Subaru's Third-Generation Boxer Engine - Click above for high-res image

Boxer lovers, the next chapter in your love affair has just begun. Fuji Heavy Industries, parent company of Subaru (http://www.autoblog.com/make/subaru), has introduced the latest, third-generation boxer engine that will relieve the second-gen after 21 years of service. This is a brand new lump, not a rework, and FHI has built a factory just to produce it.

The displacement, bore and stroke have all been increased, and it will be available with four cylinders in 2.0- and 2.5-liter displacements. The intake ports have been redesigned, lighter pistons and connecting rods offer reduced internal friction, and separate cooling circuitry for the block and the head are some of the changes that have resulted in a lower emissions and a ten percent increase in fuel efficiency. No power figures are being quoted yet, so we'll have to see how it measures up when it finds its way into production engine bays.

This new boxer will be Subaru's primary engine, and will first be seen in the Forester (http://www.autoblog.com/make/forester). Follow the jump for the press release, and you can have a closer look at it the high-res image below.
