Ferrari Winter Testing Upgrades Report


Ferrari was one of the first teams to introduce their major upgrade. On the second day of the second test in Barcelona, once the rain had stopped we saw part of the upgrade package, as some more parts were tested in the last day of the test and the rest of the parts will be tested tomorrow Friday 15/03/2013 during free practise of the Australian GP.
  
While the concept did not change, the new sidepods now bend down more. As a result the coanda ramp is now lower to better aim the exhaust plume towards the diffuser’s edge.

As well as a changed coanda ramp, the cooling outlets have changed.  In the following drawings I have moved the suspension and rear wing so that you can see what has changed more easily.

New Cooling Outlets

The new version sports wider cooling outlets just behind the exhaust and coanda ramp while in the older version they were slimmer. However, in the original version which is very similar to the one present on the F2012, there was a second cooling outlet further back which also featured two cut-outs on each side. The second cooling outlet has now been removed, thus the need for the wider outlets behind the exhaust.

 The new front wing was briefly seen on the second day of testing and brought back for the last day.

This new front wing adds yet another element on its outer tips, together with new cascade wings, endplates and the adjustable upper element.

 The new element on the outer tips, allows the wing to curve outwards at a larger angle to create more downforce and direct a larger portion of the airflow around the wheels.
The new endplate is covering up a portion of the open area that allowed airflow flowing over the top of the wing to flow to the outside. This will create more downforce. As well as the new endplate, the footplate now features a slot which is an innovation by Ferrari it is the first time seen on a car, ever.

 The new cascade element is no longer divided into two different parts, instead it is one winglet only much wider than before. The fence that divided the two cascade elements on the older version has now become a vertical fence which will induce a stronger vortex in the attempt two direct the airflow around the front wheels as efficiently as possible.
At the top of the endplate a smaller winglet has been added, similar to the one used by Red Bull. 

The inner adjustable element of the wing has been revised, with its inner extremities now taller than before.

Moving slightly upwards, we will find the new strake running along the sides of the nose that was first introduced in the last day of the first Barcelona test but was slightly revised in the second one. The strakes are there for legality purposes, so they were tested before Melbourne.


On the last day of testing, the team tested more new parts. On of which was the new rear wing. The wing now features smaller v-cutouts on the top of the upper element. In addition, the endplate has been revised and the gills are now slightly smaller than before. Those gills bleed the high pressure air from the inside of the wing to the outside, reducing drag by weakening the strength of the vortex shed at the wing tips.


The last new part tested was a new diffuser which still features the airfoil shaped gurney flap on top of the diffuser’s trailing edge, but it now curves downwards instead of stopping at the edges. Also, the diffuser no longer dips down where the two main vertical strakes are located.

  1. Hi, great and informative, as ever.

    Ferrari already changed the Engine cover extending it to the diffuser as 1st day of Melbourne Practice, anything about that?

    1. It is a minor change. It is now slightly wider. Lets wait and see if it will be used. It could be the engine cover for hot races, like Malaysia which is just next week and the parts will be flown to Malaysia next.
