Wonder if the Subaru ties with Toyota will eventually produce some sort of in-line engine in a Subaru car? The boxer engine certainly costs more to manufacture as previously mentioned when compared to an in-line engine.
Most "general aviation" aircraft engine are boxer types, with four, six, and a few eight cylinder versions out there. Lycoming and Continental are the big names in these air cooled boxers. Rotax, the Austrian (I think) company makes among many things, a water cooled boxer engine, both turbo and non turbo, that are used in some homebuilt aircraft, light sport aircraft, and aircraft with standard airworthiness certificates. These relatively small displacement engines make around 80 H.P. for the non-turbo to about 115 H.P. for the turbo version (or somewhere around there...)
Moto-Guzzi's motorcycle engine design isn't a boxer, but it's not an in-line design either. It's a two cylinder Vee design. Sort of like a BMW motorcycle, but with the two cylinders at some somewhat small angle separating the two which result in a "knee-knocker/knee-heater" for the motorcyclist.
I wonder if the real reason Subaru keeps the boxer is because surely the R&D costs have been recouped, they have all the necessary tooling to continue building it, and it's "traditional" for them.
Oh, and didn't some small German company build a few of these boxer engines? Some obscure little cottage industry type? Now what was their name? Folks Wagons? Something like that, I think.
