Using nucleon quark-parton distributions obtained from inclusive leptoproduction and pion quark-parton distributions obtained from theoretical arguments we show that the Drell-Yan model does not reproduce a rather pronounced feature of recent data on dilepton production in hadron-hadron collisions. The dependence of the pN cross section on longitudinal dilepton momentum is much stronger than the dependence of the ..pi..N one, and quantitative calculations show that the model does not exhibit this feature.
