Subaru Reveals All-New Boxer Engine


Yes, it's a picture of an engine, which is not ordinarily a cause for particular excitement, but this is the first image of Subaru's new-generation boxer engine - which will start filtering out to its road cars next year with the Forester.

A new Subaru motor is a pretty rare occurrence, too. This is only the third all-new iteration of the firm's boxer motor, the first coming in 1966 and the second with the Legacy in 1989.

The new engine will come in 2.5-litre and 2.0-litre displacements and will, says Subaru's parent company Fuji Heavy industries, improve on both the economy and performance of its forebear by around 10 per cent.

    And I thought I was on a petrolhead website!

    It will be interesting to see how it goes - they've gone to a longer stroke and smaller bore which I hope doesn't make the performance versions less rev-happy.

    I hope they go with forged internals for the STI variants. The hypereuretic (sp) crap they have in the current EJ257 motors blows chunks.

    Also, better fuel economy wont hurt. smile

    Sounds like they are still pushing for the mass market again by trying to make it more torquey, usually if they want to get more out the engine the bore goes up and the stroke down. You harly see any new impreza's on the road so i don't think its what people want.

    I think it is great that Subaru are sticking with the boxer format. It's a proper signature for the brand and its cars. It must be more expensive to produce than an in-line four, so in this "profits are king" manufacturing environment, it is good to see.
