself aids the extraction of the hot air from the brakes (red arrows).
