Mercedes arrive at Monza clearly ahead of their counterparts, this hasn't stopped the team from introducing new components though, with a change made to their wing mirror mounts and the cockpit fin that sits alongside.
The new mirror stalks are mounted on the side of the cockpit when compared with their older design (below) that was mounted on the top edge.
This means that the stalk is shaped to interact with the fin placed alongside it which is also reshaped.  Previously the fin was triangular whilst the new fin is more of a rhomboid shape, this will of course have an effect on how it reacts with the stalk and the type of vortices that are shed.

The appendages that proliferate the area around the sidepods leading edge are critical to the behavior of the sidepod, determining how the sidepod reacts and at what speed.  It's therefore altogether plausible that these changes could be Monza specific, with a premium placed on drag reduction and top speed, meaning this new configuration is able to delay separation/ reduce boundary layer build up at the tail end of the sidepod.

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 where I'm working with Giorgio Piola.

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.
