A powertrain 21 for a hybrid vehicle has an internal combustion engine 27; an electric machine 28 (e.g. a motor/generator); and a power-split device 22 with an intermediate gear 216 transmitting torque between a first input gear 23 driven by the engine 27, a second input gear 24 driven by the electric machine, and an output gear 26 so that the ratio of the first input gear 23 to the second input gear 24 is 1:1. This provides a greater torque ratio between the output of the internal combustion engine and the output gear. The powertrain can have a bypass gear selectively coupled to the engine by a clutch. There may be a second electric machine (619, fig 6), and a battery (620, fig 6) can receive or deliver electrical energy to or from torque distributed by the power-split device.
