Reggie,
I have test driven the i3, twice. Once not long after they came out, the dealer only allowed test drives in the range extender model, but I managed 60 miles of mixed city and fast A road driving without the helper engine cutting in.
Since then BMW has upgraded the battery, from 60kw to 94kw and the dealers view is that 125 to 150 miles is realistic.
I was both impressed and disappointed. It is quick, the regenerative braking is very effective and the car is fun to drive. But the ride is BMW harsh and the thing rolls more than I like. As a local runabout it would be good, but there are a many, many cheaper alternatives.
