We discuss implications on the tension due to preferred-frame effects in the context of Hořava–Lifshitz gravity. By using a combination of low-redshift data (Sne1a, elliptical and lenticular galaxies, GRB’s, and quasars) we discuss the tension and its appearance as a preferred-frame effect, as well as present new constraints on the model parameter ; moreover, from the structure of the Friedmann equations, we argue that up to 36% of the Hubble tension can be explained by Lorentz-violating effects in a Hořava–Lifshitz scenario, and we briefly discuss the cosmographic behaviour of this model.
