They could have just changed the name to EV1 and kept the design of the Impact, and they would have had a runaway hit.
And the later EV1's had NiMH batteries that had about 150 mile range. It was too good, and they squashed them ...

Both Impact and EV1 were reported at Cd 0.19.
Later,during wind tunnel development of the 1999 PNGV 'Precept' concept,GM's team leader reported the EV1 at Cd 0.197.All along there were 'points' never mentioned.
And GM has down-graded their previously published Cds,so it's very difficult to make anything of their quanta.Too bad!
