To answer your question, no one has done a controlled maximum range test, but if you peruse this forum you will see topics such as Maximum Range Remaining
We do not have a manual throttle or cruise control, most of us are reluctant to fully deplete the battery, hills and headwinds and temperature can greatly alter the results even if speed is held constant (at 62mph like Tony Williams does his test), and of course traffic makes a difference. I'd be willing to bet that two different drivers doing the same trip in two different i-MiEVs with the same average speed could get results that could probably vary by 20%.
As we all know, the misguided preoccupation with Range by non-EVers is something we have to deal with on a daily basis, whereas it is a non-issue once you get to driving the EV. Like I tell people, range is whatever I want it to be, and if it's too far even with hypermiling and I can't charge either along the way or at the destination, I simply don't take the i-MiEV. Doing the math ahead of time simply eliminates any "Range Anxiety" - hate that GM-fostered expression.
If we were to do a semi-controlled test such as Tony Williams has done, at 62 mph with a new battery pack I think we might be close to the i-MiEV's EPA rating of 62 miles, depending on how much we want to stress the battery pack. Here's a graph that I think gets us pretty close but perhaps errs on the conservative side: http://myimiev.com/forum/viewtopic.php?p=17565#p17565
More to the point, many of us have done over 70 miles on a single charge with no issues and not even stressing the battery pack ... all you need to do is slow down
