FRIC (Front-to-Rear-Inter-Connected) suspension is not new to Formula One and even pre dates the 'Active Suspension' era of the early 90's but over the last few years the systems have become more an more complex. The teams desire for both suspension compliance and a consistent aerodynamic platform has led to vast improvements in the area.
This is where the FIA has decided to step in, with an imminent ban on inter-connected systems looming as early as the German GP in just over a weeks time. After the British GP the teams were issued with a technical directive by Charlie Whiting, an extract of which follows:
"Having now seen and studied nearly every current design of front to rear linked suspension system we, the FIA, are formally of the view that the legality of all such systems could be called into question."
They're insisting that such suspension systems could be seen as a breach of article 3.15 of the technical regulations, pertaining to moveable aerodynamic devices.
I briefly looked at FRIC early last year: Interlinked suspension and FRIC as it was a hot topic at the time, with Mercedes having seemingly made the most of their iteration.
A unanimous vote from the teams is all that will stave off the ban until the end of the season, with FRIC/Inter-connected suspension systems on the chopping block for 2015. With ALL teams running some form of inter-connected suspension (some much more mature than others) it's clear that it will have a dramatic effect on the grid as a whole if the ban came in immediately. However I think we can clearly see that this is the FIA flexing their muscles ahead of 2015, so as the teams can plan in advance for its ban, before even more advance systems become the construct of their design programmes.
It's also pertinent to remember the latest draft of the 2015 ratified by the WMSC also calls for some re-designs in terms of how the plank and skids are used going forward. FRIC suspensions allow for a much more aggressive rake than would be viable without such systems and so a redesign of both the plank/skids and banning of FRIC suspensions seems to tie everything up in a nice little bow, without dramatically affecting next years designs, of which the FIA will have been privy to and have likely taken this action because of.
