The Mercedes AMG W03 Formula 1 car that ran Tuesday at Magny-Cours during the young driver test featured a heavily revised exhausts layout.

The Ross Brawn team has modified the W03 by fitting side exiting exhausts to blow the diffuser area. These exhauts use what is called the Coandă effect to force the exhaust plume back down from the higher tailpipe. The Coandă effect is the tendency of a fluid jet to be attracted to a nearby surface.

The Coandă effect will now direct the burning exhaust plume down towards the edge of the diffuser, even at relatively low speed. This helps to both speed up airflow under the floor and to seal the diffuser from airflow entering from the sides, which increases low pressure below the floor for more downforce.

On the photos, we can see that the Mercedes engineers were monitoring variations in air pressure with racks of Pitot tubes located on each side of the rear wing, underneath the main plane of the rear wing and under the diffuser.
