Welcome

I'm Matthew Somerfield, a freelance journalist focused on the technical elements of Formula One. It has been a pleasure to provide content via this site for the last 5 years, which has led me to several paid freelancing jobs along the way. I'm currently plying my trade with Motorsport.com and working alongside the legend that is Giorgio Piola.

This has seen the content here diminish as a result and I'd like that to change. In order to accomplish this I need your financial support, as I need to break free of the shackles of doing this part time. If you like the content I've been producing and want more of it I'd ask that if you can spare some change each month it'd go a long way towards transforming this site into the technical behemoth I know it can be.

As such I've set up a 'tip jar' over on Patreon and will continue to set goals and rewards based on our success - www.patreon.com/SomersF1

Mercedes introduced a new rear wing at the second pre-season test, the design of which retained a similar layout to its predecessor, although the aim is of course to make the overall structure more efficient.
You'll note that where the team had previously used two support pylons (left, yellow), there is now only a singular inverted Y-Lon (right, yellow), providing additional rigidity. This design change has also led to them reducing the aligned slot gap separators (yellow) to singular element to match the pylon change. The top flap which previously featured two V grooves, for drag reduction, has also been altered, reducing the V grooves to a larger, singular item.

The rear wing endplates have also seen a small revision, with the serrations extruded upward, in order to further maximise the upwash effect they're generating.

Mercedes used perhaps the largest and most outwardly complex Y100 winglet (Monkey Seat) on the grid in 2014 (below), with the exception of the specification they used in Monza. It is a surprise therefore to see the team using a similar specification to the Monza one throughout the test (Green), indicating the team have either taken another direction or are making gains elsewhere.

  1. About the small Y100 winglet. I was watching Peter Windsor talking about the test yesterday. Apparently the more complex Y100 wing came off while Lewis was on track. Maybe that's why they where running the smaller winglet.
