We have developed a next-generation hybrid event-by-event three-fluid hydrodynamic model, suitable for simulations of heavy-ion collisions in the energy range from few up to tens GeV per colliding $NN$ pair. At such energies interpenetration time nuclei is same order as lifetime system, however, this model treats initial phase hydrodynamically. Thanks that it more sensitive equation state than one-fluid models with states being parametrized or generated by transport approach. Hence, our well designed at collision energies, which matter vicinity quantum chromodynamics critical endpoint expected. The construction explained and basic observables like hadron spectra rapidity transverse momentum, elliptic flow are calculated.
