Williams have a plethora of new parts at the final pre-season test in Barcelona, as they look to extract further performance from the FW37.  Part of that upgrade package is a new set of airflow conditioners, which rather than simply being vertical elements now arch over to meet with the sidepods shoulder.  The airflow conditioners have also been splayed outward from their leading edge, something we have seen Red Bull do for some time now.  Their intent as ever is to protect the airflow that feeds around the sidepods undercut from the front wheel tyre wake, splaying them shows more surface area to the wake.  The added arch provides further protection to the flow over the sidepods from the upper tyre wake, increasing efficiency across the sidepod.  As the arch now falls on top of the previous vortex generators location (see below) a fresh vortex generator has been added slightly inbound of this (marked in yellow, above).
Several people have commented to me, that they couldn't understand why the Williams doesn't appear to have such a large undercut as some of its rivals.  This is true but only because their whole sidepod is narrower, if you look at the image above you'll see that the crash structure (standard across the grid) protrudes from the sidepod, looking like a blister.  This blister is retained with the new setup but no longer has the smaller connecting rod to the sidepod airflow conditioner.

Whilst I'm trying to keep atop of the blog you may have noticed of late that there is less content appearing. For those of you that haven't realised, most of my work has now been moved over to Motorsport.com where I'm working with Giorgio Piola.

I'm still doing the technical image gallery for each GP with the continued support of friend of the site Sutton Images. However, as always my time is limited and so this might not be updated as quickly as it once was, so keep checking back.

As some of you may have found out already I'm also working with the Missed Apex crew on their podcast from time-to-time, either doing race reviews or dedicated 'Tech Time' shows.

I've embedded the latest version of the podcast below and will update this a frequently as I appear. However, please head over to Itunes if you want it to appear in your player when episodes are available. The show is great to work on and has a great lineup of 'regulars' but has also enticed some bigger names recently too, with Will Buxton and Bradley Philpot on shows during the summer break.
