We prove that smooth reparametrizations of the geodesic flow on a manifold of constant negative curvature are contact Anosov flows. In particular we give a new class of exponentially mixing Anosov flows. Moreover, this introduces the notion of C^0-contact and we prove that the classical Gray stability theorem that is known in the smooth case fails in this setting.
