As one of the possible extensions of Einstein's General Theory of Relativity,it has been recently suggested that the presence of spacetime torsion couldsolve problems of the very early and the late-time universe undergoingaccelerating phases. In this paper, we use the latest observations ofhigh-redshift data, coming from multiple measurements of quasars and baryonacoustic oscillations, to phenomenologically constrain such cosmological modelin the framework of Einstein-Cartan (EC) endowed with spacetime torsion. Suchnewly compiled quasar datasets in the cosmological analysis is crucial to thisaim, since it will extend the Hubble diagram to high-redshift range in whichpredictions from different cosmologies can be distinguished. Our results showthat out of all the candidate models, the torsion plus cosmological constantmodel is strongly favoured by the current high-redshift data, where torsionitself would be expected to yield the current cosmic acceleration. Specially,in the framework of Friedmann-like cosmology with torsion, the determinedHubble constant is in very good agreement with that derived from the Planck2018 CMB results. On the other hand, our results are compatible with zerospatial curvature and there is no significant deviation from flat spatialhypersurfaces. Finally, we check the robustness of high-redshift observationsby placing constraints on the torsion parameter $\alpha$, which is stronglyconsistent with other recent works focusing on torsion effect on the primordialhelium-4 abundance.
