Abstract: An engine and transmission arrangement for a four wheel drive vehicle comprises an engine arranged to extend substantially along a longitudinal center line of the vehicle. A gearbox receives power from the engine and a torque splitting device is connected to an output of the gearbox so as to pass part of the power to a rear final drive and part of the power to a front final drive. The front final drive and the rear final drive each includes a drive shaft which extends substantially along the longitudinal center line of the vehicle and at least a part of one of the drive shafts extends above a substantial portion of the engine.

Abstract: Components in or for self-powered vehicles, including in particular an integrated power unit in which a reciprocating-piston internal combustion engine and a transmission system are formed as a compact, single structural item in which the engine cylinders and the principal rotary members of the transmission are all located to one side of a plane which lies normal to the cylinder axes and includes the engine crankshaft axis. Compactness and simplicity are further promoted by designing the casing structure of the power unit to include an indivisible main component which encases parts of both the engine and the transmission system. The invention also includes features combined with and/or related to such a power unit, including a specific design for the transmission system, an arrangement of the induction system for the engine, installation arrangements for the power unit within vehicles, and related vehicle suspension systems.
