A variator and a powersplit hybrid are connected in series. The variator is preferably a Milner epicyclic variator which has a ratio range well suited to this application. The variator permits the powersplit to operate at an optimized speed ratio. The variator further permits improved energy capture during regenerative braking. In some embodiments, clutches alternately connect the variator in series with powersplit and bypass the variator.
