Red Bull RB11 - S-duct

For 2015 Red Bull have retained the nosecone S-duct introduced two years ago, following the trend set by Sauber...

The duct allows airflow to pass from the underside to the top of the chassis. As you can see in the comparison with last year’s layout (small inset), the duct on the RB11 has a more compact and sophisticated shape. Also different as a result is the position of the brake master cylinder inside the chassis.
