We estimate the power corrections (infrared renormalon contributions) to the
coefficient functions for the differential Drell-Yan cross-section
$d^2\sigma/dQ^2dy$, where $Q^2$ is the mass squared and $y$ the rapidity of the
produced lepton pair. We employ the dispersive method based on the analysis of
one-loop Feynman graphs containing a massive gluon.
