We construct the variable generalized Chaplygin gas (VGCG) defining a unified dark matterenergy scenario and investigate its essential cosmological properties in a universe governed by the Kaluza-Klein (KK) theory. A possible theoretical basis for the VGCG in the KK cosmology is argued. Also, we check the validity of thermodynamical laws and reimpelement dynamics of tachyons in the KK universe.
