My favorite fact I used to tell people when I owned a 2008 Honda Fit was that parts of the L-Series engines was from Honda Powersport's Boat Motor lines. (the crankshaft if memory isn't failing me)

It's sad they're not making Fits anymore.

They should do more cross-over technology. Why do they make a motorcycle with a 1.8l flat 6 engine that shares the 73mmx73mm cylinder format of the early L-series car engine, but they can't bring an engine like that to cars? It would be smooth as hell.
