A diesel engine (1) drives an axle (4) through a continuously-variable-ratio transmission (3), e.g. of the toroidal race rolling friction type. A flywheel system (5) is coupled to the input of the transmission (3) by reduction gearing (8, 9). Sprag clutches (2, 6) ensure that the transmission selects whichever is the faster of the engine or the flywheel, and a multiplate clutch (7) parallel with the flywheel sprag clutch (6) is engaged for regenerative braking. Parasitic losses during flywheel drive are reduced by operating the flywheel in a referred speed range coinciding with the engine speed range.
