Let X be an algebraic variety covered by open charts isomorphic to the affine space and q: X' → X be the universal torsor over X. We prove that the automorphism group of the quasiaffine variety X' acts on X' infinitely transitively. Also we find wide classes of varieties X admitting such a covering.
