Subaru's diesel boxer

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.

Hiroyuki Ikeda, Subaru Europe's President, announced at the Paris Motor Show that the development of the H4 turbo-diesel boxer is almost complete. The design, pictured above, reveals two interesting tidbits: first, the turbo, which is traditionally housed towards the passenger side firewall on most Subarus, will be moved south of the crankshaft to retain the boxer's low center of gravity. Second, the new DOHC diesel will be outfitted with a timing chain, currently only seen on Subaru's H6 engines, and will be the first H4 so equipped.

If one of Subie's diesels does make it to this continent, expect it to reside under the hood of the new Forester.
