That's interesting, checking Wikipedia I see that now. Rechecking all my manuals I see the 4x4 isn't acknowledged in any of them nor does the Panda 1981 to 1995 Haynes Manual. However the 2 deg. static seems to be common to all versions of the Fire engine up to and including the 1.1 injection. Perhaps a call to Trevor Nicosia would confirm the right figure.
