The Subaru Boxer engine is a piston engine designed by the Japanese car maker Subaru. The Subaru Boxer engine stands out from the type of engine which can be found in a car. Instead of pistons moving straight up and down, or at an angle like most engines, the Subaru Boxer pistons are laid flat and move parallel to the ground. This can be seen on the Subaru Boxer engine 3D animation down below. The unique punch, counter-punch action is inherently smoother, and the low, horizontal layout is more balanced and stable. And what's more, its alignment allows to feed power directly into the Subaru Symmetrical All-Wheel Drive system with maximum efficiency. The Subaru Boxer Engine improves stability and control by lowering a Subaru's center of gravity. The Boxer produces very little vibration, allowing for better riding comfort and improved engine durability.
