Neat.

I think the fist gen. Insight 1.0 litre engine had an offset crank as well. (Plus roller rockers and other stuff.)

Yup: InsightCentral.net - Encyclopedia - Honda Insight Offset Cylinder

Quote:
The engine block has a unique, offset cylinder design in which the bore center is offset 14mm from the crank center. Maximum combustion pressure occurs at a point where the connecting rod is straight up and down in the cylinder. In this position there is zero lateral force so friction and piston slap are reduced.

As a result of the offset construction, the combustion pressure is used more efficiently since the rod is near it maximum leverage point with the crankshaft.
