Is this just your guess or do you have same information you don’t want / can’t share?

In the issue of the Finnish magazine “Vauhdin maailma” where Janne Tuohino’s Fiesta was introduced they tell: “That the Fiesta is concerning the suspension geometry as a improved version compared to current Focus WRC. There are also solutions that where planned for the Focus WRC but homologation restriction prevented to implement them”.

That’s why I wonder why it would be different.

OldF: Focus uses trailing arms on the rear axle which is not possible under S2000 regulations (and new WRC also). Front McPherson struts are very similar in both cars, difference aside improved geometry is that Fiesta don't have ball bearings in higher suspension mounting points as they are not allowed for S2000.

The other difference is that S2000 cars must have all four shock absorbers of same type while Focus has different ones for front and rear axle (if I'm not mistaken).

I’m aware of that that in a S2000 all four dampers must be the same. That’s why also the rear dampers in the Fiesta are in similar angle compared to front dampers. The trailing arm was new for me. I know that in WRC they can choose from three different solutions: trailing arm, McPherson or the original. ;)

Know it then depends if the current WRC regulations regarding the suspension are also allowed in the 1.6T WRC. But if that is the case the why are they talking that the 1.6T WRC is based on S2000.

Yes the bis Q is then; What does based on mean ? Is it fully or 100% based on, or just loosely based on.

It seems that the new regulations are made available to the manufacturers, why not to the public ?

Yes, little bit strange. The engine and presumably also the gearbox is different from S2000 and if also the suspension is different what are there left, the body shell. :confused:

Some for sale here:

Maybe the sellers will then buy 1.6 Turbo versions instead?

Tuohino is out of money, he won't most probably buy anything.

Wait a second, ballbearings in higher mounting points forbidden? Is it really so? I think that it is the ballbearing patron used for the damper body as a slide bearing that is forbidden not in the top mounting parts. This ballbearing patron was quite fragile for dust etc. And therefore high in maintanance costs, that`s why it is forbidden. To my knowledge and also on the S2000 I´ve seen there are normal ballbearings in the topmounts!

Ah, sorry, You're right, my fault ;)

Where does this ball bearing actually situate in the damper?

Christian Loriaux also talks about the ball bearings in the dampers.

“However, new FIA rules which ban ball bearings in the dampers meant that significant research was needed into reducing the friction losses.”
