Spontaneous compactification of d = 11 supergravity on the squashed seven-sphere S/sup 7/ yields a spontaneously broken phase of the N = 8 theory on the round S/sup 7/ with SO(8) broken to SO(5)xSU(2) and with N = 1 or N = 0 supersymmetry according as the squashing is left or right handed. A feature unique to Kaluza-Klein supergravity is that the massless gravitino of the N = 1 phase comes from a massive N = 8 supermultiplet, as do the Higgs scalars. A solution is found with squashing and torsion but only in the right-squashed (N = 0) case.
