Subaru's Third-Generation Boxer Engine – Click above for high-res image
The design of the horizontally-opposed engine has a myriad of benefits. One of the most common is its compact design, which allows the center of gravity to be lower in the host vehicle. Additionally, since the boxer's pistons cancel out much of the vibration, the rotational balance is second to none. Both of these advantages will lend themselves to the advent of the first boxer diesel, which will find a home within a variety of Subaru models in Europe and possible even here in the States.
