A physically consistent model is presented for the early-type eclipsing binary system BF Aur, based on a simultaneous solution of its light and radial velocity curves. The less massive fainter (but hotter) secondary is smaller but almost Roche lobe filling component. The system is thus not reverse-algol. The absolute parameters of the system are found to be: Mh=3.3 Modot, Mc= 4.1 Modot, Th= 15600 K, Tc= 15400 K, Rh= 3.9 Rodot, Rc= 4.1 Rodot. More accurate radial velocity data are needed before uniqueness can be claimed for the model.
