We present results for final state charged-particle (pseudo-)rapidity distributions in p+p/p+p and Pb+Pb/Au+Au at ultra high energies (17.3 GeV{<=}{radical}(s{sub NN}){<=}14 TeV) from the Ultra-relativistic Quantum Molecular Dynamics (UrQMD-v2.3) model. In addition, excitation functions of produced charged-particle multiplicities (N{sub ch}) and pseudorapidity spectra are investigated up to CERN Large Hadron Collider energies. Good agreement is observed between UrQMD and measured pseudorapidity distributions of charged particles up to the highest Tevatron and SppS energies.
