We present a multi-ion generalization of the AWSoM model, a 3D global magnetohydrodynamic (MHD) solar corona and inner heliosphere model with incompressible turbulence. The AWSoM model with charge states is further extended to include temperatures for the various heavy ion species. The coronal heating is addressed via outward propagating low-frequency Alfven waves that are partially reflected by Alfven speed gradients. The nonlinear interaction of these counter-propagating waves results in turbulent energy cascade. To apportion the cascaded turbulent energies to the electron and ion temperatures, we employ the results of the theories of linear wave damping and nonlinear stochastic heating. This heat partitioning results in a mass proportional heating among ions.
