Abstract: A clutch arrangement for a hybrid vehicle powertrain, comprises: an input shaft (30) to be connected to a crankshaft (26) of an internal combustion engine (12); an output shaft (32) for connection to a transmission (20); a one-way clutch (50) for comprising an inner race (52) connected to rotate with the input shaft (30) and an outer race (54); a coupling hub (58) rotationally coupled with the output shaft (32); and a synchronizer ring (60) arranged between the coupling hub (58) and the one-way clutch (50), the synchronizer ring cooperating with the outer race of the one-way clutch. A coupling sleeve unit (62) is selectively and axially moveable across the coupling hub (58), synchronizer ring (60) and outer race (54) between three positions: a neutral position, a first position where the coupling sleeve unit couples in rotation said coupling hub, the synchronizer ring and the outer race; and a second position where the coupling sleeve unit couples in rotation the coupling hub, the synchronizer ring, the outer race and the inner race. Also presented is a powertrain comprising such clutch arrangement.
