The W05's Front Wing is a refined version of it's predecessor taking into account the loss in overall width (150mm or 75mm either side) the Main Cascade has been treated to an additional Vertical Strake to aid in turning the airflow around the upper outer quadrant of the tyre's shoulder. In the outer portion of the now split Cascade we see the team have once again installed an IR camera to assess the thermal properties of the front tyre. Added to the
Mercedes have taken a similar route to Ferrari in their adoption of a high chassis and step from the nose with a graduated rearward/inverted slope to the main section of the nose. However in order to gain more space between the Mainplane and Nose tip they have used the work around in the rules similar to that of Lotus who presented their Sabretooth before them. The nose has been made with 2 hanging pylons in order to meet the 185mm nose tip
height and 9000mm2 cross section at 50mm behind
the tip regulations, with one side longer than the other but the opposing shorter side flanked by a Vanity Panel. Slighty rearward of the noses hanging wider pylons we find the much narrower connecting pylons which arc backward to maximise space under the nose. Like Ferrari the team have utilised the mounting of the FOM cameras to glean a small aerodynamic advantage, arc'ing bodywork from the nose over to the mounting points. This adoption reminds me of the 'Elephant Ears' the team used back in the Honda days.
At the front of the Sidepod the inlet seems relatively small compared to the McLaren running the same Powerunit, whilst the team have chosen to run the same triangular cockpit strake ahead of the pod as last year. On top of the Sidepod we find two Vortex Generators with opposing designs looking to change the airflow in different ways. The Sidepod Airflow Conditioner is doglegged like last years design in order accentuate the Sidepods inlet profile and allow maximum airflow around toward the coke bottle. Cooling from the Sidepod is taken care of with an outlet ahead and inline with the Suspension pickup allowing space underneath for the airflow to cut around into the coke bottle..
The team have worked hard on maximising the undercut which allows a cleaner flow of air to the rest of the car, mounting the construction spars in a lent backward orientation encourages the airflow to pass over the engine cover aft of it.
Featuring a Shark Fin to meet with the dimensional regulations we also find a pair of outlets at the base of the fin which undoubtedly aid in the targeting of the exhaust gases exiting behind it.
Mounting the rear wing for all the teams this year has been a decision based process of strength over aero, the loss of the Beam Wing has meant that teams either make their Endplates more rigid or run with centralised mounting pylons. Mercedes have decided to go with the latter option and likely because they have decided to utilise serrations in the Endplates lower rear section. This is a departure for the team who have failed to follow the lead of other teams over the last few seasons in using Trailing Endplate Strakes. The team have retained the leading edge tyre wake slots they used on the W04 but have moved them much closer to the leading edge and run them much lower to the bottom of the Endplate. The catalyst for the move coming from the serrated/fanned trailing sections of the Endplate which will of course aid in creating upwash, something that will be sorely lost along with the Beam Wing.
The Diffuser seems to have a very thin U section in the central portion of the Diffuser which collates airflow from the upper surface of the floor ahead of it and uses it to enhance the Diffuser (Dare I say it very much akin to the DDD approach, but obviously no holes within the surface of the floor).
Ahead of the rear wheel we can see that Mercedes have retained the tyre squirt slot that the W04 ran but the Vertical Strake inbound of it has been straightened with it's predecessor having been arched.
Of course this an early look at the car and so any additional images/info that becomes available will be posted ASAP
