We present a quasiparticle model based on a two-loop effective action equipped with hard thermal loop (HTL) dispersion relations and an effective running coupling strength. The model allows for an extrapolation of present QCD lattice results at small or zero chemical potential to larger baryon densities. The resulting QCD Equation of State is combined with the hadron sector to arrive at a usable form for hydrodynamical simulations of heavy-ion collisions over a large energy interval. The EoS is shown for several regions of the phase diagram and implications for quark/neutron stars are discussed.
