Geneva 2008 : Diesel Boxer

Fuji Heavy Industry (FHI) applied the world’s first Horizontally-Opposed Diesel Engine “Subaru Boxer Diesel” for passenger vehicles to the Subaru Legacy and the Outback. For the two models, the Subaru Boxer Diesel is mated with Subaru’s unique symmetrical AWD (All-Wheel-Drive) to achieve driving performance standards only Subaru is capable of. These standards include high-level stability and outstanding acceleration thanks to powerful low- and medium-speed torque.

On top of this, the two models adopt new electric power steering to achieve both improved fuel efficiency and fun to drive. They not only comply with the Euro 4 emission regulations, but realize top-level fuel economy for AWD passenger vehicles, thereby integrating driving performance into the environment.

The Subaru Boxer Diesel takes advantage of high rigidity of the horizontally opposed engine. It uses an aluminum-alloy cylinder block. With its engine width equivalent to that of a horizontally opposed petrol engine of the same displacement volume, it is 61.3-mm shorter in length, achieving top-level lightweight and compact design of the class.

Its unique layout allows the right and left pistons to negate each other’s inertia. This translates into smooth rotational balance, low vibration and superior quietness. Furthermore, thanks to excellent accelerator response, and with reduced friction and inertia resulting in smooth acceleration, the Subaru Boxer Diesel features engine characteristics worth the name of a sport diesel.
