A hybrid-electric vehicle having a continuously variable transmission is provided. The continuously variable transmission further includes a forward disconnect clutch configured to selectively couple and decouple the continuously variable transmission and a first set of drive wheels. The hybrid-electric vehicle further includes a rear e-axle assembly, which allows the vehicle to operate in an electric-only mode, in which the vehicle is propelled with power generated solely by at least one electric power component. When the vehicle is operated in electric-only mode, the transmission disconnect clutch is disengaged, such that the continuously variable transmission is decoupled from the first set of drive wheels to allow the continuously variable transmission to operate in a low loss state. A method of transitioning an all-wheel drive hybrid-electric vehicle between an electric only mode and a hybrid mode, i.e., completing a “flying start,” is also provided.
