This thread here would seem to suggest that other cars in the MINI range might get the electronic diff soon:

So that's the speedo AND the E-diff as "selling points" for the
JCW which turn out not to be so exclusive after all. I can't say that I'm too impressed TBH. What'll be next - bigger brakes on all the Cooper S cars?
