Correct me If I am wrong, but the S3 chassis is the same as a S5 from a torsional stiffness point of view.
Martin,
I was told by Mark Jackson that the new front end, including a massive cross tub brace where the coil over units used to be, behind the radiators, was intended to add to the torsional stiffness of the chassis front end.
The changes at the back were less significant, but did improve the package.
I suspect the new chassis will be better still.
I also wonder if the new S5 chassis includes suspension elements that we will see on the new car, allowing the Factory to get valuable road experience.
