A powertrain has an engine, a continuously variable transmission, (CVT) a starting mechanism, and a final drive gearing. The CVT includes a continuously variable unit (CVU) in the form of a full toroidal traction unit, a planetary gear arrangement, and a pair of mechanical clutches that are connectable with the starting mechanism through a synchronizing assembly. The planetary gearing arrangement provides both a forward and reverse ratio path and a torque splitting or summing function.
