We calculate the decay width and the $\tau$-lepton energy distribution aswell as relevant moments for inclusive $\bar B \to X_c \tau \bar \nu_\tau$process including power corrections up to order $\Lambda_{QCD}^3/m_b^3$ and QCDcorrections to the partonic level. We compare the result with the sum of thestandard-model predictions of the branching fractions of the exclusivesemileptonic $\bar B \to (D, D^*, D^{**}) \tau \bar \nu_\tau$ decays as well aswith the relevant experimental data. Our prediction is in agreement with theLEP measurement and is consistent with the standard-model calculation of theexclusive modes. We discuss the impact from physics beyond the Standard Model.
