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.


20 Sep 2014

If you've been hiding under a rock this season you won't have realised that Mercedes have barely used their 8th gear.  Unlike previous seasons the 2014 regulations only permit ratio's to be changed once in a season (a joker as we refer to it) in order to save costs.  Mercedes were the only team to run an exceptionally long 8th gear, meaning that their drivers rarely used 8th, and in all honesty its effectiveness would be stifled by a large power drop off when it was used anyway.  The idea of course was to spread the immense torque generated by the 2014 powerunits, reducing the chance of wheelspin whilst retaining the optimum gears througout the corners.

In the last few races other teams have played their own jokers, having had time to maximise the powerunit to their chassis package, and in keeping with the circuit characteristics remaining this season.  With this in mind both Mercedes drivers played their joker this weekend in Singapore (below an excerpt from document no4) to bring them inline with their rivals, whilst looking to improve their own performance.
Furthermore in the document we can see that the team broke the seal on the powerunit to replace the driveline for the MGU-K.  This is not particularly newsworthy as teams do this from time to time (all Mercedes powered cars did so in Singapore) but I'd suggest the change in the works teams case was made inline with their gear ratio change.  The reason being is that the MGU-K is geared, allowing for a smaller more efficient unit, changes in the gear ratios however will also mean that the MGU-K will be harvesting and dispensing energy at different rates than usual.  Mercedes AMG HPP therefore may have been working with the team on this change and decided to beef something up for reliabilty whilst playing their joker, but also offer the new solution to their customers too.

  1. Great info as always. One question though. Does this change has anything to do with Rosberg's retirement?
    Thanks

    1. The change has nothing to do with Rosberg's problem, that was to do with a fault in the wiring loom
