Possible manifestations of the E6 model in tau decays are considered, and the difference between the standard model with four families and E6 model predictions are discussed. It is shown that the normalized energy spectrum of the charged final lepton in tau decays is an effective tool for establishing new physics predicted by the E6 model.
