We construct new

gauged supergravities in four and five dimensions using generalized dimensional reduction. Supersymmetry is spontaneously broken to

with vanishing cosmological constant. We discuss the gaugings of the broken phases, the scalar geometries and the spectrum. Generalized orbifold reduction is also considered and an

no-scale model is obtained with three independent mass parameters.
