SUBARU BOXER® Engine. Flat. Smooth. Smart.

Drawn from a century of intelligent performance, the horizontal layout of the SUBARU BOXER® engine combines balance with power and efficiency. And every Subaru comes with a SUBARU BOXER® engine.


Horizontal Design

Like the jabs of a boxer, where the engine got its name, the SUBARU BOXER® layout allows the engine to be positioned in-line with the drive-train for maximum transfer of power. Many other engines are transverse, or turned perpendicular, and can require additional drive-train components to transfer power, reducing vehicle efficiency.



The punch-counter-punch movements of the boxer's pistons cancel out each other for a smoother running engine without having to use additional components to counteract them as in many in-line and V-type engines.


 

Low Profile

With pistons moving horizontally, the SUBARU BOXER® engine has a flat, low profile, almost perfectly symmetrical, for a well-balanced vehicle. Its low profile can provide a lower center of gravity than other designs, helping provide quick handling response and flat, confident cornering.
