    I will try to explain it again, what I think.

    When accelerating from a corner you have: open front diff (defective locking system), locked centre diff (works OK), locked rear diff. (works OK).

    In that situation Front and rear axle spin at same speed (locked c. diff) - rear axle works OK, - front inside wheel spins (because it is unweighted) outside rear wheel transfers same amount of torque (open f. diff) as inside one (very little or zero, if wheel is lifted)... effectively you have RWD.

    I see, thanks for clarifying J_n_z – yes, if the problem was on the front diff only, then this will be possible.

    Question is, does rally Corsica has so many sharp corners to cause front insight wheel to spin?

    I think that it can happen in all corners not only in tight ones, it can happen also when cutting corner over grass, or it is half dirty... It also can become difficult to save oversterings.

    Definitely WRC car need some locking in f. diff.

    guys you must be a bit confused,front diff at wrc cars have no hydraulics at all.They are plated diffs.
    Focus rs 4wd system is a simple and cheap way to have 4wdrive. There is no comparison to active center diff from Mitsubishi evos various editions,which is a proper active diff.

    .
    no its not like that.Accelerating from corners you don't have an opened front diff,neither locked rear diff.

    The point was IF it was defective, it could act as an open diff. All speculation, as we really don't know at the moment.

    according to Msport they had problems with hydraulics.
    Front diff has no hydraylics at all,thats why I said that some are confused.

    Thanks dimviii, just from curiosity point of view - do we know this for certain (about the mechanical front diff on the current WRC cars) and if yes, one more question – how do we know this ?
