Dimensional reductions of supergravity theories are shown to yield to specific classes of four-dimensional no-scale models with N=4, 2 or 1 residual supersymmetry. N=1 "maximal" supergravity lagrangian, corresponding to the "untwisted" sector of orbifold compactification of superstrings, contains nine families and has a no-scale structure based on the Kähler manifold [SU(3, 3+3n)/SU(3) ×SU(3+3n)]×[SU(1,1)/U(1)]. The quantum consistency of the resulting theories give information on the non Kaluza-Klein (string) "twisted" sector.
