nothing really. as far as i can tell its a pretty normal engine. there may be some subtle advantages but from an overall perspective its not important enough to be a deciding factor

Rampage · 10-27-2012, 12:56 PM

Low profile allows for a much lower COG than most engines.

wbradley · 10-27-2012, 01:07 PM

its a flat engine

mkiisupra · 10-27-2012, 01:15 PM

IIRC, the flat or horizontally-opposed design may deliver more torque for a similarly displaced inline or v cylinder design. Perhaps due to where the power is delivered from the piston/cylinders relative to the rotational cycle of the crankshaft.

Packaging. You can mount one longitudinally in the space of a transverse 4.

The lower CG is a benefit as well, which is why you see them a lot in motorcycles.

FRiSson · 10-27-2012, 01:28 PM

what about a 4-cylinder radial engine?

Celicadude · 10-27-2012, 01:32 PM

Also less vibrations since horizontally opposed pistons cancel the vibrations out, or so subaru says. Blah Blah Blah sciencey stuff Boxer Hooray!!!!!

This ^^^^

That's definitely the biggest advantage.

LeeMaster · 10-27-2012, 01:44 PM

As far as power goes for NA it is not as powerful as a Honda VTEC K series engine, but as far as we all can see the Boxer engine does seem to make/hold more power when going forced induction with just stock internals.

usually what happens is that the engine is so wide that it ends up being placed higher in the car negating any cog advantage you would gain otherwise.

Yep. Pretty much this is all

Only it doesn't. Have you looked under the hood? It's low
