if they use that system right they could probably get some better tire life. I bet Lewis is happy about that suspension. Now all Merc need to do is build in a hydraulically controlled Traction Control system using KERS assisted engine braking. I wonder how long it will be until F1 cars are using KERS for engine braking exclusively.

If it is very successful no doubt the others will quickly protest it, anyone deemed to have an advantage by design is assumed to be breaking the rules somehow, they all do it and always assume that their version is fine , it's just the others that are illegal.

the full details of the fric have not been disclosed, but some points in this article need to be looked at...
it says that the system can be "adjusted" and has an "aerodynamic effect". now , that would appear to be in contravention of the rule that disallows a driver to have any control over aerodynamics. even last years lotus idea, which had NO driver input, was not allowed, so how exactly is merc increasing front rideheight during braking? (the opposite of normal physics) i cannot work out the mechanics of it, can someone else come up with the answer?

ferdi. in theory fluid not in suspension or under pressure would move to front, but the front suspension COMPRESSES under braking, so any hydraulic fluid would be forced into back. to raise the car at the front, would require considerable pressure pushing fluid from the rear to the front .that is why i cannot work it out

This system has been in use on the Redbull cars since 2011 at least and likely earlier. Its surprising that nobody of note has yet openly questioned their use of this while all eyes are on Mercedes for copying it.
If people recall , Redbull were told by the FIA to change the system slightly after they were accused of altering the ride height in Parc ferme of the Canada GP.

The so called FRIC ride height system Mercedes and Lotus are rumoured to be using must up to now be regarded as speculation, but the following should be born in mind.
The suspension system must be so arranged that its response results only from changes to the load applied to the wheels, and any suspension travel caused by any other force such as hydraulic or mechanical force is illegal.
But we have seen many a contradictory interpretation of the rules by the FIA even after first giving the go ahead to a team (Lotus ride height), nobody can be sure what the FIA interpretation will be (remember maclaren's F-DUCT) triggered by the driver's knee?.
