A swash plate engine comprises a counterbalancing swash plate assembly. In certain embodiments, the angle of a first swash plate assembly may be varied to vary the stroke of the engine. The swash plate assemblies may be operable such that during certain operating conditions of the engine a portion of one swash plate assembly passes at least partially through an interior passage provided in another swash plate assembly. In desirable embodiments, the stroke to bore ratio of the engine may be varied from greater than 1 to less than 1 depending on a vehicle operating parameter, such as the horsepower and/or torque of the vehicle engine and/or the position of a vehicle throttle pedal.
