We perform a global analysis of Drell–Yan production of charged leptons and dineutrinos, the latter in missing energy plus jet events, in proton–proton collisions within the Standard Model Effective Field Theory (SMEFT). The combination allows for the removal of flat directions, sharper limits and to probe more couplings than the individual observables, which we show performing a fit to LHC-data. We also find that limits have only mild dependence on lepton flavor patterns; hierarchies in quark flavors are driven by the parton distribution functions. The strongest constraints are on couplings involving the first and second generation quarks, exceeding 10 TeV. Combining flavor and high-
data, the limits on electroweak and gluon dipole operators can be improved, by up to a factor of three, highlighting once more that a more global approach increases sensitivities significantly. We also estimate the improvements in reach over existing data for the high-luminosity LHC (HL-LHC) by 
, and future collider options such as the high-energy LHC (HE-LHC) by 
and FCC-hh by 
. To maximize the new physics reach kinematic cuts and binning needs to be adjusted to each quark-flavor separately.
