  We use the POWHEG method to perform parton-shower matching for Drell-Yan
production of W and Z bosons at the LHC at NLO QCD and NLO electroweak
accuracy. In particular, we investigate an improved treatment of the
vector-boson resonances within the POWHEG method. We employ an independent
implementation of the POWHEG method and compare to earlier results within the
POWHEGBOX. On the technical side, we provide the FKS formalism for
photon-radiation off fermions within mass regularization.
