  In this paper we search for accelerating power-law solutions and ekpyrotic
solutions within minimal and maximal four dimensional supergravity theories. We
focus on the STU model for N=1 and on the new CSO(p,q,r) theories, which were
recently obtained exploiting electromagnetic duality, for N=8. In the minimal
case we find some new ekpyrotic solutions, while in the maximal case we find
some new generic power-law solutions. We do not find any new accelerating
solutions for these models.
