In the SUBARU BOXER® engine cylinders lie flat, 180 degrees apart, and the pistons move horizontally. Like a boxer ready to fight clashing his gloves against each other, the pistons move simultaneously from opposite directions to balance out each others vibrations, and therefore allow a smooth and quiet drive. The piston movement allows the engine to be mounted lower in the center of the vehicle providing better balance, easier steering, and handling. The design of the Boxer engine allowed Subaru master the Symmetrical All-Wheel Drive by giving our vehicles better traction due to balanced weight of the vehicle.
