I think OUR air/oil cooled boxer is indeed outdated. It is also charming and still very functional. It has character.

It may indeed have an edge in CG and it has some inherent balance (much as an I6 does) but I don't think it has many other industry-leading characteristics. Maybe nice torque at lower RPM? It is certainly not the most efficient in power/weight, fuel economy, HP/displacement or similar measures. It is not the smoothest (many sporting I4's are smoother). Heck, it doesn't even sound good, lol!

What it does have is a link to the past, along with its charm.
