The dynamics and evolution of Bianchi type I space-times are considered in the framework of the four-dimensional truncation of a reduced theory obtained from N=2, D=5 supergravity. The general solution of the gravitational field equations can be represented in an exact parametric form. All solutions have a singular behavior at the initial or final moment, except when the space-time geometry reduces to the isotropic flat case. Generically the obtained cosmological models describe an anisotropic, expanding or collapsing, singular universe with a noninflationary evolution for all times.
