Technically Formula 1 - Jerez Testing Day 3

Technical innovation is what makes Formula 1 so different from any other form of racing. The on track action is as much played out by the engineers and aerodynamicists as it is the drivers. We are here to admire, study, and discuss this beauty that exists on the ragged edge of what we think is possible, or at least what we thought was possible. Be sure to check out Jerez Testing Day 1 and Day 2.

Discussions and questions are welcomed and encouraged in the comments section below.

More pitot tubes mounted on top of the rear wing. That pod glued to the rear wing endplate is temporary, along with the pitot tubes, and most likely houses some sort of computer or transfer device.

Toro Rosso getting crazy with the flow vis again...

Marussia

Note the inlet duct on the shark fin of the Marrusia chassis, along with the air scoop that is separated into 3 inlets. The MR03 also features an air scoop without any stand-alone supports.

CT05 diffuser detail. Modeling air in a wind tunnel does not always accuately represent the airflow on a race track, so teams must work with this special flow vis paint to try and understand how the air is flowing round the chassis.
