Abstract: We study the cosmological evolution of an induced gravity model with aself-interacting scalar field $\sigma$ and in the presence of matter andradiation. Such model leads to Einstein Gravity plus a cosmological constant asa stable attractor among homogeneous cosmologies and is therefore a viabledark-energy DE model for a wide range of scalar field initial conditions andvalues for its positive $\gamma$ coupling to the Ricci curvature $\gamma\sigma^{2}R$.
