We study multidimensional cosmological models with a higher-dimensional
product manifold, that consists of spherical and flat spaces, in the presence
of a minimal free scalar field. Dynamical behaviour of the model is analyzed
both in Einstein and Brans-Dicke conformal frames. For a number of particular
cases, it is shown that external space-time undergoes an accelerated expansion
