The estimate on range goes like this : The EV1 original had lead-acid batteries (40 Wh/kg), and had a range of up to 75 miles.
The second generation had NiMH batteries (80 Wh/kg) and got 150 miles range.

If you would use Lithium-ion batteries (like Tesla motors does), you
get 160 Wh/kg, leading to 300 miles range for one charge.

GM claims it killed the EV1 because of the high cost -- and that was using cheap, safe batteries. Tesla can afford to use Li-ion
batteries because their car has a six-figure price tag.

Even the PHEV conversions for the Prius add $12k to the pricetag due to expensive, unsafe Li-ion batteries -- and that only gets
you a few miles of all-electric driving before the ICE has to kick in, not 300mi of EV range. You want 300mi? Drop an extra $50k
on batteries -- and maybe watch your car catch on fire or explode when the batteries overheat.

Battery technology and economics simply aren't at a stage yet where a pure EV is possible for the mass-market. PHEV is the best
we can do for now, and the massive market it creates for automotive batteries will help fund the development necessary for pure
EVs in a decade or two.

Of course you are right Stephen. And that's the way it will go.
Much slower than what is possible, and probably too slow to save GM.
Hopefully fast enough to avoid a major economic crisis, and hopefully fast enough to avoid that we make the same mistake again (like
uncontrolled CTL or GTL or some other fossil-fuel based 'solution'.
