Two things (probably among others) that are keeping the C-111 from having a lower Cd are the arched front fenders, and the slab sides. The side taper only occurs at the very back.

I agree, the Insight has tapered sides, muddying the waters in this comparison.

The two cars with the best Cd's of any "production" cars are the EV1 and the XL1.

The C-111 is obviously not "perfect" and I think it is the virtual lack of side taper that is the difference. I think that Phil has said that side taper can reduce the Cd by as much as 40%, which is huge.
