Boxer lovers, the next chapter in your love affair has just begun. Fuji Heavy Industries, parent company of 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 bore and stroke have 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. Follow the jump for the press release, and you can have a closer look at it the high-res image below.

looks like a cracking bit of kit. be good to see what figures these achieve once these new boxers go into production. am sure this new engine that's had ££££££££££££££ spent on engineering, designing & developing will be just as good ,if not even better than the last!!!

 

I thought they had to get something sorted for the Toyota/Subaru 2 seater........I guess this is it

Its about time they brought another engine out, you can only do so much with the one they have, and the 2.5 shows that up with its reliability issues, so a few new ones will fit the bracket nicely (and it looks a really nice engine too ).
See what it can produce power wise, will it be open, semi or closed deck? or a mixture of all 3?

Nice, whats the pulley to the bottom right?

 

Water pump would be my guess, as there dosen't seem to be much room behind the timing cover.

 

So a open deck that is half closed?
