This paper describes an electro-mechanical continuously variable transmission, the P-CVT. The basis for its functionality is a pericyclic gear train created by PVTT, Inc. coupled with a power-split variator system comprised of a pair of electrically coupled motor/generators. The kinetics and statics are analyzed, and power flow through the P-CVT is examined. In its basic configuration, it is capable of operating in CVT mode, fully electric mode, maximum power mode, or geared neutral mode, and providing regenerative braking. The addition of clutches further increases the flexibility of the system, allowing it to offer more operational modes, including more a series HEV mode as well as more 'conventional' parallel HEV operation. The P-CVT, in offers the potential for greater fuel-economy and superior emissions standards without sacrifice of performance through its capacity for CVT operation and suitability for hybrid powertrains.In the immediate future, the P-CVT lends itself for use in gas-electric hybrid vehicles, though it may readily be used in purely electric vehicles
